HERMOSTAT PPLICATION
To use a single-stage thermostat, turn off power to the furnace,
move the thermostat selection DIP switch to the OFF position.
Turn power back on. Refer to the DIP switch chart in this
manual.
24 V
OLT
The optional usage of a dehumidistat allows the furnace's circu-
lator blower to operate at a slightly lower speed (85% of desired
speed) during a combined thermostat call for cooling and dehu-
midistat call for dehumidification. This can be done through an
independent dehumidistat or through a thermostat's DEHUM ter-
minal (if available). This lower blower speed enhances dehumidi-
fication of the conditioned air as it passes through the AC coil.
For proper function, a dehumidistat applied to this furnace must
operate on 24 VAC and utilize a switch which opens on humidity
rise. Refer to the "Thermostat Wiring Diagrams" figure for
additional wiring details.
ON THE
.
To install/connect a dehumidistat:
1. Turn OFF power to furnace.
2. Secure the dehumidistat neutral wire (typically the white
lead) to the terminal marked "DEHUM" on the furnace
integrated control module.
3. Secure the dehumidistat hot wire (typically the black lead)
to the terminal marked "R" on the furnace integrated
control module.
4. Secure the dehumidistat ground wire (typically the green
lead) to the ground screw on the furnace junction box.
NOTE: Ground wire may not be present on all
dehumidistats.
5. If the condenser is a straight cooling unit, install a
jumper from Y1 to 0 on the furnace board.
6. Turn ON power to furnace.
To enable the dehumidify function on the integrated control
module, set the dehumidification ENABLE DIP switch from
OFF to ON.
Furnace Integrated
Once the switch is set, the dehumidify function is enabled during
Control Module
a combination call for cooling (T-Stat) and dehumidification
(DEHUM-Stat). Refer to the DIP switch chart in the back sec-
tion of this manual.

OSSIL UEL
This furnace can be used in conjunction with a heat pump in a
fossil fuel application. A fossil fuel application refers to a
combined gas furnace and heat pump installation which uses
an outdoor temperature sensor to determine the most cost effi-
cient means of heating (heat pump or gas furnace).
A heat pump thermostat with three stages of heat is required to
properly use a two-stage furnace in conjunction with a heat pump.
Refer to the fossil fuel kit (AFE18-60A) installation instructions
for additional thermostat requirements.
