compressor application, all compressor relays and related func- tions will track with their associated DIP switch 2 on S1.

NIGHT LOW LIMIT (NLL) STAGED HEATING — In NLL staged Heating mode, the override (OVR) input becomes active and is recognized as a call for heating and the control will immediately go into a Heating Stage 1 mode. With an ad- ditional 30 minutes of NLL demand, the control will go into Heating Stage 2 mode. With another additional 30 minutes of NLL demand, the control will go into Heating Stage 3 mode.

Units with HWR Option

FAN ONLY — A (G) call from the thermostat to the (G) terminal of the Deluxe D control board will bring the unit on in fan only mode.

COOLING STAGE 1 — A simultaneous call from (G), (Y1), and (O) to the (G), (Y1), (O/W2) terminals of the Deluxe D control board will bring the unit on in 1st Stage Cooling.

COOLING STAGE 2 — A simultaneous call from (G), (Y1), (Y2), and (O) to the (G), (Y1), (Y2), and (O/W2) ter- minals of the Deluxe D control board will bring the unit on in Cooling Stage 2. When the call is satisfied at the thermo- stat the unit will continue to run in Cooling Stage 1 until the Cooling Stage 1 call is removed or satisfied, shutting down the unit.

NOTE: Not all units have two-stage cooling functionality.

HEATING STAGE 1 — A simultaneous call from (G) and (Y1) to the (G) and (Y1) terminals of the Deluxe D control board will bring the unit on in Heating Stage 1.

HEATING STAGE 2 — A simultaneous call from (G), (Y1), and (Y2) to the (G), (Y1), and (Y2) terminals of the Deluxe D control board will bring the unit on in Heating Stage 2. When the call is satisfied at the thermostat the unit will continue to run in Heating Stage 1 until the call is removed or satisfied, shutting down the unit.

NOTE: Not all units have two-stage heating functionality.

REHEAT MODE — A call from the humidistat/dehumid- istat to the (H) terminal of the Deluxe D control board will bring the unit on in Reheat Mode if there is no call for cool- ing at the thermostat. When the humidistat/dehumidistat call is removed or satisfied the unit will shut down.

NOTE: Cooling always overrides Reheat Mode. In the Cool- ing mode, the unit cools and dehumidifies. If the cooling thermostat is satisfied but there is still a call for dehumidifi- cation, the unit will continue to operate in Reheat Mode.

SYSTEM TEST

System testing provides the ability to check the control operation. The control enters a 20-minute Test mode by mo- mentarily shorting the test pins. All time delays are increased 15 times. See Fig. 19-22.

Test Mode — To enter Test mode on Complete C or Deluxe D controls, cycle the power 3 times within 60 seconds. The LED (light-emitting diode) will flash a code representing the last fault when entering the Test mode. The alarm relay will also power on and off during Test mode. See Tables 27 and 28. To exit Test mode, short the terminals for 3 seconds or cycle the power 3 times within 60 seconds.

NOTE: Deluxe D Control has a flashing code and alarm relay cycling code that will both have the same numerical label. For example, flashing code 1 will have an alarm relay cycling code 1. Code 1 indicates the control has not faulted since the last power off to power on sequence.

Retry Mode — In Retry mode, the status LED will start to flash slowly to signal that the control is trying to recover from an input fault. The control will stage off the outputs and try to again satisfy the thermostat used to terminal Y. Once the ther- mostat input calls are satisfied, the control will continue normal operation.

NOTE: If 3 consecutive faults occur without satisfying the thermostat input call to terminal Y, the control will go into lockout mode. The last fault causing the lockout is stored in memory and can be viewed by entering Test mode.

NOTES:

1.Slow flash is 1 flash every 2 seconds.

2.Fast flash is 2 flashes every 1 second.

3.EXAMPLE: “Flashing Code 2” is represented by 2 fast flashes followed by a 10-second pause. This sequence will repeat continually until the fault is cleared.
