Alternate Heat Stage 2 Nest - ผม หนา เสน ใหญ ตด ทรง ไหน ดindexราน ลาบ ใกล ๆ ฉน 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).
