Temperature was below temperature that owner set and woke up cold. Temperatures could have dropped below desired temperature on thermostat if house is cooled down from outdoor temperatures. I checked voltage power at thermostat. I turned system on and off multiple times to assure blower motor didnâ€™t keep running. Blower motor shut off immediately when I would turn system off at thermostat. Not seeing any issues to system today. No charge for coming out on warranty call.
