SOURCE: Need a wiring diagram for mastercool evap 2 stage unit
I have the wiring diagram in the cooler. I can photograph and send it to you. Do you still need it?

If you look at control box at roof unit, they usually use a separate set of wires for furnace. See what colors they are attached to at harness to thermostat. Some just follow other harness, and come out at thermostat. (bypass control box) Once you've determined which 2 they are, join them together & see if furnace starts, as it should. If it does, thermostat is faulty. If not, pull outside cover off & check voltages at furnace. I'm guessing by furnace model that your unit is approx 30 ft , but if it's a park model, you may have 24 volt system on furnace or 12 volt. Another way of confirming is to go to back of furnace where air intake grille is inside your unit, and locate 2 blue wires going to furnace & remove whatever wires are attached to them & connect them together. Furnace should start up.

It is technically possible use a 2-wire thermostat with a 3-wire zone valve, but you need a single pole, double throw relay like a fan control relay with one normally open switch and one normally closed switch. 2-wire thermostats only have one switch that is normally open. 3-wire thermostats have two switches......one switch that is normally open, and one switch that is normally closed. The fan relay lets the 2-wire thermostat simulate a 3-wire thermostat. It's possible, but usually it's easier to just get a 3-wire thermosts.
