Does your heat pump use an O wire or B wire nest?
If you have a heat pump and your thermostat doesn’t have a separate wire labeled O, then the wire labeled B should be connected to the Nest thermostat’s O/B connector.
Is R and Rh the same on a thermostat?
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.
What is the difference between RH and RC on Nest thermostat?
This wire is also known as the RH wire. Rh stands for Red-Heat and Rc stands for Red-Cool. If you only have a single red wire the jumper between Rh and Rc are required for some heating and cooling hybrid systems depending on your thermostat.
What thermostats are compatible with heat pump?

Does my heat pump use O or B?
O stands for orange and B for dark blue.
The O and B terminals are for heat pumps; the B terminal is used in conjunction with Rheem, Ruud, or any other manufacturer that energizes the reversing valve in the heat pump’s heating mode.
What color is the OB wire?
Orange
Thermostat Wiring Color Code Chart
| Marking | Wire Color Code | Description |
|---|---|---|
| O | Orange | Change-over relay to cool relay |
| B | Blue | Change-over relay to heat relay |
| A | Heat and cool active to any relay | |
| L | Emergency heat active lamp |
Should thermostat be on O or B?
Most commonly, O/B is energized in Cooling (O on cool). For Rheem or Ruud brand heat pumps, the O/B must energize on heating (B on Heat).
Does R go to RC or RH nest?
Here are some general guidelines: An R wire can go into a Nest Learning Thermostat’s Rc or Rh connector. The Nest Thermostat E only has an R connector, which is typically where an R wire would go.These are not jumper wires, and you can insert the Rc wire into the Rc connector and the Rh wire into the Rh connector.
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.
What is OB on Nest thermostat?
A Nest thermostat’s star connector or. O/B connector can be used to control several different system functions, depending on what type of system you have. For example, you can use the star connector to connect a wire that controls a humidifier or dehumidifier, or emergency heat.
Do I use RC or RH?
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.
What is the O B wire?
O, B, O/B: These wires are responsible for switching the changeover valve in a heat pump system. The O wire reverses the valve from heating to cooling, and the B wire switches the valve from cooling to heating. Sometimes it might be a single O/B wire instead of two separate wires.
