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.
1. Look for an unused wire in the thermostat cable bundle
2. Use the “G” (Fan wire)
3. Install an Emerson Thermostat Common Wire Kit
• Sensi 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 back of the Sensi face plate.
• Sensi Thermostat has a jumper built-in on the back of the thermostat
No jumpers are required when installing the Sensi Smart Thermostat
• Some thermostats will may have additional jumpers installed
• Remove the jumper and label as shown below
