2H/2C: Gas Furnace

1H/1C: Heat Pump without Aux Heat

COMMON REQUIRED.
L ONLY CONNECTED IF HEAT PUMP HAS A FAULT TERMINAL.
SOME HEAT PUMPS USE B RATHER THAN O FOR REVERSING THE VALVE.
DO NOT CONNECT ANY WIRE TO W FOR HEAT PUMP APPLICATIONS! THIS CAN CAUSE HEAT TO RUN CONTINUOUSLY.
M36906A

2H/1C: Heat Pump with Electric Aux Heat

COMMON REQUIRED.
L ONLY CONNECTED IF THE HEAT PUMP HAS A FAULT TERMINAL.
SOME HEAT PUMPS USE B RATHER THAN O FOR REVERSING THE VALVE.
DIFFERENT HEAT PUMP MODELS LABEL THE AUXILIARY HEAT TERMINAL
DIFFERENTLY THAN SHOWN. CONSULT HEAT PUMP WIRING GUIDE.
LOCKOUT OF AUX HEAT ON HIGH OUTDOOR TEMPERATURE CAN BE DONE THROUGH ROUTER/INTERNET CONNECTION AND HOME APP OR WIRE C7089U1006 TO THE TWO “S” TERMINALS.
MOST HEAT PUMPS SHARE THE SAME SET OF HEAT STRIPS FOR AUX AND EM HEAT. IN THOSE CASES E ISN’T USED. THE TH320WF2006 MODEL CAN BE CONFIGURED FOR SEPARATE AUX AND E. IF THIS IS DONE, WIRE ONE SET OF STRIPS TO E TO BE ENERGIZED IN EM HEAT AND A DIFFERENT SET OF STRIPS TO AUX TO BE ENERGIZED IN AUX HEAT.
DO NOT CONNECT ANY WIRE TO W FOR HEAT PUMP APPLICATIONS! THIS CAN CAUSE HEAT TO RUN CONTINUOUSLY.

Dual Fuel, 2H/1C: Heat Pump

COMMON REQUIRED.
L ONLY CONNECTED IF THE HEAT PUMP HAS A FAULT TERMINAL.
SOME HEAT PUMPS USE B RATHER THAN O FOR REVERSING THE VALVE.
THE HEAT PUMP AND FURNACE HAVE SEPARATE BOARDS. WE SHOW THEM TOGETHER TO SIMPLIFY THE DIAGRAM. W IS FROM THE FURNACE BOARD.
BALANCE POINT LOCKOUT CAN BE DONE THROUGH ROUTER/ INTERNET CONNECTION AND HOME APP OR WIRE C7089U1006
TO THE TWO “S” TERMINALS.
DO NOT CONNECT ANY WIRE TO W FOR HEAT PUMP APPLICATIONS THIS CAN CAUSE HEAT TO RUN CONTINUOUSLY.
