Hello, I am having troubles and wanted to ask here before i called a Pro. I tried to hook up the Wize thermostat but the C wire is giving me troubles. At the thermostat I have Y1 (Yellow), G (green), W1 (White) and RH (Red) (there is s blue wire but it was not hooked up wrapped around sheathing hanging). At the Unit I have Yellow, red, green, white (again a blue wire not hooked up wrapped around sheathing hanging). My problem is there is no way to get to the circuit board its hidden behind sheet metal, I have no way to connect the loose blue wire to C to use. Is there another place i can hook the blue too? Please see photos.
This is C
Strip the blue wire back a bit, and with the power off, add it to this wirenut.
At the thermostat, strip about 1/4 of an inch of insulation off of the blue wire and insert it into the C terminal on the thermostat backing plate
Make sure you tell it that your old thermostat has a C wire during setup.
