what is a multistage thermostat exactly?  well, it’s for controlling multi stage hvac equipment, of course.  and by hvac equipment, i mean your furnace, air conditioner, or heat pump.  multi stage hvac equipment has multiple burners or compressors so it can heat or cool a home quickly but can use less of them when they’re not needed.  it’s like having an 8 cylinder suv that can drop down to 4 cylinders when they’re not needed (and those do exist, by the way, i’m pretty sure the new chevy tahoe can do it, which is better than putting a hybrid engine on a vehicle that size).  the therostat is able to turn those extra burners on and off.
