Setting High And Low Balance Points
If your system is installed with the required Model 8041 Remote Outdoor Sensor, the high and low
balance points should have been properly set by your contractor.
Heat pumps operate by extracting energy out of the outdoor air and transferring it to the indoor air.
This process is efficient over a wide range of temperatures. However, at low outdoor temperatures
there is a point at which it becomes more economical to operate the backup heat without the heat
pump. Conversely, the use of backup heat with the heat pump during mild weather could use more
energy than is required to heat the home.
To review the set points, press and hold the OUTDOOR button and press FAN button. Hi bP and its
temperature value will appear on the display. Next, press the OUTDOOR button again and Lo bP and
its temperature value will appear on the display. After approximately 15 seconds the display will return
to normal.
After accessing a balance point, it can be changed by pressing the DECREASE button or
INCREASE button. This should only be done after consulting with a qualified contractor. Improperly
set balance points can result in increased energy expenses and possible equipment damage.
