What is B terminal on furnace?
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. Y1: The Y1 terminal is used for the compressor contact in a single-stage heat pump installation.
What color is the C wire on a furnace?
Blue wires
Blue wires are also called “C” wires because they are the Common wire. C wires are necessary for any “smart” thermostat that needs to be connected to a power source 24/7, regardless of your heat pump type.
How do you identify C wire?

The C and Rc wires are not the same. To install this thermostat you should follow the exact same wiring of the previous thermostat.
Does Goodman Use O or B?
A Goodman reversing valve is usually powered during cooling using the thermostat’s “O” terminal output. If the thermostat is set to “Cool” mode, you can check to see if it is putting out 24V on O.
How do I know if I have B or O wire?
Check the configuration. The heat pump is ‘O’ if it energizes in cooling and ‘B’ if it energizes on heating. Thermostats use the B terminal in systems with a reversing valve that turns on with heat mode. The system uses the O terminal if the reversing valve turns on while running cooling mode.
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.
What is C-wire on furnace?
WHAT IS A C-WIRE? A C-wire, or a common wire, runs from your low voltage heating system (24v) and carries continuous power to your thermostat. In today’s electric market, most newer heating and cooling systems have C-wires, which guarantees compatibility for the installation of all smart thermostats.
Where does blue wire go on furnace?
