Trane Thermostat B Wire
What is B on the Trane thermostat?
B Heat pump change (from cold to hot, used in heating mode) For thermostat applications that use a blue wire, blue is usually a normal circuit wire, eg. which provides the return path for the circuit. B and O together. Trane products for heat pumps.
What is B on a thermostat?
A line with O, B or O / B is used to check if a heat pump is in heating or cooling mode. On some thermostats, a wire labeled B is the common wire C. In most cases, the common wire is labeled C.

And what is the B terminal of the oven?W / B: The W / B connection controls the relay or the heating valve. When the thermostat calls for heat, it sends a signal to turn on the stove and the fan or water heater and turn on the heating in the house.
How is a Trane thermostat connected?
Instructions for connecting a Tranter thermostat
- Choose your thermostat according to your needs.
- Connect the thermostat wires.
- Connect the wires exactly as you connected them in the previous step, except that there is an orange wire that goes to the switch valve.
- Turn on the switch and test the device.
Is the RC cable the same as the C cable?
Although widely believed, it may be wrong to say that Cwire controls the thermostat. Generally, the wires that provide power (usually called hot wires) are called Rc (for cooling) and Rh (for heating). They supply 24 volts of electricity via the HVAC system control panel.
How does a 2-stage thermostat work?
Two-stage heating means the stove has two levels of heating: high for cold winter days and low for milder days. Since the low setting is enough to meet household needs 80% of the time, a two-stage device will run longer and provide more even heat distribution.
What do the letters on a thermostat mean?
What do the letters on the thermostat clips mean? The terminals have letters that refer to the functions. R is the power of the transformer, generally 24 V AC. Rc stands for the cooling capacity of the separate transformer. W is hot, C is normal.
How many wires does a thermostat need?
In the simplest system this functionality is provided by a central fan relay, and the low voltage line to the thermostat now requires at least three wires (for heaters only) and four wires (for heating / cooling / fans) for control.
How do I reset the thermostat?
Here are the steps to reset the AC thermostat. Turn off the thermostat. The first step in resetting the AC thermostat is to turn it off on the AC device. Find your control box. Reset the AC breaker. Wait 30 seconds. Turn the AC thermostat back on.
What does C mean on the thermostat?
What is wire C on a thermostat? Wire C is an additional wire that can be used to provide a 24 VDC return path for all applications. It is typically used to provide a return line for thermostat operation. C stands for together.
What color is the C lead of a thermostat?
Common uses of wire colors are: Blue or Black - C - Normal wire, cannot be used by existing thermostat. Allows continuous feeding of the red cable. Red - R - 24VAC power supply from the furnace transformer.
R and Rh the same on a thermostat?
R, Rh and Rc are the same, but not. Usually the R terminal is where the voltage source of the signal connects. This allows current to flow from the R terminal and the current signal terminal (W, Y, etc.) on the thermostat.
How many wires can be connected to terminal C of the oven?
Technically, only one wire should be connected to the screw terminal. However, it is common in the plumbing industry to connect more. If you want to get it right, you'll need to use a twiston wire plug (or whatever plug you choose) and a piece of scrap wire to make a pigtail.
What does Y mean on the thermostat?
Y = cold load. When cooling is required, the thermostat closes a switch between R and Y and sends 24 V to activate the cooling circuit. G = fan load. When cooling is required, the thermostat closes the switches between R and Y and R and G, which provide both cooling and fans.
