Furnace Thermostat Wiring And Troubleshooting Diagram вђ Hvac How To R or rc wire (power) connected to the r power terminal to power the thermostat. w wire (heat), connected to the heating control. g wire (fan) connected to the fan control to operate a blower in your hvac system. y1 wire (cooling) connected to the y terminal compressor refrigerant system. In this hvac installation training video, i show how to wire the low voltage thermostat wires into a furnace and ac unit. i explain what each of the letter t.
Wiring A Thermostat To A Furnace Basic thermostat wiring for furnace and air conditioner. i show where the wires go at the thermostat, the color code, then down at the furnace control board,. Y – yellow: cooling mode. this wire runs to the furnace control board which in turn controls the activation of the compressor and related components required for ac. g – green: this wire controls the blower motor in the furnace. y2 – light blue: this wire is necessary if you have a two stage ac compressor. Thermostats use 24 volts ac from a transformer to control a furnace. the transformer steps down 120 volts to the 24 volts the thermostat needs, and sends out the 24 volts on two wires. the two 24 volt wires go to the r terminal and c terminal inside the thermostat. r is the hot side, while c is the common side of the transformer. The thermostat wiring diagram for a furnace typically shows the different wires and terminals that are used to connect the thermostat to the furnace. these wires include the r (red) wire, which is the power wire that provides 24 volt power to the thermostat; the c (blue) wire, which is the common wire that completes the circuit; the w (white.

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). 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.
