D Control DIP Switches —
The D Control has 2 DIP
switch blocks. Each DIP switch block has 8 switches and is
labeled either S1 or S2 on the circuit board. See Fig. 8B, 9B
and 10B.
DIP SWITCH BLOCK 1 (S1) — This set of switches offers
the following options for D Control configuration:
Performance Monitor (PM) — Set switch 1 to enable or dis-
able 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 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 energizing 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 selec-
tion 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 out-
put. 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 dehu-
midification mode. The fan speed relay will remain OFF dur-
ing 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 boiler-
less 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 tempera-
ture set by switch 8 below. Select ON for normal operation or
select OFF for boilerless operation.
Boilerless Changeover Temperature — Switch 8 on S1 pro-
vides selection of boilerless changeover temperature set point.
Select OFF for set point of 50 F or select ON for set point
of 40 F.
If switch 8 is set for 50 F, then the compressor will be used
for heating as long as the FP1 is above 50 F. The compressor
will not be used for heating when the FP1 is below 50 F 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. See Fig. 8B, 9B and
10B.
Switches 1 to 3 — These DIP switches provide selection of
Accessory 1 relay options. See Table 6 for DIP switch
combinations.
Switches 4 to 6 — These DIP switches provide selection
of Accessory 2 relay options. See Table 7 for DIP switch
combinations.
NOTE: Low voltage connector may be removed for easy installation.
