800SA/801SA: Installation, Start–Up, Operating and Service and Maintenance Instructions

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

The 24-v circuit contains an automotive-type, 3-amp. fuse located on the

control. Any direct shorts during installation, service, or maintenance

could cause this fuse to blow. If fuse replacement is required, use ONLY

a 3-amp. fuse of identical size.

ACCESSORIES

1. Electronic Air Cleaner (EAC)

Connect an accessory Electronic Air Cleaner (if used) using 1/4-in

female quick connect terminals to the two male 1/4-in

quick-connect terminals on the control board marked EAC-1 and

EAC-2. The terminals are rated for 115 VAC, 1.0 amps maximum

and are energized during blower motor operation (see

Fig. 28

2. Humidifier (HUM)

Connect an accessory 24 VAC, 0.5 amp. maximum humidifier (if

used) to the 1/4-in male quick-connect HUM terminal and

COM-24V screw terminal on the control board thermostat strip.

The HUM terminal is energized when the pressure switch closes

during a call for heat (see

Fig. 28

NOTE:

DO NOT connect furnace control HUM terminal to HUM

(humidifier) terminal on Thermidistat

, Zone Controller or similar

device. See Thermidistat, Zone Controller, thermostat, or controller

manufacturer’s instructions for proper connection.
