What is the B terminal on a Trane thermostat?
W/B: The W/B terminal controls the heat relay or valve. When the thermostat calls for heat, a signal is sent to power up the furnace and the blower fan or the boiler, heating your home.
How do you wire a Trane thermostat?
The yellow wire is connected to the coil on the cooling contactor, and the other end is connected to the Y terminal on the thermostat. The white wire is connected to the relay for the electric heat, or the gas valve. The green wire is connected to the fan relay and connected to the G terminal on the Trane thermostat.
What is the B wire on a Honeywell thermostat?
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.
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.
Is B and C wire the same?
The common wire, usually labeled C, should go in the C Terminal of the Zen Thermostat. A wire labeled O, B, or O/B is used to control whether a heat pump is in heating or cooling mode. However, on some thermostats, a wire labeled B is the common wire C. In most cases, the common wire is labeled C.
Does Trane thermostat have C wire?
The blue wire is the C wire. Using a multimeter set to AC volts, you should measure about 24 volts between the red and blue wires. Connect a wire between the blue wire terminal on the transformer, and the C terminal on the thermostat. That should get you up and running.

How do you know if a reversing valve is 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.
Can I connect RC and RH together?
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. These are not jumper wires, and you can insert the Rc wire into the Rc connector and the Rh wire into the Rh connector.
