How To Wire A Thermostat Diagram These control the power, heat and fan. standard thermostats use 4 or 5 wires: r, w, g, y, and sometimes c. these control the power, heat, fan, and cooling. more advanced thermostats use 6 8 wires. the extra wires control additional hvac system features and settings, signaling a two stage cooling or heat pump system. Unscrew the two wires from the terminals. remove the motherboard of the old 2 wire thermostat and put the new 2 wire thermostat in its place. reconnect the red and white wire, tighten down the set screw, and put the control panel back on. test the 2 wire thermostat wiring by turning the furnace on.
Basic T Stat Wiring Diagram Here’s how to wire a thermostat using the color code and, fyi, each terminal’s purpose. attach the red wire to the r terminal (call for heating and or cooling). attach the green wire to the g terminal (fan). attach the white wire to the w terminal (heat). attach the yellow wire to the y terminal (ac). Yellow – the yellow wire connects to your compressor. green – the green wire connects to the fan. orange – this wire connects to your heat pump (if you have one). red – now, there can be two separate wires for this. one is for cool and the other is for heat, hence the abbreviation “rh” and “rc”. blue – this is your common or. Reconnect the wires to the correct terminals—white to “w” or “w1”, red to “r”, yellow or sky blue to y, and green to “g”—and tighten the screws until you’re sure they’re fixed in place. turn the heat pump or the hvac device on and check if it’s working properly. if it is, you’re done with the hvac thermostat wiring. Air conditioner thermostat wiring details and color code. r terminal is connected to the red wire or r wire this is 24 volt power for the thermostat and controlled devices. origin is the control transformer and then the r terminal. g terminal is connected to the green wire or g wire this is for the blower fan in the air handler.

If you have a c wire, place it into the c terminal on your wall plate. c wire adapters are available here. let’s look at the g wire. this wire goes to the g terminal on your new thermostat. of the y, y1, and y2 wires, y or y1 go to the y terminal and y2 to the y2 terminal. the o b wire can have many configurations. By the use of an adjustable set point, the job of the thermostat is to turn on either the heating or cooling system to maintain the desired room temperature in the home, and to turn off the system when the desired temperature is achieved. the most basic of systems (such as an older ‘heat only’ forced air gas furnace with a standing pilot.
