ELECTRICAL CONNECTIONS

To use a single-stage thermostat, turn off power to the furnace, move the thermostat selection DIP switch to the OFF position. Set the desired transition time by setting the transition delay DIP switch to the desired ON/OFF position. Turn power back on. Refer to the following figure.

24VOLTDEHUMIDISTATWIRING

The optional usage of a dehumidistat allows the furnace’s circula- tor blower to operate at a slightly lower speed (85% of desired speed) during a combined thermostat call for cooling and dehumi- distat call for dehumidification. This can be done through an inde- pendent dehumidistat or through a thermostat’s DEHUM terminal (if available). This lower blower speed enhances dehumidification of the conditioned air as it passes through theAC 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 wir- ing details.

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.Turn ON power to furnace.

To enable the dehumidify function on the integrated control mod- ule, set the dehumidification ENABLE dipswitch from OFF to ON.

Once the switch is set, the dehumidify function is enabled during a combination call for cooling (T-Stat) and dehumidification (DEHUM- Stat).

WIRING.

The furnace integrated control module is equipped with line voltage accessory terminals for controlling power to an optional field-sup- plied humidifier and/or electronic air cleaner.

The accessory load specifications are as follows:

Humidifier

1.0 Amp maximum at 120 VAC

Electronic Air Cleaner

1.0 Amp maximum at 120 VAC

Turn OFF power to the furnace before installing any accessories. Follow the humidifier or air cleaner manufacturers’ instructions for locating, mounting, grounding, and controlling these accessories. Accessory wiring connections are to be made through the 1/4" quick connect terminals provided on the furnace integrated control module. The humidifier and electronic air cleaner hot terminals are identified as HUM and EAC. The humidifier and electronic air cleaner neutral terminals are identified as NEUTRAL.All field wir- ing must conform to applicable codes. Connections should be made as shown.
