I am trying to install a new wifi thermostat in my home and need to locate the common terminal for my air handler. I have a Carrier model FB4CNF030. It's a new construction home and I have the blue common run but it is not connected at the air handler side
I've referred to the post at How can I add a "C" wire to my thermostat? and understand the purpose of the common but still don't know where to hook it up. I can't find the wiring schematic for this unit.
Any suggestions are greatly appreciated.
