I am trying to wire a Honeywell 7500 series thermostat to a Goodman gph1560m41a. The schematics on the manuals do not match. I get heat when I turn on the cold and no cold or anything when I turn on the heat. This is a 24-volt system (on low voltage), 2-stage hot/cold with optional 3rd stage heating. I need to know the wiring schematics.

EXACT and complete model number off the honeywell thermostat?

Exact and complete brand and model number off the old thermostat?

Some wiring for you in the mean time
