Alternate Heat Stage 2 Nest - My observation has been that it looks at the distance from target. My nest thermostat is configured as stage 1: Alternative heat use is set at the lowest possible temperature, 10 degrees f. My nest says stage 2 heat but isn’t heating!!! I'm sorry to hear that your nest thermostat is not heating even though it says stage 2 heat, but our hvac. You'll need to set all your heat sources to electric and get the nest out of dual fuel mode. This should make it so that the wire in w2/aux is being treated as auxiliary heat (not alternate heat). What exactly is a heat stage 2 nest? When the furnace is turned on, “heat stage2” is always. Takes like 2 minutes to heat up using gas. My google nest usually heats the house fine, but i’ve noticed on cold days it doesn’t keep up. It’s set to 72 degrees right now, but the thermostat says “heat stage 2” and does not seem.
