How to Identify Each Wire for an HVAC for a Thermostat ... Most thermostats send commands to your HVAC system – heat or air conditioning – via low voltage wires inside a command box. This box enables you to set the temperature and configure heat or air conditioning programs depending on your habits and needs. Occasionally, either the thermostat box or HVAC unit itself may require some maintenance. Wire A Thermostat how to wire it The basic Heat A C System thermostat typically utilizes only 5 terminals. RC Red Wire (Power 24 Vac) RH or 4 Red Wire Jumpered (Power 24 Vac) W White Wire (For Heating Enable) Y Yellow Wire (For Cooling Enable) G Green Wire (Controls Fan ON Auto) The diagram shows how the wiring works.

Room thermostat wiring diagrams for HVAC systems At left the thermostat wiring diagram illustrates typical use of a Flair APOV2 wall thermostat in a 3 wire application controlling a heating appliance. In this application the thermostat is acting as a single pole double throw (spdt) switch to control heating & cooling or in some zone valve applications. Thermostat signals and wiring xtronics For electric heating, the thermostat controls the fan (G), thus in this case both G (Fan) and W (heat) are connected to R (24 VAC). For heating applications, a lower blower speed is used and the furnace selects it. The furnace controls the fan because oil and gas heat is not instantaneous.
