Hi, everyone. I have a question about my thermostat.
Last summer I purchased a brand new electric AC/heating system. It is a 13 seer, 3.5 ton, Rheem. The installer also put in a brand new Honeywell FocusPro TH5000 series thermostat.
Since the colder weather has arrived, I have noticed that the furnace is running 3 minutes on, 5 minutes off.
I did some researching and from what I can tell it could be that the thermostat's heat cycle rate might need an adjustment.
The factory default is 9 cycles per hour, but it also offers alternative cycles of 2,4,6,7,8,10,11, or 12. It shows setting 1 is for a gravity system, 3 is for a hot water system, and 5 is for gas or oil furnaces with less than 90% efficiency.
It does not allow you adjust the temperature variation (like up/down 1 degree) - only the cycles per hour.
I have seen several similiar posts where people recommend switching it to 3 cycles per hour.
So my questions are:
1. Do you think changing the cycles per hour to 3 is right, okay, better for the system?
2. Do I need to adjust any other settings? The emergency heat cycle also defaults to 9. Should this one be adjusted to 3 as well?
I can call the installer (the unit is under warranty), but if it is just an adjustment I can make to the thermostat, I won't have to waste his time.
I appreciate your professional opinions!
