FIELD SELECTABLE INPUTS
Jumpers and DIP (dual in-line package) switches on the
control board are used to customize unit operation and can be
configured in the field.
Complete C Control Jumper Settings (See
Fig. 27)
WATER COIL FREEZE PROTECTION (FP1) LIMIT
SETTING — Select jumper 3, (JW3-FP1 Low Temp) to
choose FP1 limit of –12.2 C or –1.1 C. To select –1.1 C as the
limit, DO NOT clip the jumper. To select –12.2 C as the limit,
clip the jumper.
AIR COIL FREEZE PROTECTION (FP2) LIMIT SET-
TING — Select jumper 2 (JW2-FP2 Low Temp) to choose
FP2 limit of –12.2 C or –1.1 C. To select –1.1 C as the limit,
DO NOT clip the jumper. To select –12.2 C as the limit, clip
the jumper.
ALARM RELAY SETTING — Select jumper 1 (JW1-AL2
Dry) for connecting alarm relay terminal (AL2) to 24 vac (R) or
to remain as a dry contact (no connection). To connect AL2 to
R, do not clip the jumper. To set as dry contact, clip the jumper.
Complete C Control DIP Switches —
The Com-
plete C control has 1 DIP switch block with five switches. See
Fig. 27.
PERFORMANCE MONITOR (PM) — DIP switch 1 will
enable or disable this feature. To enable the PM, set the switch
to ON. To disable the PM, set the switch to OFF.
STAGE 2 — DIP switch 2 will enable or disable compressor
delay. Set DIP switch to OFF for stage 2 in which the compres-
sor will have a 3-second delay before energizing.
NOTE: The alarm relay will not cycle during Test mode if
switch is set to OFF, stage 2.
DIP SWITCH 3 — not used.
DIP SWITCH 4 — not used.
DIP SWITCH 5 — DIP switch 5 is used to initiate 1 or 3 tries
for the FP1 fault. If water freeze protection for the water coil
then DIP switch 5 can be set to lock out on the FP1 fault after
one try.
Deluxe D Control Jumper Settings (See
Fig. 28)
WATER COIL FREEZE PROTECTION (FP1) LIMIT
SETTING — Select jumper 3, (JW3-FP1 Low Temp) to
choose FP1 limit of –12.2 C or –1.1 C. To select –1.1 C as the
limit, DO NOT clip the jumper. To select –12.2 C as the limit,
clip the jumper.
AIR COIL FREEZE PROTECTION (FP2) LIMIT SET-
TING — Select jumper 2 (JW2-FP2 Low Temp) to choose
FP2 limit of –12.2 C or –1.1 C. To select –1.1 C as the limit,
DO NOT clip the jumper. To select –12.2 C as the limit, clip
the jumper.
ALARM RELAY SETTING — Select jumper 4 (JW4-AL2
Dry) for connecting alarm relay terminal (AL2) to 24 vac (R) or
to remain as a dry contact (no connection). To connect AL2 to
R, do not clip the jumper. To set as dry contact, clip the jumper.
LOW PRESSURE SETTING — The Deluxe D Control can
be configured for Low Pressure Setting (LP). Select jumper 1
(JW1-LP Norm Open) for choosing between low pressure in-
put normally opened or closed. To configure for normally
closed operation, do not clip the jumper. To configure for nor-
mally open operation, clip the jumper.
Deluxe D Control DIP Switches —
The Deluxe 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. 28.
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 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 Deluxe D controls) or in master/slave ap-
plications. 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 ener-
gizing 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 boil-
erless 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 10.0 C or select ON for set point
of 4.4 C.
If switch 8 is set for 10.0 C, then the compressor will be
used for heating as long as the FP1 is above 10.0 C. The com-
pressor will not be used for heating when the FP1 is below
10.0 C and the compressor will operate 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 termi-
nals 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. 28.
Switches 1 to 3 — These DIP switches provide selection of
Accessory 1 relay options. See Table 13 for DIP switch
combinations.
Switches 4 to 6 — These DIP switches provide selection
of Accessory 2 relay options. See Table 14 for DIP switch
combinations.
IMPORTANT: Jumpers and DIP switches should only be
clipped when power to control board has been turned off.
