Is any of you have experience installing mars comfort air centralized ac? How can I wired outdoor unit using regular 24 volt thermostat? Attached is the wiring diagram of the unit?

Trying to wire this to furnace with 24 volts thermostat

Flip dip switches 2 & 3 ON.

Wire C & Y2.

Wondering why this option isn't on the installation manual, wondering where you get it. will try it, thanks admin

They released that addendum after the fact.

I also attached the CMA15 line set sizing chart.  Most people assume you have to use 3/4" copper but you can save a fortune using smaller sizes.

Perfect, thanks again
