Terminal outputs and common wire (c-wire) requirement

The common wire could be labeled “C”, “B” or “X” on the old thermostat. Please refer to the owner’s manual of the old thermostat.

What if I don’t have a common wire (c-wire)?

There are a few options if the application does not have or will not allow the pulling of a common wire (c-wire) through the wall.

Look for an unused wire in the thermostat cable bundle

Do I need a RC/RH jumper?

No jumpers required

Sensi Touch Smart Thermostat has a built in RC/RH jumper, no need to field install a jumper
If you have separate wires to RC and RH terminals (two transformer systems)
— Label the wires RC and RH separately and then clip the jumper wire on the Sensi back plate.

RC/RH jumper location

RC/RH jumper built-in on the back of the thermostat

No jumpers are required when installing the Sensi Touch Smart Thermostat

Wiring – two transformer – conventional single stage or two stage systems

Quick tip: Thermostat wiring does not follow a standardized color code. Take a picture with your smart phone and label thermostat wires before removing old thermostat from the wall.

Wiring – heat pumps single stage or multi-stage systems

Quick tip: Thermostat wiring does not follow a standardized color code. Take a picture with your smart phone and label thermostat wires before removing old thermostat from the wall.

Heat pump wiring exceptions

Separate W2 and E Wires

Both wires will be labeled W/E and attached to the same terminal.

B Terminal Wires

“B” terminal can be used for more than one. Here is the solution to cross.
— If there is a wire on the “O” terminal, label the B wire C
— If there is no wire on the “O” terminal, label the B wire O/B
