What Type Thermostat is Compatible| Heating and Cooling ...A two-stage or variable speed system may only be operating at a single speed because the thermostat or control system doesn’t allow for two-stage wiring. A dual fuel system, which is comprised of a gas furnace and a heat pump, should be connected to a thermostat or control system that can accommodate the specific heating set points.
How do I wire my thermostat? E – Emergency Heat. Aux / W2 – Heat Stage 2 (Heating) W – Heat Stage 1 (Heating) R – 24vac (Heating transformer) Rc – 24vac (Cooling transformer) *Trade model thermostats are required to operate "dual-fuel" systems (systems that use a heat pump for the first 1 or 2 stages of heating and use a gas or oil furnace for backup / emergency ...
Two"This furnace can operate as a two--stage furnace with a single-stage thermostat because the furnace control CPU includes a programmed adaptive sequence of controlled operation, which selects low-heat or high-heat operation. This selection is based upon the stored history of the length of previous gas-heating periods of the single--stage thermostat.
Single Stage vs Multi Stage Heating ... 2 Stage conventional cooling system – will have wires leading into terminal Y and Y1 (or Y1 and Y2) Two Stage Thermostat – 2 heat/ 2 cool option. Note: This image given above is of a thermostat which supports 2 stage systems (2H/2C – 2 stages of heating(W1, W2) & cooling (Y1, Y2) in a single thermostat). But this thermostat is actually wired as 1H/1C system as there is a jumper wire connecting W1 to W2 and another jumper wire connecting Y1 to Y2.
