Furnace Thermostat Wiring And Troubleshooting Diagram вђ Hvac Ho 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. 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. if the ac is single stage, this terminal will be empty. w2 – light brown: this wire functions like the light blue wire but for furnaces with low and high stages of heating.
Electric Furnace Thermostat Wiring Diagram 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,. 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. 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. furnace 24 volt transformer. r is the hot side, while c is the common side of. 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.
Typical Thermostat Wiring Diagram 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. furnace 24 volt transformer. r is the hot side, while c is the common side of. 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. 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).
