2.1 Control modes

The control mode can be changed by pressing the MODE button (one or multiple times) on the 186RC. The following operational modes can be selected:

FAN COOL HEAT AUTO VOD

The next paragraphs are describing the different modes.

2.1.1 Mode 1: FAN

In this mode the unit will operate without checking the return air (T1_indoor) or outdoor temperature (T2_outdoor) sensors.

2.1.1.1 Fan

Fan speed default is medium if Mode is changed but can be changed with FAN button. The FAN button can select High, Med and Low speed for the separated Supply fan and Exhaust fan. The values are not settable.

2.1.1.2 By-pass Valve

By-pass valve is always closed.

2.1.2 Mode 2: COOL

During the summer season the COOL mode either can be manually selected with the remote control or automatically controlled via the BMS (Building Management System) inputs When BMS J5(5-13) is ON (closed) and season select input J5(1-9) is closed, the mode will be COOL. The BMS input has priority over the remote control setting.

2.1.2.1 Fan



In COOL mode the damper valve will be controlled in accordance with following conditions.

temp_MIN_Outdoor_Cooling = 10°C temp_MAX_Outdoor_Cooling = 32°C

By-pass valve close conditions: 1. T2_outdoor > T1_indoor and

T3_setpoint < T1_indoor

2.1.3.3 Electrical heating elements

Maximal 3 electrical heating elements can be connected.

Configuration 1: 1,2 or 3 heating elements after the WTU unit, in the supply air to room duct. In this configuration the heating elements are switched on basis of T1_indoor temperature and T3_setpoint.

Configuration 2: 1 heating element before the WTU unit in the fresh air inlet duct. 2 or 3 heating elements after the WTU unit, in the supply air to room duct. In this configuration the heating elements 2 and 3 are switched on basis of T4_Room_sensor temperature and T3_setpoint. Heating element 1 is switched on basis of T2_sensor <= -7.

The algorithm for the 3 electrical heaters is how higher the delta temperature how more power is selected. For example Delta temperature from 10 degrees is full power.

Under table shows how the heaters are turned on and off with the same KW. For example Heater 1 = 3 KW, Heater 2 = 3 KW, Heater 3 = 3 KW

Under table shows how the heaters are turned on and off with the different KW. For example Heater 1 = 1 KW, Heater 2 = 2 KW, Heater 3 = 5 KW

Heater configuration is written in EEPROM (§2.5.3 Parameters).

2.1.3.1 Fan



In HEAT mode the damper valve will be controlled in accordance with following conditions.

temp_MIN_Outdoor_Heating = 15°C temp_MIN_Outdoor_Heating = 35°C

During the summer season the HEAT mode either can be manually selected with the remote control or automatically controlled via the BMS (Building Management System) inputs When BMS J5(5-13) is ON (closed) and season select input J5(1-9) is open, the mode will be HEAT. The BMS input has priority over the remote control setting.

By-pass valve close conditions: 1. T2_outdoor < T1_indoor and

T3_setpoint < T1_indoor and T2_outdoor <15°C

2. T2_outdoor > T1_indoor andT3_setpoint > T1_indoor andT2_outdoor >35°C

2. T2_outdoor > T1_indoor -3 andT3_setpoint > T1_indoor -2 andT2_outdoor <35°C



2.1.5.1 Fan

Fan speed controlled with VOD and cannot be controlled with FAN button.


By-pass valve is always closed.

2.2 BMS

Building Manage System can be set on the Main board. If the BMS is on the Remote Controller is not controlling the heat recovery unit. If the BMS was active and the heater(s) were on, the heat recovery unit fans stay on for 120 seconds when the heat recovey unit is switch off. The BMS uses 3 inputs from the Main board.

2.2.1 BMS

The BMS function dis (en) - abled the remote control controlling the temperature.

2.2.2 BMS unit

The BMS unit on and off function turns the unit on and off. The fans are going off in off state.

2.2.3 Season select

The BMS uses the input for the deferens between summer 2.1.2 Mode 2: COOL and winter 2.1.3 Mode 3: H.

2.3 Filter check

On the Remote Controle the filter check is displayed if filter time over is. Filter timer is in 10 hours and default 1200 hours. The filter timer is deceased if the fans are on.

2.4 Modbus

With the communication protocol MODBUS you can connect a HMI. The default setting for the Modbus (slave) address is 1. The address setting resides in the e2prom and can be changed if required. This can be done with the help of Labvision via the Senso Argus link connection Modbus communicates using words (the contents of 16bit holding registers). The data that is offered by the 186MN is organised as a list of bytes. Read/Write address (of the holding registers). If bit Write disable is set then MN is communicating with RC. If bit Master is set the RC cannot be controlled by hand or BMS. If bit Master is reset the Modbus can read all data from the system. In the next paragraph is a description of Modbus configuration and architecture and example for read and write.

This HMI uses the following commando’s in table on next page.

2.1.4 Mode 4: AUTO

In the auto mode the control selects automatically, dependent on the outdoor temperature, if it is summer or winter season. In accordance with the selected season the unit will work in cool or heat mode as described in previous paragraphs.

Summer season is selected when T2_outdoor > season_auto_switch_temp+ season_ hysterese_up

Winter season is selected when T2_outdoor < season_auto_switch_temp - season_hysterese_down

2.1.5 Mode 5: VOD

When VOD (Ventilation On Demand) is selected the fan speed is controlled by the analog 0.10V input signal. At 0..1V the fans are running at minimum VOD speed and at 9..10V the fans are running at maximum speed for VOD. In between the fan speed is linear controlled.

The min and max fan speeds for VOD are adjustable and are always within the appliance min/max fan speeds. The min/max fan speed range for VOD is divided in three smaller ranges. When the actual fan speed is within the lowest range, the display shows only one fan bar, etc.

(*) Depending on the type of Modbus software used, the holding register addressing range starts either at 0x0000 or at 0x0001. If your Modbus software starts addressing from 0x0000 you can use the holding register addresses shown in the table above. If your Modbus software addressing range starts at 0x0001 then add 1 to the holding register addresses listed in the table above. This is also true for the various test tools available for Modbus…

Tabdial32 starts at 0x0000. ( http://www.leroy-automation.com/free%20softwares.html ) The Tabdial32 tool does not support the write single holding register command.

Modbus Tester ( http://www.modbus.pl/downloads.htm ) starts at 0x0001.(**) If 2.4 byte is written the Remote control writes the 3 and 4 nr bytes also in his memory of the display.

2.4.4 Working with Modbus

The Modbus communication goes from the Main (MN) board, MN is slave. The data goes from MN to the Remote Control (RC) with communication protocol Senso Argus link. The RC is master and the MN is slave. The Modbus is 8 times faster as the Senso Argus Link communication. First the data has to be send to RC and back before the Modbus master can send the next command. Modbus does not communicate with MN after 60 seconds the RC is going out and Modbus is no longer master.

The figure is showing the communication between RC and MN with Modbus and Senso Argus Link. The blue line is read communication and the red is write communication beginning with the Modbus packets. In the next paragraphs the packets are explained.

2.4.4.1 Read Commando

The table on the right shows an example of a Read frame. MN is receiving Read commando 03 MN asks data of Read buffer RC sends Write module data to Read Buffer of MN

2.4.4.2 Write Commando

The table on the right shows an example of a Write frame. MN is receiving Write commando 06 MN Write buffer receives data MN Set write disable bit in MN Write buffer MN Set write disable bit in MN Read buffer RC reads MN Write buffer in Read module RC Write module reads Buffer RC Reset write disable bit in Write buffer RC Write module sends to MN Read buffer MN Reset write disable bit in MN Write buffer

2.5 System set-up

2.5.1 Fan speeds

The control works with two different types of min/max limits:

1. Absolute fan speed min/max settingsSettings are factory set and cannot be changed. The fans are always operating within these limits

2. VOD fan min/max settingsThese min/max settings are applicable when the unit works in VOD mode, but are always within the absolutelimits (no. 1). The limits will be corrected with the fan balancing offset (§ 2.5.2) if not zero.

2.5.2 Fan balancing

Fan balancing can be used to adjust the supply and exhaust air ratio. This can be done by changing the parameter offset_supply_exhaust_air.

In case of a negative offset the exhaust fan speed is below the supply fan speed In case of a positive offset the exhaust fan speed is above the supply fan speed. When the offset is 0 the exhaust and supply fan speed is equal.



Negative Offset Positive Offset

When VOD (§ 2.1.5) is selected the target fan speed applies to supply fan and is used as reference to adjust the exhaust fan with an offset. The offset also applies to the minimum and maximum fan speed settings in such a way that always an offset remains,

2.5.2.1 Conditions

There are several conditions for the fan balancing: Exhaust_Fan_MAX > 90 Exhaust_Fan_MAX Exhaust_Fan_MAX Exhaust_Fan_MIN Exhaust_Fan_MIN Supply_Fan_MAX Supply_Fan_MAX Supply_Fan_MIN Supply_Fan_MIN Supply_Fan_MIN

<= 255 >= 90 <= 255 < Exhaust_Fan_MAX > 90 <= 255 >= 90 < 255 < Supply_Fan_MAX

VOD_MAX_Fan_speed <= Exhaust_Fan_MAX VOD_MIN_Fan_speed >= Exhaust_Fan_MIN

3.1.3 Timer function

The timer function can be used to program block times in which the unit is operating. Outside the blocks the unit is off.

The timer function makes it possible to program 2 on/off times per day.

Program Timer Blocks Press TIMER button for 3 seconds, day MON starts blinking, all other LCD segments are off

Press DAY button (one or more times) to select the day to be set Press OK to confirm, the selected day is permanent on

The temp display shows which means timer block 1 “on” time can be programmed Adjust the “on” time with the DAY and SCHEDULE buttons, press OK to confirm

Next the timer block 1 “off” time can be programmed, the temp display shows Again adjust the “off” time with the DAY and SCHEDULE buttons, press OK to confirm

Next the timer block 2 “on” time can be programmed, the temp display shows Adjust the “on” time with the DAY and SCHEDULE buttons, press OK to confirm

The temp display shows which means timer block 2 “off” time can be programmed Again adjust the “off” time with the DAY and SCHEDULE buttons, press OK to confirm Now the next day starts blinking and can be programmed accordingly as described above.

To exit the programming mode press OK for 3 second or wait 1 minute



Additional features

A specific “on” or “off” time can be deleted by pressing RESET when programming the

time block. If deleted the time display shows: and the time is not used. When for example the unit is “on” on Monday and no “off” time is programmed that day

anymore, the unit remains “on” until the first “off” time is reached the next day(s).Thesame sequence is used when the unit would be “off”

3.1.3.1 Examples for monday

Example 1 – normal blocks Time display Block

1st “on” time - unit starts on Monday at 8:00

1st “off” time - unit stops on Monday at 12:00

2nd “on” time - unit starts on Monday at 14:00

2nd “off” time - unit stops on Monday at 18:00

Example 2 – overlapping blocks Time display Block


1st “off” time - unit stops on Monday at 12:00

2nd “on” time – No action Time programmed before 1st stop time, unit remains off

2nd “off” time - No action Unit was not operating, so remains off.

Example 3 – Ignored times Time display Block


1st “off” time – No action Unit remains “on”

2nd “on” time – No action Unit remains “on”

2nd “off” time - unit stops on Monday at 18:00

4 Labvision With Labvision the system can be tested and programmed. Application Labvision runs on PC. PC is connected Senso Argus USB mouse to the Senso Argus Link. For each board and functions are project defined. There are 4 projects defined in Labvision. But first a short description how to program the E2Prom.

4.1 Program E2Prom

To program E2Prom select in the menu ‘Tools’ above in the screen.

Select to program board RC has address 2 or MN has address 100.

After pushed on ‘OK’ button the board is programmed with the selected file.

E2Prom was programmed correctly.



4.2 RC

This project shows all E2prom variables and variables that are set when the Remote Control is running. By pointing at a red label the variable can be changed.



4.3 MN

This project shows variables that are set when the Main Controller is running. The buttons can be pushed to change a variable. Each connector on the board has a color to see where the variable is connected physically.



4.4 MN/RC modbus

This project shows variables that are set when the Main Controller is connected with Remote control and modbus. The information on the screen are divided in several items:

1. Read buffer in MN has the data which reads by Modbus master.2. Write buffer in MN has the data which written by Modbus master.3. Read/Write in RC is the modbus information.4. Modbus Device address is set in E2Prom5. Mobus_write_enable shows when the Modbus master can write.6. Exit timer shows when the Modbus master is disconnected when no data is send.7. TX and RX bytes between Modbus master and MN.

4.5 RC display

This project shows information on Remote Control and Timer saved information.



5 System Test If the software is changed we do several tests to make sure the software is correct. Test the different modes of the system:

1. MODBUS2. BMS3. RC4. ERROR5. MODE HEATER6. MODE AUTO7. MODE VOD

5.1 Modbus

The program CAS Modbus scanner can receive and send the correct commando’s. Labvision is used to check if all variables are correct. The next test actions are after power up the system:

5.1.1 Labvision

Select in labvision project F4. Clear History with Menu-> tools-> clear history.

At the bottom you can see if Senso Argus link is correct the blue in gray balk is running.By checking the checksum list you can see the correct checksum of RC and MN board.



5.1.2 Modbus tester production 06

The table has A to Q commando’s for the Modbus tool. Check all commando’s in labvison screen. By step I in table the display is off but the fans are on for cooling the heaters. In the first table we test the Purge time, run, mode, master Modbus, exhaust fan, supply fan, set point degrees.
