What is the difference between RH and RC on Nest Thermostat?
The RH wire refers to red heating which means that this is the connection you need in order to power the heating system of your air conditioning unit.The RC wire, on the other hand, refers to red cooling. It’s the same with the RH wire in that it powers the thermostat. For the RC, it powers the cooling system.
Does Nest need power supply?
The Nest Thermostat must be plugged into mains power or wired into a heating system’s power supply to function. Without a constant power supply, it won’t be able to control a home’s HVAC systems.
Is RH same as R?
Understanding what RC stands for means, you can probably take an educated guess as to the meaning of RH. The “R” still indicates it’s a hot wire and terminal connection, and the “H” simply means heating. The RH wire connects to the RH terminal and controls the heating part of the thermostat.
Does the red wire go to RC or RH?
If you have both an Rh (Red-heat for powering the heating) and an Rc (Red-cool for powering the cooling), then the R wire can be connected to either Rh or Rc.If you only have a single R wire, then it will only have an R connector, which is the connection you’ll use.
Do I need a jumper from R to RC?
If you have a wire in the R terminal, and no wire in the RC terminal, use the jumper selector switch, the jumper plug, or a small jumper wire to connect the R and Rc terminals.If you have a wire in the R terminal, and another wire (not a jumper) in the RC terminal, you will not need to connect the R and RC terminals.
