O/13 Thermostat Type -- Switch 4 provides selectiou for heat
pump O/B thermostats, O is cooliug output. B is heating out-
put. Select ON for thermostats with O output. Select OFF for
thermostats with B output.
Dehumidificatiou Fau Mode -- Switch 5 provides selection
of uonnal or dehumidificatiou 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 -- Switch 6 provides selection for DDC operation. If
set to DDC output fit EH2, the EH2 terminal will continuously
output file last fault code of the controllel: If the control is set to
EH2 normal, then the EH2 will operate as stml&trd electric
heat output. Set the switch to ON to set the EH2 to normal. Set
the switch to OFF to set the DDC output fit EH2.
Boilerless Operation --Switch 7 provides selection of boiler-
less operation and works in conjunction with switch 8. In boil-
erless operation mode, only the compressor is used for heating
when FPI is above the boilerless changeover temperature set
by switch 8 below. Select ON for normffl operation or select
OFF for boilerless operation.
Boilerless Changeover Temperature -- Switch 8 on SI pro-
vides selection of boilefless changeover temperature set point.
Select OFF for set point of 50 F or select ON for set point of
4O E
If switch 8 is set for 50 F. then the compressor will be used
for heating as long as the FPI is above 50 E The complessor
will not be used for heating when the FPI is below 50 F and the
compressor will operates in emergency heat mode, staging on
EH 1 and EH2 to provide heat. If a thermffl switch is being used
instead of the EPI thermistol: only the compressor will be used
for heating mode when the FPI terminfds me closed. If the FPI
terminals are open, the compressor is not used and the control
goes into emergency heat mode.
DIP SWITCH BANK 2 ($2) -- This set of DIP switches is
used to configure accessory relay options. See Fig. 4.
Switches 1 to 3 -- These DIP switches provide selection of
Accessory 1 relay options. See Table 1 for DIP switch
combinations.
Switches 4 to 6 -- These DIP switches provide selection of
Accessory 2 relay options. See Table 2 for DIP switch
combinations.
Auto Dehumidification Mode or High Fan Mode -- Switch 7
provides selection of auto dehumidification fan mode or high
fan mode. hi 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 terminffl H is active. Set the switch to ON for auto
dehumidification fan mode or to OFF for high fan mode.
Factory Setting -- Switch 8 is set to ON. Do not chmlge the
switch to OFF unless instructed to do so by the factory.

Deluxe D Control Accessory Relay Configura-
tions -- The following accessory relay settings fire applica-
ble for Deluxe D control:
CYCLE WITH FAN --In this configuration, the accessory
relay 1 will be ON rely time the Fro1 Enable relay is on.
CYCLE WITH COMPRESSOR -- In this configuration, the
accessory relay 2 will be ON any time file Compressor relay is
OU.
DIGITAL NIGHT SET BACK (NSB) --In this configura-
tion, the relay will be ON if the NSB input is comlected to
ground C.
NOTE: If there are no relays configured for digital NSB, then
the NSB and OVR inputs am automaticfdly configured for
mechmfical operation. See the Mechmfical Night Set Back sec-
tion on page 16.
WATER VALVE (Slow Opening) -- If relay is configured for
Water Vfflve (slow opening), the relay will stm't 60 seconds
prior to starting compressor relay.
OUTSIDE AIR DAMPER (OAD) --If relay is configured for
OAD, the relay will normfdly be ON any time the Fan Enable
relay is energized. The relay will not start for 30 minutes fol-
lowing a return to normal mode fi_m NSB, when NSB is no
longer connected to ground C. After 30 minutes, the relay will
stfut if the Fan Enable is set to ON.
HUMIDITY CONTROL -- A separate humidistat will allow
the unit to dehumidify once the heating call is satisfied. Some
integrated thermostats may be reconfigured to ffllow dehumidi-
fication in heating. See Fig. 4 for typical humidistat wiring. See
below for Deluxe D DIP switch settings and reheat logic.

Humidistat -- The humidistat energizes a contact when the
humidity of the space rises or falls. See Table 3. A reheat coil
(water coil located after the evaporator coil) will be modulated
by a motorized vfdve enabled by the ACCI relay to bring the
supply air to neutral conditions.
