Heat Pump T Stat Wiring 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.
Ac Thermostat Wiring Diagram Explained For Hvac 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). G – green: fan – this is for the blower in the air handler. r – red: 24 volt power – your air handler is powered by 110v, but it is converted to 24v for the thermostat. c – blue: common wire for continuous 24 volt power from the thermostat to the air handler. e – white (optional): emergency heat. 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. Mostly for new digital thermostats that require continuous power via c wire. typical 6 wire thermostats will use red (r or rc or rh), white (w, w1), yellow (y, y1), green (g), black or blue c wire, and orange (o b) wire for reversing valve switch; used for complex heat pumps. thermostat wire color meanings are standardized.

Overview of different heat pump terminals. as shown in the diagram, you will need to power up the thermostat, and the 24v ac power is connected to the r and c terminals. the color of wire r is usually red wire, and c is black wire. the c wire is known as the common wire. these two connections will ensure that there is power to the thermostat. The hvac wiring diagram thermostat illustrates the electrical connections between the thermostat, the heating or cooling system, and the power supply. it shows the different wires and terminals involved in the system and their corresponding functions. the diagram provides a visual representation of how the thermostat interacts with the hvac.
