Atwood 8900 Furnace
Atwood Heat Only Thermostat
I replaced my roof air unit with an Atwood. The new unit has its own thermostat so I removed my original (Duotherm) and installed the provided Atwood T-stat to control the AC. It works fine both for cold and heat from that unit.
The Duotherm also controlled the furnace so I needed to install a direct heat only Atwood t-stat to control my single furnace. I am doing something wrong and am looking for some help. The furnace runs, provides heat and shuts down with the switch but will not shut down automatically when it reaches the target temp. Even on the lowest setting it continues to run. The t-stat is new.
I read Gary Brinck's great furnace document and it indicates my problem has something to do with the Time Delay Relay. I am definitely confused at this point.
Where am I supposed to connect the two wires from the t-stat (red & white) at the furnace?
Thanks.
