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 —
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. 6D and 6E.
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 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 de-
lay 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.
Switches 6, 7, 8 — Not used.
DIP SWITCH BLOCK 2 (S2) — Not used.
Deluxe D Control Accessory Relay Configura-
tions (See Tables 4 and 5) —
sory relay settings are applicable for Deluxe D control 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 configura-
tion, 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.
The Deluxe D

WATER VALVE (SLOW OPENING) — If relay is config-
ured for Water Valve (slow opening), the relay will start 60 sec-
onds prior to starting compressor relay.
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 winterized
with antifreeze.

START-UP
Use the procedure outlined below to initiate proper unit
start-up.
NOTE: This equipment is designed for indoor installation
only.
Operating Limits (See Table 6)
ENVIRONMENT — This equipment is designed for indoor
installation ONLY. Extreme variations in temperature, humidi-
ty and corrosive water or air will adversely affect the unit per-
formance, reliability and service life.
POWER SUPPLY — A voltage variation of ± 10% of name-
plate utilization voltage is acceptable.
UNIT STARTING CONDITIONS — All units start and op-
erate in an ambient of 45 F with entering air at 40 F, entering
water at 20 F.
NOTE: These operating conditions are not normal or continu-
ous operating conditions. It is assumed that start-up is for the
purpose of bringing the building space up to occupancy
temperature.
When the disconnect switch is closed, high voltage is
present in some areas of the electrical panel. Exercise
caution when working with the energized equipment.
