Do I use RH or RC on Nest Thermostat?

The Nest Thermostat E only has an R connector, which is typically where an R wire would go. If you have separate heating and air conditioning systems, you might have separate Rh and Rc wires that come out of the wall and are connected to your system.

Why is there a jumper between RC and RH?



In most cases, the heating and cooling system share a single transformer by leaving the jumper in the lower right corner it connects the RC and RH to power heat and cool features.

Does red wire go to R or RC?

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 another wire (not a jumper) in the RC terminal, you will not need to connect the R and RC terminals. See our Basic Wiring article for more info here.

Is RC the same as C wire?

Is RC wire same as R?



RC is no different and simply means red cooling. The wire is generally red, although there is no color standardization — but more importantly, the “R” really means that the wire and terminal are hot; it’s a live electrical wire. The RC wire connects to the RC terminal, which controls the cooling system.

Can I jump R to C wire?

In the case of Nest and Honeywell (and probably others), their thermostats expect the C wire to come from the cooling system. When you’re connecting the wires to the thermostat in these systems, you’ll have to remove any jumpers between the R terminals.
