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.
