A1. If any of the original equipment wire is replaced use wire rated for 105°C.2. Use only copper wire between the disconnect switch and the furnace junction box (JB).3. This wire must be connected to furnace sheet metal for control to prove flame.4. Symbols are electrical representation only.5. Solid lines inside PCB are printed circuit board conductors and are not included in legend.6. Replace only with a 3 amp fuse.7. Inductor is used with 3/4 hp and 1 hp ECM Blower motors.8. Factory connected when (LGPS) not used.9. Blower off-delay, gas heating selections are (90, 120, 150, 180) seconds, cooling or heat pump90 seconds or 5 seconds when dehumidify call is active.10. Ignition lockout will occur after four consecutive unsuccessful trials for ignition. Control willauto-reset after three hours.11. Any of the 5 wires shown within the NEUTRAL L2 box can be connected to any terminal within the box.12. Blower motor (BLWM) and Inducer motor (IDM) are locked-rotor overload protected by redundantelectronic control circuits.A/C Air Conditioning (Adjustable Airflow -CFM)ACR Air Conditioning Relay, SPST (N.O.)ACRDJ Air Conditioning Relay Defeat JumperBLWM Blower Motor (ECM)CF Continuous Fan (Adjustable Airflow -CFM)COMMR Communication Relay, SPDTCPU Microprocessor / CircuitryDHUM DHUM Connection (24VAC )EAC-1 Electronic Air Cleaner Connection(115VAC 1.0 Amp Max.)EAC-2 Electronic Air Cleaner Connection (Common)FRS Flame Rollout Switch, Man.

See Thermidistatt, Zone Controller,thermostat, or controller manufacturer’s instructions forproper connection.CAUTION! 2. Humidifier (HUM)Connect an accessory 24 VAC, 0.5 amp maximumhumidifier (if used) to the 1/4--in. male quick--connectHUM terminal and COM--24V screw terminal on thecontrol board thermostat strip. The HUM terminal isenergized when blower is energized in heating. (See Fig.23 and 33.)Step 8 —Removal of Existing Furnaces fromCommon Vent SystemsWhen an existing Category I furnace is removed or replaced, theoriginal venting system may no longer be sized to properly ventthe remaining attached appliances. An improperly sized CategoryI venting system could cause the formation of condensate in thefurnace and vent, leakage of condensate and combustionproducts, spillage of combustion products into the living space,etc.58UVB
