Thermostat Operation
The BOREAL® heat pump comes supplied with a
2-stage heating / 1-stage cooling auto change-over
digital thermostat.
The heat pump is already prewired for this stat and
requires only the connections mentioned above for
full operation.
The thermostat operates the heat pump as the first
stage of heat bringing the electric backup on only if
required. There is a 2° differential between the first
and second stage of heat. The thermostat automati-
cally changes between heating and cooling as re-
quired by the building.
