Wiring Nest to Mitsubishi PAC-US444CN-1 with radiant heating as primary heat source
Has anybody had success connecting a Nest (3rd Generation) to a Mitsubishi PAC-US444CN-1 where the primary heating source is radiant? Currently, my Nest is used to control my radiant heating and receives power from the current setup (wires: W1, C, RH). I would like to connect my Mitsubishi SEZ-KD12NA4 to the Nest. Because the Nest is already being powered by the radiant unit, I don't think I need to connect a transformer (is this correct?). Using the wiring example provided in the manual for single stage cooling with alternate primary heating source, I think I only need to connect wires Y1, G and W1 from the PAC-US444CN-1 to the Nest inputs Y1, G andW2. Is this correct? Does anybody have any other thoughts or wiring examples that have worked for them? Thanks in advance for the assistance.
