T6 Pro Smart Wiring Diagrams
ADDENDUM
WIRING DIAGRAMS
Heat only: Gas or Oil Furnace
COMMON REQUIRED.
G USED FOR INDEPENDENT FAN CONTROL ONLY. MOST HEAT ONLY, GAS, OR OIL FORCED
AIR SYSTEMS DO NOT USE A FAN
(G) WIRE.
M36897B
Cool only
COMMON REQUIRED.
1H/1C: Gas Furnace 2H/1C: Gas Furnace 2 Transformer System, 1H/1C: Oil Furnace
2 Transformer System, Hot Water Heat with Air-Conditioning (or Hot Water Coil)
Hot Water Boiler, Heat Only
Hot Water Heat with Power Open Zone Valve Hot Water Heat with Power Open/Power Closed, Series 20 Zone Valve.
COMMON WIRE TO THERMOSTAT REQUIRED ON T6 SMART MODELS.
OPTIONAL ON T1, T3, T4, AND NON-WI-FI T6 MODELS.
THE THERMOSTAT MUST BE CONFIGURED FOR RADIANT HEAT WITH 0 COOL STAGES.
M38661
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.
M36907B
2H/2C: 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.
M36908B
3H/2C 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.
DO NOT CONNECT ANY WIRE TO W FOR HEAT PUMP APPLICATIONS! THIS CAN CAUSE
HEAT TO RUN CONTINUOUSLY.
MOST HEAT PUMPS SHARE THE SAME SET OF HEAT STRIPS FOR AUX AND EM HEAT. IN
THOSE CASES E ISN’T USED. THE TH6320WF2006 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.
M36909B
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.
M36910C
Dual Fuel, 3H/2C: 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.
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 THE HEAT PUMP
APPLICATIONS! THIS CAN CAUSE HEAT TO RUN CONTINUOUSLY.
