Thermostat Wiring Diagram for Advent AC Unit part # ACM135B

Question

Question:

The 12vdc for the thermostat is supplied by the main unit. So there is no need to run a12vdc line to the main unit. Correct? In other words, the only power wires I need to run for an entire new install is the 120VAC line? Please confirm this as I’m getting ready to put the roof on this RV rebuild and I have to run all necessary wiring now before closing the roof. Thanks

This is correct. The 12 volt DC input for the thermostat comes from the main AC unit and does not need to be ran separately.
