WMACH-PROAIR™

OVERVIEW

Designed to exceed the expectations of typical Variable Air Volume (VAV) specifications, the ReliableControls® MACH-ProAir™ is a fully programmable BACnet Building Controller (B-BC) with feature richversatility. Eight base models are available with different hardware point capacities includingcombinations of up to 3 universal inputs, 3 universal outputs, 5 TRIAC outputs, an actuator, and a flowsensor. All MACH-ProAir™ models can supervise up to 4 SMART-Sensors or 2 SMART-Sensor™

EnOcean Accesspoints.

PRODUCT FEATURES

PRODUCT FEATURES

NEW MEMORY PARADIGM

The MACH-ProAir™ employs a new memory utilization paradigm. There are no longer fixedmemory allocations for each object type. The available database memory can be usedwhere needed, giving maximum application flexibility. For example, one application mayrequire 16 PID Loops, but only 20 variables, while another application may require 64variables and 2 PID Loops. Both applications can be accommodated by a MACH-ProAir™

controller, because this new memory model is not only more efficient and robust, but isalso much more customizable. In order to fully utilize and optimize the MPA, a basicunderstanding of the new memory model should be developed.

The MPA has two memory locations used by the custom pan file during normal operation,database memory, and trend memory. This is indicated in the Network Status worksheetas shown in Figure 2. When adding to the database of a MACH-ProAir™ controller, it is agood idea to be aware of remaining database and trend memory. RC-Studio® will not allowadditional database memory to be used if it exceeds the remaining memory in thecontroller.

FIGURE 2: NETWORK STATUS WORKSHEET - SHOWING DB AND TREND MEMORY REMAINING

• BACnet Building Controller (B-BC) with 5 year warranty

• Sturdy attractive enclosure with removable connectors

• Software configurable universal input types

• Dynamic memory allocation provides unparalleled object-creation flexibility andoptimized onboard data acquisition

• Robust MRAM memory stores all data through a power outage or brownout

• Downloadable online library of standard application codes for fast programmingand setup

WMACH-PROAIR™

DB REMAINING

The DB Remaining column in the Network Status worksheet indicates the bytes andpercent remaining in the database (flash) memory. In Figure 2, 5,312 bytes remain and arefree to use for additional database. Creating new objects always uses database memory.Many new objects use very little memory, especially if long descriptions are avoided.

TREND REMAINING

The Trend Remaining column in the Network Status worksheet indicates the bytes andpercent remaining in the trend memory. In Figure 2, 5,340 bytes remain and are free to usefor additional trending. Trend memory, as the name implies, is used when creating Single-point and Multipoint Trend Logs, adding points to a Trend Log, or when creating variables.

Be aware that creating a Multipoint Trend Log with 8 points uses approximately 6 KB oftrend memory. In addition, since a Trend Log is also an object, a few hundred bytes ofdatabase memory are also consumed.

INSTALLATION

OUT OF THE BOX

MACH-PROAIR PACKAGE CONTENTS

MOUNTING

The MACH-ProAir™ VAV controller is designed to be mounted directly on the sheet metalof an air duct. The controller may be attached by screwing the controller directly to thesheet metal. Models without a damper actuator ship with two self-tapping #8 screws (a 3/4" and a 1 1/4” Robertson drive). Models with a damper actuator ship with one self-tapping#8 , 3/4" Robertson drive screw.

TIPS FOR MOUNTING THE MACH-PROAIR:

• 1 MACH-ProAir™ controller

• 1 package containing one self-tapping metal screw (for actuator models) or 1package containing two self tapping metal screws (for non-actuator models)

• 1 drill guide template for mounting

• 1 wiring guide

• Use the self-tapping #8 metal screws supplied with the MACH-ProAir™ (do notuse bevel headed or wood screws),

• The MPA should be mounted indoors in a dry, relatively clean environment freefrom corrosive fumes (If the actuator is mounted outdoors, a protectiveenclosure must be used to shield the actuator.),

• From a performance standpoint, it is best to mount the MPA directly onto thedamper shaft,

• The MPA, as shipped from the factory, accommodates a 3/8” to 1/2” diameterdamper shaft (A shaft up to 1” in diameter can be accommodated by ordering alarger coupling from Belimo),

• Sometimes it is necessary to take manual control of the damper by pressingand holding the clutch button on the face of the MPA (After the desired positionis achieved, the clutch button should be released. Anytime manual control of theactuator is used, the actuator should be calibrated. Refer to the ActuatorCalibration section of this manual.).


Power Wiring

MACH-PROAIR™

POWER WIRING

The MACH-ProAir™ requires power from a Class 2, 24 VAC/VDC, 25 VA power supply. Oneor more controllers can be powered from the same source. Ensure that the polarity is thesame if multiple controllers share the same power source. The Status LED will light if thepower polarity is crossed.

Ground yourself before touching the controller to avoid damaging the electronics. Touch agrounded metal surface to discharge static electricity.

The MACH-ProAir™ controller is intended to be installed in accordance with the NationalElectric Code or the Canadian Electric Code, Part 1, and in a manner acceptable to thelocal authority having jurisdiction or in accordance with IEC 60730-1 Clause 11.6.3Mounting of Independently Mounted Controls.

Do not connect any peripheral devices to the same power source as the MACH-ProAir™

controller.

Use only a Class II (UL) or Class III Equipment Safety Isolating Transformer certified to IEC61558-2-6.

The 24 VAC return/neutral wire must be grounded to the building’s Earth ground.

Apply minimum 4.0–5.5 in-lb torque for tightening field wires into terminal blocks. Use 26–14 AWG (0.13 mm2 – 2.1 mm2) wires.

External wiring connected to the controller must be relieved from strain and twisting.

INPUT CONFIGURATION

FIGURE 7: REMOVABLE INPUT CONNECTORS

UNIVERSAL INPUTS

An MPA has either one, or three universal inputs, depending on the model.

SENSOR TYPE

The electrical characteristic for each input is set up using the Inputs worksheet in RC-Studio® 2.0 Revision 1.76 or greater. The MACH-ProAir™ is the second Reliable Controls®

device to offer software-configurable sensor types – the MACH-ProZone™ being the first.The conventional onboard input jumpers found on older MACH controllers do not exist onthe MACH-ProAir™, and the input sensor type is configured entirely through the use of RC-Studio®. By selecting the appropriate setting for the Range column in the Inputsworksheet, the appropriate value in the Sensor Type column is automatically selected asshown in Figure 8.

FIGURE 8: INPUTS WORKSHEET WITH AUTOMATIC SENSOR TYPE FOR THE MPA

Each universal input can be configured as one of four possible sensor types: Thermistor,0–10 V, Dry Contact, or 4–20 mA. After the proper range has been selected, verify that theappropriate sensor type is indicated. If not, click on the value in the Sensor Type columnto toggle through the four sensor types.


OUTPUT CONFIGURATION

FIGURE 9: OUTPUT CONNECTORS - MODEL MPA-36-F

An MPA has up to three universal outputs and up to five TRIAC outputs, depending on themodel. The range of each output is set using RC-Studio®. The electrical configuration foreach output type is determined at the factory, based on model, as either universal orTRIAC.

UNIVERSAL OUTPUTS

Universal outputs provide 0–12 VDC at a maximum of 75 mA. The outputs are configuredwith RC-Studio® to be binary (two-position) or analog (modulating). A given output isdesignated as a universal output at the factory and cannot be changed in the field. Anoutput labelled OUT# is an indication of a universal output.

Figure 10 shows the recommended method for wiring an MPA universal output to a typical0–10 VDC modulating actuator.

The maximum voltage measured by an input is 10 VDC. The minimum voltage measured byan input is 0 VDC.

If a universal output is to be used for control of a pilot relay, care must be taken to ensurethe pilot relay draws less than 75 mA.

TRIAC OUTPUTS

TRIAC outputs provide a single pole, normally open TRIAC contact designed to switch 24VAC loads, with a current load ranging from 0.02 to 0.5 Amp. The TRIAC output cannot beused to switch DC loads.

All MACH-ProAir™ models except the MPA-12 base models have the ability to share acommon 24 VAC (R ) among some or all of the TRIAC outputs. This saves considerabletime when wiring.

THE TRIAC SHOULD NOT BE USED FOR:

A given output is designated as a TRIAC output at the factory and cannot be changed inthe field. An output labelled BO# is an indication of a TRIAC output.

COMMUNICATIONS

The MACH-ProAir™ controller has two communication ports (SMART-Net and EIA-485). The removableSMART-Net connector and the RJ-11 SMART-Net jack are internally connected and are considered oneport.

The removable SMART-Net connector is used to connect to remote SSLs and SSEAs.

The RJ-11 SMART-Net jack may be used to connect to remote SSLs and SSEAs, or it may be used toconnect an X-Port-2 converter, allowing communications to a PC running RC-Studio® or RC-Toolkit™

software.

The MS/TP-Net connector is used to connect the MPA to an EIA-485 network that communicates usingthe BACnet MS/TP datalink.

BACNET DIRECT CONNECT

A BACnet direct connection may be used to connect to a standalone MPA, or to anetworked MPA. After a connection is established, RC-Toolkit™ can be used to configurethe MPA, and RC-Studio® can be used to provide complete programming and operationof the MPA.

FIGURE 14: X-PORT-2™ BACNET DIRECT CONNECTION

TO MAKE A BACNET DIRECT CONNECTION WITH RC-STUDIO OR RC-TOOLKIT

When running RC-Studio® on a PC with an X-Port-2™ connected directly to an MPA, anRCP direct connection will not work. Instead, select Access > Systems List > BACnetDirect Connect from the bottom of the Systems List dialog box. When using RC-Toolkit™,MPAs will only respond to the MSet and OS Send applications.

BACNET NETWORK APPLICATIONS

The MACH-ProAir™ can only communicate on a BACnet® network using the EIA-485electrical standard, and the BACnet MS/TP data-link. It is not possible to configure aMACH-ProAir™ to communicate using RCP protocol.

In accordance with the BACnet® standard, the MACH-ProAir™ can communicate at 9600,19200, 38400, and 76800 baud. The controller features auto-baud detection, allowing it tosense the communication speed used by other devices on a MS/TP network andautomatically configure its own communication speed to match. If the communicationspeed is changed on a functioning network that includes MACH-ProAir™ controllers, thecontrollers will sense the change and automatically reconfigure within 1 to 2 minutes.

1 Connect the CC-VC-C cable between the X-Port-2™ network port and the RJ-11jack at the bottom right of the MPA.

2 Observe the patterns of the flashing lights on the X-Port-2™. When the PC/Modem status light begins flashing once per second, the PC/Modem port canbe connected to the PC.

MAXIMUM CABLE LENGTHS

The total combined cable length for a single SMART-Net™ communication bus from thecontroller, to the final SMART-Sensor™ should not exceed 75 meters or 250 feet (based on24 AWG cable). The actual maximum functional network length can vary depending on thetype of cable used. For longer networks and total cable length, use appropriate data cablewith a lower resistance and capacitance per meter (foot). Installing one or more SSXmodules can increase the total cable distance that can be installed.

Poor modular connector installation, high-resistance connections, or excessive cable lengthmay cause the SMART-Net™ voltage to drop below the minimum necessary for SSEA/SSLcommunication. In this state, the SSEA/SSL will not communicate with the controller.

Database Press and hold the Reset button, apply power to the controller, andrelease after 2 Status LED flashes (approximately 2 seconds). Thisoperation clears the custom pan file from the controller. MSetinformation such as the Controller Address is not cleared. After clearingthe database, a valid pan file must be loaded to the controller in order toreestablish functionality.

MSet Press and hold the Reset button, apply power to the controller, andrelease after 10 Status LED flashes (approximately 10 seconds). Thisoperation clears the database, and also restores the MACH-ProAir™ tofactory defaults, including network configuration settings such asaddressing. After clearing the MSet, the controller will disappear fromthe network, and will have to be reconfigured with all communicationparameters. A valid pan file will also have to be loaded in order toreestablish functionality.

CONFIGURATION

OVERVIEW

The MACH-ProAir™, MACH-ProZone™, and SMART-Space™ Controllers are all designed sothat one or more units can be connected to a live MS/TP network and powered up withoutrequiring any initial configuration, and without affecting existing communication on thenetwork. This is possible because of the following features:

TO CONFIGURE A MACH-PROAIR FOR AN MS/TP NETWORK, EITHER;

Both methods are described in the next two sections.

RC-TOOLKIT: MSET TOOL

The MSet application is a software application found in RC-Toolkit™. The main function ofthe MSet application is to allow one or more configured or unconfigured controllers to bediscovered, named, and addressed from a single location.

• Baud rate configuration is not required, because the controller senses thenetwork baud rate and configures itself to communicate at the same rate, and

• Every MACH-ProAir™ ships without a MAC address, allowing unconfigured unitsto remain silent and undiscovered on an MS/TP network when powered up.

• Use the MSet Tool found in RC-Toolkit™ 2.0 version 2.50 or greater to configurethe network parameters, or

• Use a Setup Tool (or an SSL in Setup Tool mode) to configure the networkparameters.

RC-Toolkit™ 2.0 version 2.50 or greater is required to communicate to the MACH-ProAir™.

A standalone MACH-ProAir™ cannot be MSet using the X-Port-2™ unless the MAC addresshas been configured. The X-Port-2™ requires at least one transmitting controller on thenetwork for auto-baud detection to occur.


TO USE THE MSET APPLICATION FOR MPA SETUP

1 Connect a PC to the target controller using an X-Port-2™, or to a network nodewith BACnet access to a network that connects one or more MPA controllers.

2 Launch RC-Toolkit™.

3 If using a direct connection, ensure that the correct communication port isselected in the Port field.

FIGURE 23: DIRECT CONNECTION AND COMMUNICATIONS PORT

4 If using TCP/IP to connect, enter values for the IP Address field and the BACnetPort field of any IP-connected device on the BACnet® internetwork.

PROGRAMMING

POINT REFERENCES

The MACH-ProAir™ is a BACnet® protocol device, therefore it does not contain any RCPpoint types. This means that internal RCP points and RCP points in remote devices cannotbe referenced.

The MACH-ProAir™ can read from and write to BACnet® objects in any device on theconnected BACnet® internetwork, up to fixed limits.

The MACH-ProAir™ controller can read/write BACnet® object information from/to MACH-Pro series controllers and MACH-Global™, MACH1™, MACH2™, and MACH-Stat™

controllers. The MACH-ProAir™ controller can also read/write directly from/to BACnetpoints in the MA, MPZ, and the MPA.

The MACH-ProAir™ can also share information with a SMART-Space™ Controller (SSC). Inorder for an SSC to read from objects in a MACH-ProAir™, either the SHARE or SHARE-NET function must be written in Control-BASIC running in the MACH-ProAir™.

CONTROL-BASIC

COMMANDS SUPPORTED

Since the MACH-ProAir™ is a BACnet® protocol device, there are some differences inavailable Control-BASIC commands. Table 9 shows the commands available (highlightedin green) for use in the MPA.

MEMORY LIMITS

Even though the MACH-ProAir™ uses a dynamic memory model, there are somelimitations that apply, such as limits to the memory size of Control-BASIC programs. Thereis no limit to the number of Control-BASIC programs, however each program can be nolarger than 3200 bytes. Also, the sum of all Control-BASIC program sizes cannot exceed8500 bytes. The current size of each Control-BASIC program, and the total size of allprograms is displayed on the Control-BASIC worksheet.

OBJECT LIMITS

TOTAL OBJECTS

The maximum number of objects the MPA supports is 128.

SYSTEM GROUP

The maximum number of objects supported on a MPA System Group is 80.

ALARMS

In the MACH-ProAir™, alarms are implemented entirely using the BACnet® protocol andrequire the use of a MACH-Pro series host controller running firmware version 7.50 (orgreater). Programmers can configure alarms using the traditional Control-BASIC or withthe BACnet intrinsic alarm method. Both methods result in alarms being broadcast acrossthe internetwork, stored in Reliable Controls® devices with alarm logs, and annunciated atBACnet® Operator Workstations.

CONTROL-BASIC ALARMS

This technique uses traditional Control-BASIC alarm statements to create BACnet® alarmsusing the BACnet algorithmic alarm method. Custom alarms are simply programmedusing the Control-BASIC DALARM and ALARM statements, and the controller takes careof the rest.

Whenever an alarm state occurs, as determined by Control-BASIC statements, an EventEnrollment object is dynamically created. These objects can be seen in the Object Listworksheet as shown in Figure 41. When the alarm is cleared, the Event Enrollment objectwill be removed from the Object List worksheet.


FIGURE 41: OBJECT LIST WORKSHEET SHOWING SYSTEM ALARMS

SYSTEM ALARMS

BACnet algorithmic alarming and event enrollment objects are also used to generateSystem alarms for fault conditions in the MACH-ProAir™. The system alarms supported areNo Program, SMART-Sensor Offline, and Stale Wireless.

BACNET INTRINSIC ALARMS

The MACH-ProAir™ supports standard BACnet intrinsic alarms on all inputs, outputs, andvariables. Intrinsic alarms are configured using simple dialog boxes accessed through RC-Studio® worksheets, and result in the InAlarm property being set on objects that are in analarm state. The following is an example of configuring an intrinsic alarm for a return airtemperature sensor input.

TO CONFIGURE AN INTRINSIC ALARM

Device offline system alarms are generated by the host MACH-Pro series controller.

8 Place the Alarm dialog box in Update mode.

The MPA can support up to 16 active alarms. If a 17th alarm occurs before any of theoriginal 16 alarms have been reset or acknowledged, the oldest alarm will be lost.

Intrinsic alarm is active


MULTISTATE VARIABLES

RC-Studio® supports several pre-defined multistate units, and also allows programmers tocreate custom multistate units. The MPA allows either type of unit to be used when definingmultistate variables.

As with all Reliable Controls® BACnet-only devices, the value of multistate variables startat 1 and proceed to the number of elements in the text range. For example, the value ofthe multistate variable Cool/Heat/Auto/Off multistate text range is 1/2/3/4. For the Off/On/Auto multistate text range, the corresponding value of the multistate variable will be 1/2/3.This differs from the RCP multistate reference which begins with the value 0.

As shown in Figure 44, the Custom Units worksheet supports eight custom multistate textvalues.

INTEGRATED FLOW CALCULATION

To simplify a critical part of the control, the MACH-ProAir™ automatically calculates thevolumetric flow based on the velocity pressure and box diameter (VAV1002-DIAM). Theunits of the flow setpoint (VAV1002-FLO-SP) always follows the range selected for velocityinput (VAV1002-VP).

To change the engineering increments from imperial to metric, simply change the rangeof Input 4, and all the related flow variables will automatically change. This also allowschanging of the engineering units for the controller, without having to switch to acorresponding pan file. Please note, the MACH-ProAir™ ships default with imperialengineering units (WC, inches, CFM). Additionally, VAR1, the duct diameter, can be set inimperial and have all of the flow panels report in metric, or vice-versa, if you wish.

AUTOMATED DAMPER CONTROL

The MACH-ProAir™ has fully integrated the damper control directly in the firmware. Whenenabled by the Flow Control variable (VAV1002-FLO-CTRL), the controller willautomatically drive the damper to follow the Flow Setpoint (VAV1002-FLO-SP) to within5%.

ACTUATOR CALIBRATION

The MACH-ProAir™ calibrates its motor position by opening and closing the damper everytime the controller’s power is cycled. The MACH-ProAir™ includes the ability to monitor,trigger, and even disable actuator calibration using Control-BASIC. Note that the followingcode does not need to be continuously executed because these settings are retained asa part of the database, and subsequently, the pan file.

(4) VAV1002-FLO (Volumetric Flow) The rate of volumetric air flow calculatedfrom the measured pressure (VAV1002-VP) and the ductdiameter (VAV1002-DIAM).

(5) VAV1002-FLO-SP (Flow Setpoint) The target setpoint flow that the applicationwill try to achieve when running.

(6) VAV1002-FLO-CTRL (Flow Control) Controls whether or not the application isrunning. Yes = running, No = stopped.

(7) VAV1002-FLO-DB (Flow Deadband) A deadband around the flow setpoint(VAV1002-FLO-SP), so that the application will stop in thearea of the setpoint rather than continually trying to movethe motor and achieve a perfect match.

RUNTIME REPORT

The MACH-ProAir™ is a BACnet® protocol device, and therefore does not include any RCPpoints, including traditional RCP Runtime Logs. Instead, RC-Studio® 2.0 Update 1.70 (orgreater) includes a Runtime Report, which assembles properties from BACnet® objectsinto a single report that is nearly identical to the traditional RCP Runtime Logs worksheet.There are four ways to access a BACnet Runtime Report: selecting from the main menu,selecting in the System Tree, selecting a Runtime Report keyword annotation on a SystemGroup, or via direct access.

For the MACH-Pro series, MACH-ProWeb series, MACH-ProZone™, and MACH-ProAir™,there is no need to configure the Runtime Report as all binary points are automaticallytracked. Although, the Log checkbox for variables on the Runtime Report worksheetshould be enabled as desired.

The Tables worksheet is used to create and display all of the tables in a single controller.Each table reference includes the unique table name (32 characters), an In Value (X) - Unit,and an Out Value (Y) - Unit. Double-clicking a table reference in the Name column willopen the associated Table worksheet.

FIGURE 55: TABLES AND TABLE WORKSHEETS

The Table worksheet contains two columns, labelled In Value (X) and the Out Value (Y)columns, along with the appropriate unit. Each Table worksheet has a maximum of 15rows for defining scaling coordinates.

In the above example, a table was created for a static pressure transducer with a standard0–10 VDC output signal. The table is used to scale the VDC signal into units of Pascals.Row 2 is necessary to prevent VDC noise from being translated into false Pa readings. Row4 is necessary to prevent the table from reading zero in the event the input signal risesbeyond 10 VDC.

NETWORK STATUS WORKSHEET

The BACnet Network Status worksheet has been expanded to support database, trendmemory, Net Ins, and Net Outs for the MACH-ProAir™.

FIGURE 56: NETWORK STATUS WORKSHEET


DB REMAINING

The DB Remaining column in the Network Status worksheet indicates the bytes andpercent remaining in the database (flash) memory. In Figure 56, 5,312 bytes remain andare free to use for additional database. Creating a new object will always consumedatabase memory. Objects such as variables use very little memory, while schedules andControl-BASIC programs can use much more.

TREND REMAINING

The Trend Remaining column in the Network Status worksheet indicates the bytes andpercent remaining in the trend memory. Figure 56 indicates that 5,340 bytes remain andare free to use within the trend memory. Trend memory, as the name implies, will be usedwhen creating Single-point and Multipoint Trend Logs, adding points to a Trend Log, orwhen creating variables.

Be aware that creating a Multipoint Trend Log with 8 points and a default length of 128samples, for example, will use 5.5 KB of trend memory. In addition, since a Trend Log isalso an object, a few hundred bytes of database memory will also be used.

NET INS

The Net Ins worksheet is used to display the number of network points imported into theMPA controller from other controllers on the network. Click the ellipsis button in the Net Inscolumn on the Network Status worksheet to access the Net Ins worksheet in which all ofthe Net In points for the MPA controller are listed.

The Net Ins data is preserved on a power loss and is stored in the pan file. The Functionand Period fields are user-adjustable.

FIGURE 57: NET INS WORKSHEET

In Figure 57, the point 1000AI20 is an imported point from device #1000. When points arereferenced by the Control-BASIC program FC2-MAD-PRG, a new entry is created in theNet Ins worksheet.

Each Control-BASIC program can be no larger than 3,200 bytes and the total size for allControl-BASIC programs cannot exceed 8,500 bytes.

In Figure 58, point 2000AV37 is a variable on a MACH-ProSys™ that has been written fromthe MPA via the following Control-BASIC code.

45 2000AV37 = 17

Point AV4 has been shared on the local network from the Control-BASIC program FC2-CALCS via the following statement.

90 A = SHARE( AV4 )

The Increment column allows for the control of the minimum value change before thenotification is sent to the destination.

It is not required to use the SHARE statement unless points are being networked to anSSC, in all other cases the process is automated from the requesting device.

MACH-ProAir™ (MPA) Motor Control ExecutionMain Loop

MPA integral actuator motor control is performed by the firmware using a procedure outlined in this flow chart to maintain the measured airflow (AV4; FLO) at the provided airflow setpoint (AV5: FLO-SP).

1. Motor timing is scan rate independant.

2. Motor control application is only executed on -A-F models with FLO-CTRL (BV6) set to yes.

3. Error is calculated by the difference between measured airflow and effective airflow setpoint ( error = FLO (AV4) – FLO-SP (AV5) ).

4. Default airflow deadband, FLO-DB (AV7) is 10%.

5. Minimum motor drive time is 500 ms.

APPLICATIONS

Several standard applications recommended for use with the MACH-ProAir™ controller areposted on the Reliable Controls® website at http://www.reliablecontrols.com/support/dealers/technical/std-apps.html. The following is an example of the content of thesestandard applications.

VARIABLE AIR VOLUME AIR TERMINAL UNIT WITH REHEAT

OVERVIEW

This standard application provides an example of a typical VAV application with a floatingreheat valve actuator. The database has been developed using a MACH-ProAir™ MPA-12-A-F and a SMART-Sensor™ LCD (SSL). The sequence of operation designed to becompliant with the requirements of ASHRAE 90.1-2010 and the International EnergyConservation Code (IECC) 2012 for local zone terminal unit control including:

The MPA-12-A-F features one (1) universal input and two (2) TRIAC outputs. The universalinput is used for a discharge air temperature sensor; recommended for reheat applicationsand required to comply with ASHRAE 90.1-2010/IECC 2012. An SSL is used to providespace temperature, space temperature setpoint, user-interface, and optional motiondetection for unoccupied bypass. Consistent with the MACH-Air™, all air flow sensorcalibration and Test and Balance (T&B) functionality is available using the Flow Setupfeature of the SSL.

• Flow setpoint modifications for reheat operation,• Dual minimum and maximum airflow setpoints,• 3°C (5°F) Space temperature setpoint deadband between heating and

cooling,• Discharge air temperature limitations,• Local scheduling, occupancy override, Night Set-Back (NSB) and Night

Set-Forward,• Unoccupied zone isolation, and• Terminal load feedback to primary air handling equipment to facilitate reset

discharge air temperature and duct static pressure reset routines.


MANUAL DAMPER OVERRIDE

In this application, an operator or technician is provided with the ability to manuallyoverride normal damper control operation using the multistate value FLO/DMP-CTRL-OVRand to manually define the effective airflow setpoint using the analog value FLO/DMP-SP-OVR.

Table 15 outlines the functional modes of FLO/DMP-CTRL-OVR and the correspondinguses of FLO/DMP-SP-OVR.

TEMPERATURE CONTROL MODES

There are five temperature control functional modes in this example. Each modedetermines how the terminal unit should respond based upon the system and ambientconditions. The functional mode is automatically determined by the controller.Alternatively, the functional mode could be overridden by an operator or as part of a globalstrategy; for instance, preventing reheat operation if there is no heating hot water available.The effective functional temperature control mode is indicated using the MSV HVAC-MODE as outlined in the following table.

TABLE 16: MSV HVAC-MODE MODES OF OPERATION


1 Ventilation Ventilation Mode is active when the spacetemperature is in the deadband between the spacetemperature heating setpoint and the spacetemperature cooling setpoint.

In this mode the damper will modulate to maintain theeffective minimum airflow setpoint and the reheatvalve is closed.

2 Cool Cooling Mode is active when the space temperatureis greater than the space temperature coolingsetpoint. The effective airflow setpoint will modulatebetween the minimum and maximum cooling airflowsetpoint based upon space temperature deviation.

In this mode the damper will modulate to maintain theeffective airflow setpoint and the reheat valve isclosed.

3 Reheat Reheat Mode is active when the space temperature isless than the space temperature cooling setpoint andthe effective airflow setpoint is at minimum. Theeffective airflow setpoint and discharge airtemperature setpoint will modulate between theminimum and maximum heating airflow setpointbased upon space temperature deviation.

In this mode the damper will modulate to maintain theeffective airflow setpoint and the reheat valve willmodulate to maintain the discharge air temperaturesetpoint.


OCCUPANCY MODES

Each terminal unit can be configured to operate according to local BACnet® schedule andcalendar objects or according to a network occupancy command. This applicationfeatures six occupancy modes. These occupancy modes can be automaticallydetermined by the controller or manually commanded by an operator or as part of a globalstrategy.

The effective functional occupancy mode is indicated using the MSV OCC-MODE asoutlined in Table 17.

4 Heat Heat Mode is active when the supply air temperaturefrom the air handling system exceeds the local spacetemperature. The airflow control loop action isreversed since warm air is being provided to theterminal unit. The effective airflow setpoint willmodulate between the minimum and maximumheating airflow setpoint based upon spacetemperature deviation.

In this mode the damper will modulate to maintain theeffective airflow setpoint and the reheat valve isclosed.

5 Initialize Initialize Mode is active when the controller isinitializing the onboard damper actuator due topower-up.

In this mode the damper will cycle from closed toopen and the reheat valve is closed.

TABLE 17: MSV OCC-MODE MODES OF OPERATION


1 Occupied In the Occupied mode as determined by the localschedule or network command the terminal unit willoperate according the temperature control mode.

2 Bypass The Bypass mode provides temporary occupancywhen the unit is scheduled or commanded to beunoccupied. When the bypass timer has expired, theunit will revert to unoccupied.

In the Bypass mode the terminal unit will operateaccording the temperature control mode.

3 Standby The Standby mode is commanded by and operatoror as a part of a global strategy.

In the Standby mode the effective airflow setpoint iscommanded to the Standby airflow setpoint.

4 Unoccupied In the Unoccupied mode as determined by the localschedule or network command the damper iscommanded to maintain an effective airflow setpointof 0.

5 Night Set-Back (NSB)

During the Unoccupied mode the Night Set-Back(NSB) mode is initiated when the space temperaturefalls below the NSB setpoint and remains active untilthe space temperature rises above the NSB setpointby the configured temperature deadband.

In the NSB mode, the effective airflow setpoint iscommanded to the maximum heating airflowsetpoint and the reheat valve is allowed to modulateto maintain the NSB setpoint.

5 Night Set-Forward (NSF)

During the Unoccupied mode the Night Set-Forward(NSF) mode is initiated when the space temperaturerises above the NSF setpoint and remains activeuntil the space temperature falls below the NSFsetpoint by the configured temperature deadband.

In the NSF mode, the effective airflow setpoint iscommanded to the maximum cooling airflowsetpoint and the reheat valve is closed.


FLOATING REHEAT CONTROL

The MPA-12-A-F features two TRIAC outputs providing simple floating control of a reheatvalve in this application. The programming utilizes the enhanced Control-BASIC timingprecision for accurate floating actuator control based upon the output of the PI reheatcontrol loop. The floating actuator position is calculated based upon accumulated activeopen and close command drive times. The actuator position calculation is resynchronizedon the fly when the actuator is commanded to less than 5% or greater than 95% and whenthe unit transitions to the Unoccupied mode or out of the Reheat mode.

TERMINAL LOAD

A very simple example of terminal unit load is provided in this application using thecomposite analog value (AV) TERM-LOAD. This AV can be monitored by the air handlingunit controller to dynamically reset primary air-side system response so as to consumeonly the minimal amount of mechanical heating, cooling, and fan energy necessary tosatisfy actual terminal unit demand.

When the reheat control loop exceeds an output of 95% a value of -1 is added to thecomposite AV TERM-LOAD to indicate a request for increased primary supply airtemperature. When the reheat control loop falls below 85% the value of -1 is removed fromTERM-LOAD. This feedback can be used in closed loop control strategy to reducemechanical heating energy consumption by the primary air handling unit by resetting thedischarge air temperature setpoint based upon terminal unit demand for heating.

When the flow control loop exceeds an output of 95% a value of 1 is added to thecomposite AV TERM-LOAD to indicate a request for decreased primary supply airtemperature. When the airflow control loop falls below 85% the value of 1 is removed fromTERM-LOAD. This feedback can be used in closed loop control strategy to reducemechanical cooling energy consumption by the primary air handling unit by resetting thedischarge air temperature setpoint based upon terminal unit demand for cooling.

When the damper position exceeds an output of 95% a value of 10 is added to thecomposite AV TERM-LOAD to indicate a request for increased primary duct staticpressure. When the damper position closes below 85% the value of 10 is removed fromTERM-LOAD. This feedback can be used in closed loop control strategy to reduce fanenergy consumption by the primary air handling unit by resetting the duct static pressuresetpoint based upon terminal unit demand for airflow.

ALARMS

This application also provides a sample of beneficial alarm programming that can be usedto notify the operator of potential areas of concern with the terminal unit while minimizingnuisance alarms.

For example, an alarm is generated when the damper is closed if airflow is sensed. Furtheralarms are only generated after thirty minutes of occupied operation. If the measuredairflow is less than 50% of the airflow setpoint for longer than five minutes an alarm isinitiated, possibly indicating an airflow issue. If the temperature rise across the reheat coil



USER GUIDE

MACH-PROAIR™

is less than 5°C (10°F) after five minutes of a reheat valve command of at least 40%, analarm is initiated, possibly indicating a heating hot water, coil, or actuator issue.

Finally, if the space temperature deviation from the space temperature heating or coolingsetpoints exceeds 1.5°C (3°F), a terminal unit space temperature alarm is generated.

NETWORK VARIABLES

Supply air temperature to the terminal unit must be written to AV NET-SAT to enable thecontroller to automatically activate Heat Mode when the supply air temperature exceedslocal space temperature and for alarming temperature rise across the reheat coil. Anoccupancy command can be written to BV NET-SCHED for global scheduling. Duct staticpressure can be written to AV NET-DUCT-STATIC-P for display on the System Group.Terminal load can be read from AV TERM-LOAD for trim and respond reset sequences.
