Hmmm....as I’m reading my new Thermostat manual I’m wondering...
Our HVAC guy installed a White-Rodgers 1F80-224 Thermostat with our Amana Prestige 14 SEER and AMV8 Furnace.
Now, I’m no expert - in fact I know nothing - but is seems this is a Single Stage Themo and the AMV8 is a 2 Stage/Var Furnace.
Spec sheet on the AMV8 states:
A 2-stage thermostat should be used with the AMV8 furnace. A 2-stage thermostat controls which firing rate is used depending on the temperature difference between the set point and the room temperature. A properly used 2-stage thermostat and furnace will maintain a much tighter control of
temperature than a conventional single-stage thermostat and furnace. A 2-stage furnace has both “W1” and “W2” terminals. If the thermostat has “Y1” and “Y2” cooling connections and a single-stage cooling system is used, connect “Y” on the furnace control to “Y1” on the thermostat. The table below
describes 2-stage thermostats which have been set up for use with this furnace.
Model Two-Stage Thermostat Description Color
1213411 Digital, Non-Programmable, 2-stage, 2 Heat/2 Cool White
1213407 Digital, Programmable, 2-stage, 2 Heat/1 Gool White
1213406* Programmable, 3-stage, Manual or Automatic Changeover Beige
Also, the cover sheet of the Manual of the 1F80-224 Thermostat states:
DO NOT USE WITH (their caps, not mine):
Do I have a mismatch here?? If so what model (W-R) Thermo should I replace with?
