“Auxillary Heat at 69”
It will be a two-stage System. Thermostat will go into Heat1 at a few degrees below the goal. Heat2 is when you are like 5 degrees below. All it means is a stage two wired device kicks in. Your hvac may not even have that device. Usually Heat1 is heat pump, Heat2 is the electric heat coils. Heat1 draws maybe 3 or 4 kilowatts, Heat2 as much as 8 kw.
Just because thermostat display says something, does not mean the hardware exists. If system is older, thermostat may have been replaced since installation.
Emerg really means both stages are in play and nothing more.
Our Aux heat is gas so really warm. We put last night’s leftovers in the garage. 8 degrees and my daughter’s BF just took the dogs out for a walk. Lucky him.
The warmest hat I have is a Santa hat so I will be wearing that to the Walmarts. I need kitty litter, a box of wine, a bottle of stool softeners and some Scratchers. Won’t the kids be surprised when they look under the tree tomorrow?
No its only a few years old I got it replaced when the original died one winter ...
