5.4 - Deluxe D control DIP switches
The Deluxe D control has 2 DIP switch blocks. Each DIP
switch block has 8 switches and is labelled either S1 or S2 on
the circuit board (see Figs. 12 and 14).
DIP switch block 1 (S1) - This set of switches offers the
following options for Deluxe D control configuration:
Performance Monitor (PM): Set switch 1 to enable or disable
performance monitor. To enable the PM, set the switch to ON.
To disable the PM, set the switch to OFF.
Compressor relay staging operation: Switch 2 will enable or
disable compressor relay staging operation. The compressor
relay can be set to turn on with stage 1 or stage 2 call from the
thermostat. This setting is used with dual stage units (units with
2 compressors and 2 Deluxe D controls) or in master/slave
applications. In master/slave applications, each compressor and
fan will stage according to its switch 2 setting. If switch is set to
stage 2, the compressor will have a 3-second delay before
energising during stage 2 demand.
NOTE: If DIP switch is set for stage 2, the alarm relay will
not cycle during Test mode.
Heating/cooling thermostat type: Switch 3 provides selection
of thermostat type. Heat pump or heat/cool thermostats can be
selected. Select OFF for heat/cool thermostats. When in heat/
cool mode, Y1 is used for cooling stage 1, Y2 is used for
cooling stage 2, W1 is used for heating stage 1 and O/W2 is
used for heating stage 2. Select ON for heat pump applications.
In heat pump mode, Y1 used is for compressor stage 1, Y2 is
used for compressor stage 2, W1 is used for heating stage 3 or
emergency heat, and O/W2 is used for RV (heating or cooling)
depending upon switch 4 setting.
O/B thermostat type: Switch 4 provides selection for heat pump
O/B thermostats. O is cooling output. B is heating output. Select
ON for heat pumps with O output. Select OFF for heat pumps
with B output.
Dehumidification fan mode: Switch 5 provides selection of
normal or dehumidification fan mode. Select OFF for dehumidifi-
cation mode. The fan speed relay will remain OFF during cooling
stage 2. Select ON for normal mode. The fan speed relay will
turn on during cooling stage 2 in normal mode.
Switch 6: Not used.
Boilerless operation: Switch 7 provides selection of boilerless
operation and works in conjunction with switch 8. In boilerless
operation mode, only the compressor is used for heating when
FP1 is above the boilerless changeover temperature set by switch
8 below. Select ON for normal operation or select OFF for
boilerless operation.
Boilerless changeover temperature: Switch 8 on S1 provides
selection of boilerless changeover temperature set point. Select
OFF for set point of 10
°
C or select ON for set point of 4.4
°
C.
If switch 8 is set for 10
°
C, then the compressor will be used for
heating as long as the FP1 is above 10
°
C. The compressor will
not be used for heating when the FP1 is below 10
°
C and the
compressor will operates in emergency heat mode, staging on
EH1 and EH2 to provide heat. If a thermal switch is being used
instead of the FP1 thermistor, only the compressor will be used
for heating mode when the FP1 terminals are closed. If the FP1
terminals are open, the compressor is not used and the control
goes into emergency heat mode.
DIP switch block 2 (S2) - This set of DIP switches is used to
configure accessory relay options:
Switches 1 to 3: These DIP switches provide selection of acces-
sory 1 relay options. See Table 6 for DIP switch combinations.
Switches 4 to 6: These DIP switches provide selection of acces-
sory 2 relay options. See Table 7 for DIP switch combinations.

Auto dehumidification mode or high fan mode: Switch 7 pro-
vides selection of auto dehumidification fan mode or high fan
mode. In auto dehumidification fan mode the fan speed relay will
remain off during cooling stage 2 if terminal H is active. In high
fan mode, the fan enable and fan speed relays will turn on when
terminal H is active. Set the switch to ON for auto dehumidifica-
tion fan mode or to OFF for high fan mode.
Switch 8: Not used.
5.5 - Deluxe D control accessory relay configurations
The following accessory relay settings are applicable for both
Deluxe D controls only:
Cycle with compressor - In this configuration, the relay will be
ON any time the compressor relay is on.
Digital night setback (NSB) - In this configuration, the relay
will be ON if the NSB input is connected to ground C.
NOTE: If there are no relays configured for digital NSB, then
the NSB and OVR inputs are automatically configured for
mechanical operation.
Mechanical night setback - When NSB input is connected to
ground C, all thermostat inputs are ignored. A thermostat setback
heating call will then be connected to the OVR input. If OVR
input becomes active, then the Deluxe D control will enter night
low limit (NLL) staged heating mode. The NLL staged heating
mode will then provide heating during the NSB period.
5.6 - Water valve (slow opening)
If relay is configured for water valve (slow opening), the relay
will start 60 seconds prior to starting compressor relay.
CAUTION: To avoid equipment damage, DO NOT leave
system filled in a building without heat during the winter
unless anti-freeze is added to system water. Condenser coils
never fully drain by themselves and will freeze unless
winterised with anti-freeze.
