initiate a 5 to 80 second random start delay and a 5-minute anti-
short cycle protection time delay. After both delays are
complete, the compressor is energized.
NOTE: On all subsequent compressor calls the random start
delay is omitted.
HEATING STAGE 2 — To enter Stage 2 mode, terminal W
is active (Y is already active). Also, the G terminal must be
active or the W terminal is disregarded. The compressor relay
will remain on and EH1 (emergency heat) is immediately
turned on. EH2 will turn on after 10 minutes of continual
stage 2 demand.
NOTE: EH2 will not turn on (or if on, will turn off) if FP1
(freeze protection) temperature is greater than 45 F and FP2 is
greater than 110 F.
EMERGENCY HEAT — In emergency heat (EH) mode, ter-
minal W is active while terminal Y is not. Terminal G must be
active or the W terminal is disregarded. EH1 is immediately
turned on. EH2 will turn on after 5 minutes of continual emer-
gency heat demand.
Units with Aquazone™ Deluxe D Control
STANDBY/FAN ONLY — The compressor will be off. The
Fan Enable, Fan Speed, and reversing valve (RV) relays will be
on if inputs are present. If there is a Fan 1 demand, the Fan
Enable will immediately turn on. If there is a Fan 2 demand,
the Fan Enable and Fan Speed will immediately turn on.
NOTE: DIP switch 5 on S1 does not have an effect upon Fan 1
and Fan 2 outputs.
HEATING STAGE 1 — In Heating Stage 1 mode, the Fan
Enable and Compressor relays are turned on immediately.
Once the demand is removed, the relays are turned off and the
control reverts to Standby mode. If there is a master/slave or
dual compressor application, all compressor relays and related
functions will operate per their associated DIP switch 2 setting
on S1.
HEATING STAGE 2 — In Heating Stage 2 mode, the Fan
Enable and Compressor relays are remain on. The Fan Speed
relay is turned on immediately and turned off immediately
once the demand is removed. The control reverts to Heating
Stage 1 mode. If there is a master/slave or dual compressor
application, all compressor relays and related functions will
operate per their associated DIP switch 2 setting on S1.
HEATING STAGE 3 — In Heating Stage 3 mode, the Fan
Enable, Fan Speed and Compressor relays remain on. The EH1
output is turned on immediately. With continuing Heat Stage 3
demand, EH2 will turn on after 10 minutes. EH1 and EH2 are
turned off immediately when the Heating Stage 3 demand is re-
moved. The control reverts to Heating Stage 2 mode.
Output EH2 will be off if FP1 is greater than 45 F AND FP2
(when shorted) is greater than 110 F during Heating Stage 3
mode. This condition will have a 30-second recognition time.
Also, during Heating Stage 3 mode, EH1, EH2, Fan Enable,
and Fan Speed will be ON if G input is not active.
EMERGENCY HEAT — In Emergency Heat mode, the Fan
Enable and Fan Speed relays are turned on. The EH1 output is
turned on immediately. With continuing Emergency Heat de-
mand, EH2 will turn on after 5 minutes. Fan Enable and Fan
Speed relays are turned off after a 60-second delay. The control
reverts to Standby mode.
Output EH1, EH2, Fan Enable, and Fan Speed will be ON if
the G input is not active during Emergency Heat mode.
COOLING STAGE 1 — In Cooling Stage 1 mode, the Fan
Enable, compressor and RV relays are turned on immediately.
If configured as stage 2 (DIP switch set to OFF) then the com-
pressor and fan will not turn on until there is a stage 2 demand.
The Fan Enable and compressor relays are turned off immedi-
ately when the Cooling Stage 1 demand is removed. The con-
trol 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 func-
tions 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
relay 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 ap-
plication, 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.
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. 9.
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 10-12. 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.
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 on
the and appear as 1 fast flash alternating with a 10-second
pause. See Table 12.
