In this troubleshooting situation, the equipment is an air source heat pump and the customer’s complaint is that even though the thermostat is set at 70° F, the temperature in the conditioned space remains near 65°.

Thermostats have gotten seriously smart in the last decade.

The primary objection: a wholesale price point that is four to five times the cost of a traditional thermostat.
