Bard Dehumidification Refrigerant Reheat Circuit
This model provides a unique dehumidification circuit for periods of low outdoor ambient temperature and high indoor humidity conditions.Refer to Specification Sheet S3588 for the standard features of the base units and this manual for electrical data.
Dehumidification Circuit
The dehumidification refrigerant reheat circuit is controlled by a dehumidification valve directing the refrigerant gas to the normal condenser during periods when standard air conditioning is required. During periods of high indoor humidity, a humidistat senses the need for mechanical dehumidification. It then energizes both the compressor circuit and the dehumidification valve, thus directing the hot refrigerant discharge gas into a separate desuperheating condenser circuit, which reheats the conditioned air before it is delivered to the room. The refrigerant gas is then routed from the desuperheating condenser to the system condenser for further heat transfer. When the humidistat is satisfied, the system automatically switches back to normal A/C mode and either continues to operate or turns off based on the signal from the wall thermostat. The result is separate humidity control at minimum operating cost. See Figure 1 on page 2.
Dehumidification Sequence of Operation
Dehumidification is controlled through the thermostat (if capable) or through a separate humidistat. On a call for dehumidification mode of operation, the compressor and dehumidification valve of the unit are energized through circuit R – D to provide dehumidification. Dehumidification will continue until the humidistat is satisfied.
Any time there is a call for circuit R – Y1, the dehumidification mode will cancel and the system will return to cooling operation.
Balanced Climate™ Mode
It is recommended to enable Balanced Climate mode and utilize a 2-stage thermostat to enhance the dehumidification performance and comfort.
NOTE: To activate this mode, the jumper between Y1 and Y2 on the low voltage terminal strip needs to be removed.
In units with an economizer vent, balance climate mode should not be used. The Y1 and Y2 jumper must remain installed.
This mode will allow the indoor blower to run at a reduced airflow on the first stage of cooling. A 2-stage thermostat connected to Y2 will then allow the airflow to return to normal rated speed if the call for dehumidification or cooling is not satisfied within the allotted time frame specified by the thermostat. See latest revision of unit installation instructions 2100-721 for more information regarding the Balanced Climate operation.
Electronic Expansion Valve
Operation
This model employs an electronic expansion valve (EEV) which meters the refrigerant to the evaporator. The EEV is made of a stepper motor that is controlled with a step output from the controller. The valve is capable of 480 steps which drives a needle valve that in turn regulates the flow of refrigerant. The EEV allows for tighter control and better capacity management in varying operating conditions than a standard TXV. The EEV system consists of the electronic valve and stator, control board, relay, suction temperature sensor and suction pressure transducer. The pressure transducer and temperature sensor monitor the suction line to provide real time data to the control board so that a real time superheat can be calculated. This then determines the EEV position. The controller is sent to maintain around 13° superheat. The relay is used to activate the EEV system’s controller anytime that the compressor is energized.
WARNING/AVERTISSEMENT
– Exposure to high pressure refrigerant hazard.– This unit is equipped with an electronic expansion valve. In order to fully recover refrigerant or evacuate the system during repairs, be sure to use service tool 2151-021 to manually open the electronic expansion valve or be sure to recover and evacuate from all service ports; suction, liquid, and discharge. – Failure to do so could result in eye injuries and/or refrigerant burns.
EEV Instructions for Vacuuming, Reclaiming and Charging Unit
The electronic expansion valve moves to a closed position when there is no call to control. In order to pull a complete vacuum, fully reclaim the system or charge the unit, connections to both the suction and discharge service ports need to be utilized or the valve needs to be manually opened first. The valve can be opened manually using the magnetic EEV service tool (Bard Part # 2151-021) shown in Figure 2. To do this, remove the EEV stator coil (red color with retaining nut on top), slide the magnetic tool over the shaft where the stator was removed and turn in a clockwise direction to open the valve to the full open position (directional arrows are provided on the tool).Reapply the EEV stator coil and retaining nut once complete. Upon powering the unit back up, the control board will automatically drive the EEV back to the fully shut position. Once the compressor starts, the control board will again modulate the EEV position to control the system superheat.
Troubleshooting the Electronic Expansion Valve
The control board has two status LEDs.
- The green LED should be lit anytime that the board has power and the control is functioning.
- The red LED is to show that an alarm is present.
See Table 1 on page 4 for a guide to know where to start troubleshooting the EEV. Refer to the appropriate unit replacement parts manual for any parts that are needed.
Control Board
Check that the controller is getting 24VAC signal (GO 24VAC Hot and G 24VAC common). Reference unit wiring diagram for proper connections. If 24V is present but the green LED is not lit, replace the controller. If the green LED is now lit but the superheat is still not being maintained, troubleshoot the relay to check that the DI is connected to G; refer to Relay in EEV Control Box below.
Electronic Expansion Valve
Check to see if valve can be moved by manually moving the stepper motor using the EEV service tool shown in Figure 1 (Bard Part # 2151-021). If valve still does not control, check the transducer and thermistor sensors as described on page 5. If sensors are good, replace the valve.
Relay in EEV Control Box
Contacts NO to DI and COM to G must be closed for EEV control to start controlling superheat. Check that the relay is getting 24VAC. Reference unit wiring diagram for proper connections. If 24V is present, measure the resistance between COM and NO; it should be 0 ohms when the relay is getting 24V. If the resistance is out of range, replace the relay.
TABLE 1Electronic Expansion Valve Troubleshooting
Problem | Probable Cause | Troubleshoot |
The green LED is not lit. | Controller not receiving 24VAC signal. | Control Board |
The green LED is lit, but superheat is not being maintained. | The relay is not closing the controller’s DI connection to ground. | Relay |
The red LED is flashing and EEV is not controlling superheat properly (13º superheat). One of the following is likely the fault: | ||
1. Low superheat is detected and the controller is taking steps to protect the system by closing the valve. | Stator is broken or connected incorrectly. | Stator |
Valve is stuck open. | EEV Valve | |
2. Suction temperature sensor error. | Poor connection of sensor or faulty sensor. | Thermistor |
3. Suction pressure transducer error. | Pressure transducer wiring incorrect or faulty transducer. | Transducer |
The red LED is on steady. | The operating parameters have been damaged. | Replace Control Board |
Stator Coil
Disconnect the stator from the valve and the control and measure the resistance of the windings using an electrical tester. The resistance of both windings should be around 40 ohms +/ 10%. The four wire sets that will have resistance between them are: White and red, green and red, yellow and purple, blue and purple. If the resistance falls outside these values, replace the stator.
Transducer Sensor
- Check continuity of all three wires from transducer plug to controller plug. Replace wires if poor connection in any wire.
- Check to ensure wires are correctly connected as follows:Blue wire = pin 1 of controller plug to pin C on transducer plugRed wire = pin 2 of controller plug to pin B on transducer plugBlack wire = pin 3 of controller plug to pin A on transducer plug
- Check that there is 5VDC Nominal between the red and black wires going to the transducer.
- Check the signal voltage between the blue and black wires (0.5-4.5VDC Actual). The following formula and Figure 3 can be used to determine if the transducer’s voltage to pressure ratio is within range. Replace transducer if out of range.
Formula for Tech:(Measured Pressure x .016) + .5 =Expected Transducer Signal Voltage (see Figure 3)
Thermistor Sensor
- Make a visual check for broken wire insulation, broken wires or cracked epoxy material.
- Disconnect 10k ohm NTC thermistor from the EEV control box.
- Use an ohmmeter to measure the resistance between the two connectors. Also use ohmmeter to check for short or open.
- Compare the resistance reading to Table 2. Use sensor ambient temperature. (Tolerance of part is ±10 %.)
- If sensor is out of tolerance, shorted, open or reads very low ohms, it should be replaced.

- Cooling takes precedence over dehumidification. A cooling call cancels dehumidification.
- First stage heating cancels dehumidification.
- If jumper on RLB is set to “1-2 full-time dehumidification”, outputs will energize. This is the factory default setting. If jumper is set to “2-3 occupied dehumidification only”, outputs will be off.
Refrigerant Charge
The correct system R-410A charge is shown on the unit rating plate.Reference Table 9 to validate proper system operation (+2 psig suction, +5 psig discharge) in cooling mode, not dehumidifation mode. However, it is recommended that if incorrect charge is suspected, the system refrigerant be reclaimed, evacuated and charged to the nameplate charge quantity and type.
The nameplate charge quantity is optimized for thermal performance and efficiency of this self-contained package system.The system operating pressures in Table 9 are based upon rated airflow across the evaporator during cooling cycle.Total system charge for these models can be found in Tables 3A and 3B on pages 12 and 13.
