44label. For example, flashing code 1 will have an alarm relaycycling code 1. Code 1 indicates the control has not faultedsince the last power-off to power-on sequence.WSHP Open Test Mode — To enter WSHP Open testmode, 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 tohigh, and operates each speed for one minute. Resets to disableon completion.COMPRESSOR TEST — Tests compressor cooling andheating operation. Sequences cooling stage 1 then coolingstage 2 followed by heating stage 2 then reduces capacity toheating stage 1. Operates for 1 minute per step.DEHUMIDIFICATION TEST — Tests dehumidificationmode. Operates for 2 minutes.AUXILIARY HEATING TEST — Tests auxiliary heat.Sequences fan on and enables heating coil for 1 minute.H 2O ECONOMIZER TEST — Tests entering/returningwater loop economizer operation. Sequences fan and openseconomizer water valve for one minute.OPEN VENT DAMPER 100% TEST — Tests outside air(OA) damper operation.PREPOSITION OA DAMPER — Prepositions OA damperactuator to set proper preload.NOTE: The auxiliary heating test, H2O economizer test, openvent damper 100% test, and preposition OA damper featureswill not be visible on the screen unless configured.Once tests are complete, set unit test back to disable. Unit willautomatically reset to disable after 1 hour.Retry Mode — In Retry mode, the status LED will start toflash slowly to signal that the control is trying to recover from aninput fault. The control will stage off the outputs and try to againsatisfy the thermostat used to terminal Y. Once the thermostat in-put calls are satisfied, the control will continue normal operation.NOTE: If 3 consecutive faults occur without satisfying thethermostat input call to terminal Y, the control will go intolockout mode. The last fault causing the lockout is stored inmemory 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 ormode 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 willalways flash a code representing the last fault in memory. Ifthere is no fault in memory, the fault LED will flash code 1 andappear as 1 fast flash alternating with a 10-second pause. SeeTable 17.Table 15 — Complete C Control Current LED Status and Alarm Relay OperationsLEGEND 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 followedby a 10-second pause. This sequence will repeat continually until thefault is cleared.Table 16 — Complete C Control LED Code and Fault DescriptionsLEGENDLED STATUS DESCRIPTION OF OPERATION ALARM RELAYOn Normal Mode OpenNormal Mode with PM Warning Cycle (Closed 5 sec, Open 25 sec)Off Complete C Control is non-functional OpenSlow Flash Fault Retry OpenOver/Under Voltage Shutdown Open (Closed after 15 minutes)Fast Flash Lockout ClosedFlashing Code 1 Test Mode — No fault in memory Cycling Code 1Flashing Code 2 Test Mode — HP Fault in memory Cycling Code 2Flashing Code 3 Test Mode — LP Fault in memory Cycling Code 3Flashing Code 4 Test Mode — FP1 Fault in memory Cycling Code 4Flashing Code 5 Test Mode — FP2 Fault in memory Cycling Code 5Flashing Code 6 Test Mode — CO Fault in memory Cycling Code 6Flashing Code 7 Test Mode — Over/Under shutdown in memory Cycling Code 7Flashing Code 8 Test Mode — PM in memory Cycling Code 8Flashing Code 9 Test Mode — FP1/FP2 swapped fault in memory Cycling Code 9CO — Condensate Overflow LED — Light-Emitting DiodeFP — Freeze Protection LP — Low PressureHP — High Pressure PM — Performance MonitorLED CODE FAULT DESCRIPTION1 No fault in memory There has been no fault since the last power-off to power-on sequence2 High-Pressure Switch HP open instantly3 Low-Pressure Switch LP open for 30 continuous seconds before or during a call (bypassed for first 60 seconds)4 Freeze Protection Coax — FP1 FP1 below temp limit for 30 continuous seconds (bypassed for first 60 seconds of operation)5 Freeze Protection Air Coil — FP2 FP2 below temp limit for 30 continuous seconds (bypassed for first 60 seconds of operation)6 Condensate overflow Sensor overflow (grounded) for 30 continuous seconds7 (Autoreset) Over/Under Voltage Shutdown "R" power supply is <19-vac or >30-vac8 PM Warning Performance monitor Warning has occurred.9 FP1 and FP2 Thermistors are swapped FP1 temperature is higher than FP2 in heating/test mode, or FP2 temperature is higher than FP1 incooling/test mode.FP — Freeze Protection LP — Low PressureHP — High Pressure PM — Performance MonitorLED — Light-Emitting Diode
