Heating: 1 and 2 Stages (W1, W2) Cooling: 1 and 2 Stages (Y1, Y2) Heat Pump: 1 and 2 stage with Aux or Emergency Heat (O/B, Aux/E) Fan Control: G Humidification and Dehumidification Power: C (required), RH, RC Converts to Fahrenheit or Celsius Check Your Compatibility Size ...
The circuitry can include one or more field effect transistors adapted and arranged so as to open or close an electrical connections between the control and power wires, thereby turning on or off the associated HVAC function. According to some embodiments, the Rc and Rh terminals are permanently...
If you have separate heating and air conditioning systems, you might have separate Rh and Rc wires that come out of the wall and are connected to your system. These are not jumper wires, and you can insert the Rc wire into the Rc connector and the Rh wire into the Rh connector. Tip...

K OTHER Combines Y and F wires on some thermostats. L or A STATUS Light terminal that indicates device operational status. R or V POWER Powers the HVAC system. An HVAC system might have separate Rc and Rh terminals. Rc POWER Power for the cooling system. Rh POWER Power for the heating ...
Remove any jumper wires (wires that connect to two terminals), like Rh to Rc. Using the wire labels provided, label each wire based on where it’s connected to the thermostat terminal—NOT based on the color of the wire. Disconnect the wires and unscrew the old thermostat base. Be carefu...
1). Attach theRedwire to the R terminal for 24VPower– or to the RC terminal if that is where it was on the old thermostat. 2). Attach theWhitewire to the W terminal for the heat pump’sHeatingmode. 3). Attach theYellowwire to the Y terminal forAC/cooling mode. ...
A basic thermostat for heating and cooling uses four or five wires to control the HVAC system. The white (W), green (G) and yellow (Y) wires connect to the heating, air flow and cooling systems, respectively. The red cooling and heating (Rc and Rh...
Rh: Heating power. Rc: Cooling power. To reconnect the wire, simply put the wire on the right terminal and tighten down the set screw. Pull a wire a bit to make sure the wire is properly fixed. Example: Reconnect the red wire to R, tighten the screw, check, and move to the new ...
