Sensi Smart Thermostat Comparison
Compatibility and common wire (c-wire) requirement
No common wire required• Conventional heating and cooling systemsCommon wire required• Apple HomeKit• Heat only or Cool only (2 wire)• Heat pumpsNot compatible• Millivolt systems*External 24 VAC Transformer is an option• Communicating systems• Line voltage systems• Accessory control
Terminal outputs
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 and need one?
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– Video: Using an extra, unused wire as a common wire2. Use the “G” (Fan wire)– Video: Using a g-wire (fan wire) as a common wire3. Install an Emerson Thermostat Common Wire Kit– Video: Using an Emerson Thermostat Common Wire Kit
Do I need a RC/RH jumper?
No jumpers required
• 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.
RC/RH jumper location
• Sensi Thermostat has a jumper built-in on the back of the thermostat
No jumpers are required when installing the Sensi Smart Thermostat
Heat pump jumper wires
• Some thermostats will may have additional jumpers installed• Remove the jumper and label as shown below
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
Terminal outputs
Note that Y2/* and W2/* are being used for wired humidification or dehumidification, respectively
System configuration
System Compatibility List – Humidity Control

* Note: if the staging on a 2 stage heat or 2 stage cool system can be handled by the furnace/air handler board, that will open up the Y2 or W2 terminal for hum/dehum use.
How to Set Up Humidity Control on the Sensi Thermostat
