immediately when the Cooling Stage 1 demand is removed.
The control reverts to Standby mode. The RV relay remains on
until there is a heating demand. If there is a master/slave or
dual compressor application, all compressor relays and related
functions will track with their associated DIP switch 2 on S1.
COOLING STAGE 2 — In Cooling Stage 2 mode, the fan
enable, compressor and RV relays remain on. The fan speed re-
lay is turned on immediately and turned off once the Cooling
Stage 2 demand is removed. The control reverts to Cooling
Stage 1 mode. If there is a master/slave or dual compressor
application, all compressor relays and related functions 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
additional 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.
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 reduced
by a factor of 15.
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 12-14. To
exit Test mode, short the terminals for 3 seconds or cycle the
power 3 times within 60 seconds.
NOTE: The 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 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 14.
Table 12 — 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.
