operate if the loop pump status is off and therefore the WSHP compressor will not run.

COMPLETE C AND DELUXE D BOARD

SYSTEM TEST

System testing provides the ability to check the control operation. The control enters a 20-minute Test mode by momentarily shorting the test pins. All time delays are in- creased 15 times. See Fig. 13-17.

Test Mode — To enter Test mode on Complete C or Deluxe D controls, cycle the fan 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 26-28. To exit Test mode, short the terminals for 3 seconds or cycle the fan 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.

WSHP Open Test Mode — To enter WSHP Open test mode, navigate from the BACview6 home screen to the config- uration screen. Choose the service screen and enable unit test. The controller will then test the following:

FAN TEST — Tests all fan speeds, sequences fan from low to high, and operates each speed for one minute. Resets to disable on completion.

COMPRESSOR TEST — Tests compressor cooling and heating operation. Sequences cooling stage 1 then cooling stage 2 followed by heating stage 2 then reduces capacity to heating stage 1. Operates for 1 minute per step.

DEHUMIDIFICATION TEST — Tests dehumidification mode. Operates for 2 minutes.

AUXILIARY HEATING TEST — Tests auxiliary heat. Sequences fan on and enables heating coil for 1 minute.

H2O ECONOMIZER TEST — Tests entering/returning water loop economizer operation. Sequences fan and opens economizer water valve for one minute.

OPEN VENT DAMPER 100% TEST — Tests outside air (OA) damper operation.

PREPOSITION OA DAMPER — Prepositions OA damper actuator to set proper preload.

NOTE: The auxiliary heating test, H2O economizer test, open vent damper 100% test, and preposition OA damper features will not be visible on the screen unless configured.

Once tests are complete, set unit test back to disable. Unit will automatically reset to disable after 1 hour.

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.

Aquazone™ Deluxe D Control LED Indica-

tors — There are 3 LED indicators on the Deluxe D control:

STATUS LED — Status LED indicates the current status or mode of the Deluxe D control. The Status LED light is green.

TEST LED — Test LED will be activated any time the De- luxe D control is in test mode. The Test LED light is yellow.

FAULT LED — Fault LED light is red. The fault LED will al- ways flash a code representing the last fault in memory. If there is no fault in memory, the fault LED will flash code 1 on the and appear as 1 fast flash alternating with a 10-second pause. See Table 28.
