When the operation is set to HOT WATER mode, the reversing valve
hot water is set towards the heating system. To minimize the risk that
the outdoor unit freezes at low outdoor temperatures (that is, below
5°C) the reversing valve hot water is set towards the water heater and
the circulation pump starts to ensure a sufficient flow. When the out-
door temperature is above 5°C, the circulation pump stops and the re-
versing valve hot water is set towards the house (the heating system)
again.

Activate the electrical auxiliary heater in iTec Total
If the heat demand is greater than the heat pump’s compressor capacity, the immersion heater engages automatically in operating
mode AUTO. iTec Total has three outputs, IMM. HEAT 1, IMM. HEAT 2 (factory default) and IMM. HEAT 3 and output can be controlled in
five steps.
The two power steps, step 4 and step 5 for iTec Total cannot be activated when the compressor is running. Immersion heater step: +4
and +5 can be selected when the compressor is running and must only be selected on the condition that the building where the heat
pump is installed has a large heating demand and the building’s electrical installation is suitable for high current consumption. In the
event of an alarm, the immersion heater engages automatically on the condition that operating mode AUTO is selected and that at least
one additional step is permitted.
