SOME HEAT PUMPS USE B RATHER THAN O FOR REVERSING 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.
