Thermostat R Or Rc at Alannah Herbert blog

Thermostat R Or Rc. If you have both an rh and an rc wire, the former powers the heating and the latter powers the cooling (using two separate transformers). All air conditioner thermostats have a red wire for power. R, rh, and rc are all the same, but not. In low voltage controlled systems, there will be a step down. They originate in the transformer (air conditioners; You typically have one or two of those three. Thermostat red wire (“r” or “rc” wire) red wire or “r” wire is the power wire. In general terms, the r terminal is where you connect the signal voltage source. Identify any wires labeled r, rh, or rc. Used for furnaces, heat pumps, modern air conditioners (mini splits, central air). If, for example, you have an r wire and an rc wire, the r wire controls the heating system. They are used with hvac systems with two. You may also have rc or rh terminals for dual transformer systems; “rc” and “rh” are terminals on an hvac thermostat, each with a specific function. If you have one wire — even if it’s labeled rc — it.
