Features and benefits

A All models utilize a scroll compressor that are environmentally friendly by utilizing R-410A refrigerant. Use of the scroll compressor technology means a simple internal design, fewer moving parts, equating to a quiet, reliable, easy to service and efficient system. Internal compressor protection is standard and compressors include protection to prevent liquid damage.

Total system design - A TXV is used for precise metering on the 4-5 ton products. A single circuit, single compressor design is used on the 4-5 ton units for cost effectiveness and reliability without compromising quality.

System protection - Liquid line filter-driers, high and low pressure safeties are standard on each independent refrigerant circuit. Suction line sensors monitor temperature to prevent possible liquid flood back to the compressors and also protect against loss of charge and coil frosting.

B Balanced outdoor fan design makes for a quieter unit -The outdoor condenser fans are dynamically balanced for

better performance and reliability. The direct drive fan design mounted to the fan grill allows for quick and easy service. Where other's components might fail at extreme temperatures Our units are tested and rated up to 125°F (52°C) ambient cooling operation.

C Convertible filter rack - No tools required for easy field conversion of the filter rack to accommodate either 2-in. (51 mm) or 4-in. (102 mm) filters. Units ship with MERV 4 throwaway filters standard; however MERV 8 and MERV 13 filters can be easily added through the tool-free filter access panel to meet LEED requirements. Refer to physical data tables for filter size details.

D Units come with the new state of the art Smart Equipment™ control system. The new unit control incorporates the best of the already proven Smart Equipment™ controls and creates a more robust, intelligent control. The goal of this control is to utilize cutting edge technology making the equipment easier to install, operate, and service. All units are Factory commissioned, configured, and run tested.

5543990-XTG-E-0719


Phase monitor - All ZM products come with a factory-installed phase monitor that is designed to prevent unit damage. The phase monitor shuts down the unit in an out-of phase condition.

Versatile - The Smart Equipment™ control can be configured to use with a standard thermostat (easy to connect screw terminals), a zone sensor, or can be setup to communicate with multiple BAS communication protocols to integrate with building automation systems.

Reduce field installed complexity - Each unit comes equipped with factory installed supply air, return air, and outdoor air temperature sensors providing key temperature readings thus reduce field installed complexity.

On-board USB port - The new control comes with a long list of features including data logging, current and previous system faults and software update capabilities using the on board USB port and common flash drive. Energy use monitoring capabilities allow custom tailoring to allow a system to work more efficiently at all times and occupancy levels. Self test and start-up reports also available from the board VIA the USB port.

Embedded LCD display - The board has a easy to read, built-in LCD display and easy to use navigation joystick and buttons allowing the user to quickly navigate the menus displaying unit status, options, current function, supply, return and outdoor temperatures, fault codes and other information.

Safety monitoring - The control monitors the outdoor, supply, and return air temperatures and the high and low pressure switch status on the independent refrigerant circuits. On units with heating the gas valve and high temperature limit switches are monitored on gas and electric heating units. The control also monitors the voltage supplied to the unit and will protect the unit if low voltage due to a brown out, or other electrical issue occurs.

Low ambient - An integrated low-ambient control allows units to operate in the cooling mode down to 0°F (-18°C) outdoor ambient without additional components or intervention. Optionally, the control board can be programmed to lockout the compressors when the outdoor air temperature is low or when free cooling is available.

Anti-short cycle protection - To aid compressor life, an anti- short cycle delay is incorporated into the standard control. Compressor reliability is further ensured by programmable minimum run times. For testing, the anti-short cycle delay can be temporarily overridden with the push of a button.

Fan delays - Fan on and fan off delays are fully programmable. Furthermore, the heating and cooling fan delay times are independent of one another. All units are programmed with default values based upon their configuration of cooling and/or heating capacity.

Nuisance trip protection and three strikes - To prevent nuisance calls, the control board uses a three times, you're out philosophy. The high, low-pressure switch, anti-freeze protection, low voltage or heating high limit must trip three times within two hours before the unit control board will lock out the

associated compressor. The same safety must trip three times before a hard lockout will occur.

E Robust design - Each unit is designed with an embossed top to increase structural support and ensure rigidity. The unit has a powder paint exterior finish including a industry leading 750-hour salt spray rating. All units are painted with a long lasting, powder paint that stands up over the life of the unit.

F Full perimeter base rail that fits on many existing curbs - This product was designed with the replacement market in mind which is why it fits on many existing curbs in the field but it also takes into account the new construction market by being versatile and sturdy. This unit is equipped with heavier gauge and innovatively designed base rails to prevent damage from transporting and rigging.

5543990-XTG-E-0719


G Coils - All evaporator coils utilize copper tube with aluminum fin design for proven reliability and performance.

H Rigid mounted blower assembly - Dynamically balanced indoor fans ensure better performance and reliability. Large access panels for easier access, service, and maintenance. X13 belt drive (standard static option) available on 4-5 ton products. The X13 motor technology offers several benefits w/ respect to efficiency, operation, comfort, and cost when compared to other motors.

Drive selection

1. Determine side supply duct application.

2. Determine the desired airflow.

3. Calculate or measure the amount of external static pressure.

• Add or deduct any additional static resistance from the “Additional Static Resistance” table.4. Using the operating point determined from steps 1, 2 & 3, locate this point on the appropriate supply air blower performance

table. (Linear interpolation may be necessary.)

5. Noting the RPM and BHP from step 4, locate the appropriate motor and, or drive on the RPM selection table.

6. Review the BHP compared to the motor options available. Select the appropriate motor and, or drive.

7. Review the RPM range for the motor options available. Select the appropriate drive if multiple drives are available for the chosen motor.

8. Determine turns open to obtain the desired operation point.

Example

1. 3200 SCFM, Bottom Supply Duct application

2. 1.8 IWG

3. Using the airflow performance table below, the following data point was located: 1071 RPM & 2.52 BHP.

4. Using the RPM selection table below, Model ZY and Size 08 (7.5 Tons) is found.

5. 2.52 BHP exceeds the maximum continuous BHP rating of the 2.4 HP motor. The 3.7 HP motor is required.

6. 1071 RPM is within the range of the 3.7 HP motor.

7. Using the 3.7-HP motor and High-Static drive, 0.5 turns open will achieve the required 1071 RPM.

Altitude and temperature correction for CFM, static pressure and power

The information below should be used to assist in application of product when being applied at altitudes at or exceeding 1000 feet above sea level.

The air flow rates listed in the standard blower performance tables are based on standard air at sea level. As the altitude or temperature increases, the density of air decreases. In order to

use the indoor blower tables for high altitude applications, certain corrections are necessary.

A centrifugal fan is a constant volume device. This means that, if the RPM remains constant, the CFM delivered is the same regardless of the density of the air. However, since the air at high altitude is less dense, less static pressure is generated and less power is required than a similar application at sea level. Air density correction factors are shown below.

Use the examples below to assist in determining the airflow performance of the product at altitude.

Example 1: What are the corrected CFM, static pressure, and BHP at an elevation of 5,000 ft. if the airflow performance data is 3,000 CFM, 1.4 IWC and 2.0 BHP?

Solution: At an elevation of 5,000 ft. the indoor blower will still deliver 3,000 CFM if the RPM is unchanged. However, the altitude correction must be used to determine the static pressure and BHP. Since no temperature data is given, we assume an air temperature of 70°F. The Altitude/Temperature Factors show the correction factor to be 0.832.

Corrected static pressure = 1.4 x 0.832 = 1.16 IWC

Corrected BHP = 2.0 x 0.832 = 1.66Example 2: A system, located at 5,000 feet of elevation, is to deliver 3,000 CFM at a static pressure of 1.4 inches. Use the

unit blower tables to select the blower speed and the BHP requirement.

Solution: As in the example above, no temperature information is given so 70°F is assumed.

The 1.4-inch static pressure given is at an elevation of 5,000 ft. The first step is to convert this static pressure to equivalent sea level conditions.

Sea level static pressure = 1.4 in. / .832 = 1.68 in.

Enter the Supply Air Blower Performance Table at 3,000 CFM and static pressure of 1.68 inches. The RPM listed is the same RPM needed at 5,000 ft.

Suppose that the corresponding BHP listed in the table is 2.0.This value must be corrected for elevation.

BHP at 5,000 ft. = 2.0 x .832 = 1.66
