I have e 2 thermostats... 1) AS read on front.ATWOOD OPEN FLAME BURNER... 2) Coleman... I have a Coleman furnace... what is the purpose of the ATWOOD?? I live in a park model modular... thanks.

The atwood was for a Atwood furnace if the park model was going to use 12 volts. You are probably hooked up to 220 or 115 volts so unless the Atwood thermostat is wired to a furnace do not worry about it.
