COMMON REQUIRED.
L ONLY CONNECTED IF HEAT PUMP HAS A FAULT TERMINAL.
SOME HEAT PUMPS USE B RATHER THAN O FOR REVERSING VALVE.
THE HEAT PUMP AND FURNACE HAVE SEPARATE BOARDS. WE SHOW
THEM TOGETHER TO SIMPLIFY THE DIAGRAM. W IS FROM THE
FURNACE BOARD.
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.
DO NOT CONNECT ANY WIRE TO W FOR HEAT PUMP APPLICATIONS!
THIS CAN CAUSE HEAT TO RUN CONTINUOUSLY.
