Hi, I have an Amana 95IIQ furnace and a Filtrete CT50 thermostat. I connected W1 and W2 cables on both furnace and thermostat and I do not have any jumpers between them. The furnace is ignoring the thermostat's programming which should switch to stage 1 when temperature is within 2F of target. It instead runs initially on stage 1 and then switches to stage 2 after about 10 minutes until the target temp is met. This is making the house temperature very uncomfortable. I see a number of dip switches on the circuit board of the furnace but don't know what each does.
