Leave metal jumper in place, connecting 

R & Rc terminals.

If your old thermostat had both 

V and VR wires, stop now and contact a 

qualified contractor for help.

If your old thermostat had separate 

O and B wires, attach the B wire to 

the 

C terminal. If another wire is attached to the C terminal, stop now 

and contact a qualified contractor for help.

If your old thermostat had 

Y1, W1 and W2 wires, stop now and contact 

a qualified contractor for help.

If 

L terminal is used, C terminal wire must be connected (contact a 

contractor if there is no 

C wire).

If 

E and Aux terminals do not each have a wire connected, use a small 

piece of wire to connect them to each other.

Use the Setup and Navigation steps in 12a to set Display Preferences.

Remove metal jumper connecting 

R and Rc only if 

you must connect both 

R and Rc wires.

If your old thermostat had both 

R and RH wires, 

remove metal jumper. Connect the 

R wire to the 

Rc terminal, and the RH wire to the R terminal.

If your old thermostat had only 1 

C or C1 wire, 

connect it to the 

C terminal. If your old thermostat 

had 2 

C or C1 wires, wrap each separately with 

electrical tape and do not connect them.

The number indicates how frequently the system cycles on and off to maintain the set temperature. 
A higher number means the system is on and off for shorter amounts of time, a lower number means 
longer on and off times. When these settings are set to match the system type, the thermostat controls 
temperature more accurately.
