Fossil Fuel Applications

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 when to run the heat pump 

or gas furnace.
For non-communicating single stage heat pump installations a 

fossil fuel kit can be used.  Follow the wiring guidelines in the 

fossil fuel kit installation instructions.  All furnace connections 

must be made to the furnace integrated control module and 

the “FURNACE” terminal strip on the fossil fuel control board. 

For Fossil Fuel systems the heat pump is given priority 

when a compressor balance point lockout condition is 

not present.  Transitions from primary heat pump heat

-

ing to backup gas heating will result in full capacity 

operation during the first thermostat call. The furnace 

PCB algorithms will then continuously adjust the stage 

times or the percent capacity after the initial call in an 

attempt to satisfy the thermostat at the target runtime.

Automatic Fossil Fuel Adjustment: If both compressor 

balance point and backup heat balance point lockouts 

are not present, the furnace algorithms will determine 

if the heat pump is capable of satisfying the thermostat 

in the selected target runtime.  If the heat pump is not 

capable of this it will be locked out until the furnace 

can satisfy the thermostat, under the target runtime, 

while running completely in low stage.  At that point, 

an attempt will be given to the heat pump and a deci

-

sion made to keep using gas heat or to transition back 

to the heat pump.

WARNING

The accessory load specifications are as follows:

EAC

1.0 Amp maximum at 120 VAC

The furnace integrated control module is equipped with a 

line voltage  accessory terminal for controlling power to an 

optional field supplied electronic air cleaner or any device 

required to operate in parallel with a circulating fan 

demand.

To connect an electronic air cleaner using the line volt

-

age EAC terminal:

• 

Turn OFF power to the furnace before installing any 

accessories. 

• 

Follow the air cleaner manufacturers’ instructions 

for locating, mounting, grounding, and controlling 

accessories.  Utilize 1/4” quick connect terminals to 

make accessory wiring connections to the furnace 

integrated control module.

• 

Connect the hot terminal utilized for accessory operation 

to the EAC terminal and the neutral side of power to 

NEUTRAL bus on the integrated furnace control or the 

neutral connection in the furnace junction box. 

• 

All field wiring must conform to applicable codes.

• 

Connections should be made as shown.

• 

If it is necessary for the installer to supply additional line 

voltage wiring to the inside of the furnace, the wiring 

must conform to all local codes, and have a minimum 

temperature rating of 105°C.  

• 

All line voltage wire splices must be made inside the 

furnace junction box.

Auxiliary Alarm Switch: 

The control is equipped with a 24VAC Aux Alarm to be 

used for a condensate switch install (designated by 

“Condensate” on the control).  

These contacts could 

also be used with compatible CO

2

 sensors or Fire Alarms.  

By default, an AUX switch is normally closed and opens 

when the water level in the evaporator coil base pan 

reaches an undesirable level. The control will respond 

by turning off the outdoor condensing unit and display 

EEd. If the AUX switch is detected closed for 30 seconds, 

normal operation resumes and error messages are no 

longer displayed.
