Thermostat Wiring Diagrams Furnaces. Heating Only Thermostat Wiring Diagrams If you only have a furnace such as a gas furnace, oil furnace, electric furnace, or a boiler. Therefore, you will use the following color code for simple thermostat wiring: Terminal R or terminal RH for the red wire. This originates from the transformer.
Wiring Diagram Using a Zone Valve with a 24 V Thermostat and a Transformer. For illustration purposes only: • Location of thermostat may vary. White Black R. 110 V Power Source 24 V Thermostat (p n 8200008) RC Y B O RH G W. Zone Valve. Unit Bypass Main – Back to Outdoor Furnace C W R C.
the power source is a low voltage transformer (usually a 24 VAC transformer) and the two wires supplying the power are labeled C (common) and R. The common or C wire need not be run out to the thermostat, however if the thermostat requires power, the C wire should be routed to the thermostat. Even if the

Furnace Thermostat Wiring Diagram Terminal Letters On a Thermostat and What They Control The Hot wire (24 volts) usually Red from the transformer is the main power wire to turn on or off a furnace components. For example, if the Red wire is connected to W on the thermostat the furnace should turn on. When the Red wire is disconnected from W the furnace should turn off.
If your home’s system of this vintage has provisions for air conditioning (cooling), then the thermostat wiring will have at least three wires (some will require a separate ‘R’ terminal for heating and cooling and will be labeled ‘Rh’ and ‘Rc’ now needing a minimum of 4 wires), ‘R’, ‘W’, and a ‘Y’ terminal.
Adding a 24 VAC external transformer: A DIY option for heat only systems without a common wire. If you have a heat only system connected to your Sensi thermostat, an easy option for adding a common, or c wire, is to install a 24 VAC wall plug in transformer.
The most common application for a 24 VAC transformer is to activate a doorbell chime. The lower voltage is sent to the push button to engage the chime mechanism. The 24 VAC transformer is also employed in many thermostats for home heating, ventilation and air conditioning systems.
