What do I do with the e wire on a Nest thermostat?

Some thermostats have an E connector. The E wire turns your emergency heat on or off. Emergency heat is usually used when it’s too cold outside for your regular heater to keep your home warm.

What is the difference between RC and RH on a Nest thermostat?

Where does RC wire go on Nest?

Note: If you have an R, Rc or Rh wire, you can put it into the R connector on the Nest Thermostat. If you have a W2, Y2 or O/B wire, you can put it into the *O/B connector, if needed. Gently tug each wire to check they’re secure, and make sure each connector that has a wire stays down.

Should RC and RH be connected?

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.

Why does my thermostat have a jumper from RC to RH?
