Question about Honeywell Programmable Thermostat Heater
Our old Maple Chase thermostat was replaced with a FocusPRO TH6220D. During regular operation the furnace does not come on and the system is running off only the heat pump. It turns on 1-2 hours before the wake time trying to warm the house off only the heat pump when the temperature outside is 35-40 degrees. We were away this past weekend, and my neighbor called to say the heat pump had been running continuously and there was a thick frost (1-2 inches) over the entire heat pump unit inside and out. Is there a way to make the thermostat use the furnace and the heat pump together. It does not seem to be very efficient the way it is working right now. I have turned it to EM heat so that it will not run only the heat pump, so I am running only the furnace. Also, we do not like the cycles per hour setting, is it okay to change it to a lower frequency? I believe it is set to 9 as per the installation manual. Thank you, Jeanette Heylen Bainbridge Island, WA
Someone did not program your thermostat to operate according to your heat and air requirements.
Have it programmed correctly.
