GE Heat Pump "Heat Boost" Function
I live on the 30th floor on the NW side of the building. There are 3 GE 3800 Zoneline heat pump systems used to heat/cool the house. The master bedroom seems to get the brunt of the winds and our NJ weather has been hovering at freezing or below for a month now. No matter how low I turn the thermostat, the master BR heat pump runs continuously kicking out pretty cool air, while the aux electric heats kicks on only sporadically. If I turn the thermostat up, though, the room gets too hot. The other two units don't seem to be having the same problem. I'm not sure if this is a function of the room location and the wind, or if this unit is having a problem.
Building maintenance was pretty useless with help, so I'm trying to trouble shoot this myself looking at the owner manual. There are two switches to the auxiliary controls I think might help...
1) The unit has a temp limiting function. Am I right to assume that if I limit the max temp to 70-72 degrees, that will help my issue with it getting to warm when I raise the thermostat?
2) It also has a "Heat Boost" option that according to the manual, locks out heat pump only operation when outdoor temps are between 25 and 40 degrees, which provides supplementary heat to the heat pump operation in conditions where the heat pump only operation is not sufficient to maintain a consistent room temp. This seems to be different than turning the heat pump off all together (there is a separate auxiliary control to do that), which I know is a bad idea from reading other posts. Having just suffered a $400 electric bill with the heat pumps operating without heat boost, I'm not sure whether this function will make the electric consumption better or worse?
I'd appreciate any advice you can give!
