NOT clip the jumper. To select 10 F as the limit, clip the
jumper.
ALARM RELAY SETTING — Select jumper 1 (JW1-AL2
Dry) to either connect 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.
Deluxe D Control Jumper Settings
WATER COIL FREEZE PROTECTION (FP1) LIMIT
SETTING — Select jumper 3 (JW3-FP1 Low Temp) to
choose FP1 limit of either 30 F or 10 F. To select 30 F as the
limit, DO NOT clip the jumper. To select 10 F 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 either 30 F or 10 F. To select 30 F as the limit, DO
NOT clip the jumper. To select 10 F as the limit, clip the
jumper.
ALARM RELAY SETTING — Select jumper 4 (JW4-AL2
Dry) to either connect 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
input normally opened or closed. To configure for normally
closed operation, DO NOT clip the jumper. To configure for
normally open operation, clip the jumper.
Complete C Control DIP Switches — The Com-
plete C control has 1 DIP (dual in-line package) switch bank
with five switches labeled SW1. See Fig. 15, 17 , 19, and 21.
PERFORMANCE MONITOR (PM) — The PM is a unique
feature that monitors water temperature and will display a warn-
ing when heat pump is beyond typical operating range. Refer to
Control Operation section for detailed information. 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.
SWITCH 3 — Not used.
DDC OUTPUT AT EH2 — Switch 4 provides a selection for
Direct Digital Control (DDC) operation. If set to DDC output
at EH2, the EH2 terminal will continuously output the last
fault code of the controller. If the control is set to EH2 Normal,
then EH2 will operate as standard electric heat output. Set the
switch to ON to set the EH2 to normal. Set the switch to OFF
to set the DDC output at EH2.
FACTORY SETTING — Switch 5 is set to ON. Do not
change the switch to OFF unless instructed to do so by the
factory.
Deluxe D Control DIP Switches — The Deluxe D
control has 2 DIP (dual in-line package) switch banks. Each
bank has 8 switches and is labeled either S1 or S2 on the cir-
cuit board. See Fig. 16, 18, 20, 22, and 23.
DIP SWITCH BANK 1 (S1) — This set of switches offers
the following options for Deluxe D control configuration:
Performance Monitor (PM)
— The PM is a unique feature
that monitors water temperature and will display a warning
when heat pump is beyond typical operating range. 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 en-
able or disable compressor relay staging operation. The com-
pressor 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 mas-
ter/slave applications. In master/slave applications, each com-
pressor 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 se-
lection 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 thermostats.
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 reversing valve (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 thermostats with O output. Select OFF for
thermostats with B output.
Dehumidification Fan Mode
— Switch 5 provides selection
of normal or dehumidification fan mode. Select OFF for
dehumidification 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.
Output
— Switch 6 provides selection for DDC operation. If
set to DDC output at EH2, the EH2 terminal will continuously
output the last fault code of the controller. If the control is set to
EH2 normal, then the EH2 will operate as standard electric
heat output. Set the switch to ON to set the EH2 to normal. Set
the switch to OFF to set the DDC output at EH2.
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.
IMPORTANT: Jumpers and DIP switches should only
be clipped when power to control board has been turned
off.
