Steps Unit
There are two operation modes:
Standard: DHW heating operation starts when the
temperature of the water in the tank is low enough
to start up the heat pump. DHW is always heated
- - up with the heat pump.
High Demand: DHW heating operation starts if the
differential is larger than differential temperature.
DHW can be heated up using the heater, the heat
pump or a combination of both.
There are two tank heat up controls:
High Efficiency: Compressor operation is adjusted
to optimal efficiency for lower power consumption.
- -
High Speed: The heat pump is switched to
maximum operation capacity to heat up the tank in
the shortest time.
Setting for domestic hot water temperature selected
by the user. The maximum value of this setting
