Description
HOTWATER
In the standard hot water mode, the uint will start or stop based on
the difference between the temperature setpoint and the actual water
temperature. If the temperature setpoint is higher than that can be
achieved by the heat pump, only the electrical heater will be used for
heating when the heat pump is unavailable.)
