I am in Massachusetts and have a heat pump system in my condo. I realize this is a bad setup for this area, but changing it out is not really an option. I had the heat pump replaced with a Trane unit in 2005, but the original air handler (with auxiliary heat strips or coils) remains. My question though, is about the thermostat. I currently have a Robertshaw non-programmable unit. It is set to call for heat when the temp variation is 1 degree. Every time though, it calls for the auxiliary heat strips/coils to come on with the heat pump. I have heard that there are newer thermostats that have new adaptive technology that will not call for the expensive backup strips with the heat pump every time. I would like to know which is the best for getting the heat pump to do the work as much as possible. Thanks in advance for all replies.
