Trying to install 4 nest thermostats in my home , I currently have the original Trane thermostats and heat pumps and furnace blower unit, The wires are as follows both at the thermostat and at the furnace blower fan,
- (R is red,
- W2/X2 is black jumper to->W is white,
- Y is yellow,
- G is green,
- O is orange, is
- B is blue,( keep in mind B is not C, B is on B at the blower fan and C is empty,)
- Sometimes B is the C wire on the Trane brand unit but I'm sure the B is truly B which is a reversing valve and the O is another reversing valve im thinking but im not sure but there is a White W jump to W2 which is heat and a Yellow which is AC.
- I saw the C screw empty at the furnace panel where all the thermostat wires are pulled and terminated
- I have a Trane HVAC system Gas furnace with heat pumps , 4 Thermostats throughout the home Thank you in advance , I do have an extra black wire at each thermostat and at the furnace blower I can land at the C screw on the thermostats and at the fan blower as well. Please help and Thanks again in advance
