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.
