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 BACview 6 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.
H
2
O 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, H
2
O 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 thermostat in-
put 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
always flash a code representing the last fault in memory. If
there is no fault in memory, the fault LED will flash code 1 and
appear as 1 fast flash alternating with a 10-second pause. See
Table 17.
Table 15 — Complete C Control Current LED Status and Alarm Relay Operations
LEGEND 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.
