I have just had a new Amana System Installed...and since it has been@ 100-108 Degrees lately..the Heating side of things has NOT COME UP!.
My Furnace is an Amana 2 Stage GHD80-70 Gas downflow furnace..
The cooling is strictly single stage..and that suits me fine..
The 2 Stage heat seems to be controlled by the furnace itself and is selectable through a DIP switch in the furnace rather than a W1/W2 wiring to the tstat to regulate staging.
When the system was initially installed..I noticed that they left it in single stage heating.
At my request.... (And after reviewing their SALES PITCH back to them) they changed it to 2 stage heating.
My question is...why is the furnace deciding to operate in first or second stage?
Shouldn't that decision come from the tstat??
Thanks for the Info..you guys are the best!!!!
