And variable speed blowers can be tricky because they are so quiet. It should look like this: There are two sides to the transformer, the line side with high voltage one one side of the transformer and the control side which are the wires that provide the control voltage for the system. Posted on Dec 20, 2007 What is the model number? The fix could be something very simple or it could something very complex. Assuming the black and white wires are properly traced, is it likely the white wire goes to W for heating, and the black wire goes to Aux or W-2? In other words, does the air handler control electronics activate the fan itself, or does the tstat always run the fan motor in every mode? Many systems only have a single compressor but if you have two compressors or a two stage compressor which should only operate off of one then you need the Y2 thermostat terminal for second stage cooling. For the thermostat wiring colors code for this terminal if equipped consult with the installer or trace the wire out to the source.
This is why I recommend to people, when they select the communicating thermostats when they buy a new system, to make sure the contractor leaves the conventional wiring in the wall.
