In this instructional video, Ryan Hoger guides viewers through the process of wiring a heat pump system, highlighting the key differences between wiring a heat pump and a conventional air conditioning (AC) system. The focus is on a split system, which includes a heat pump combined with a natural gas furnace. The video covers the wiring of the thermostat, furnace, and heat pump.
Viewers will learn about the thermostat wiring terminals, which include C (common), R (hot), G (fan), Y (compressor), and a notable difference for heat pumps—W1 and W2, where W2 is used for the heat pump's auxiliary heat. Viewers will also learn the specifics of configuring the reversing valve.
For the furnace, there is a demonstration of the wiring process, showcasing wires coming from the thermostat into the furnace and then out to the heat pump. Moving on to the heat pump, the reversing valve is a major component differentiating a heat pump from an AC unit. The wiring process involves connecting wires such as O (reversing valve), R (24-volt power), W (heat), G (fan), and Y (compressor).
