mode AUTO. DHP-AQ Midi and DHP-AQ Maxi has three outputs, IMM. HEAT 1, IMM. HEAT 2 and IMM. HEAT 3 and output can be control-

led in five steps.

sion heater step: +4 and +5 can be connected 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 electric 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.

In DHP-AQ Midi and DHP-AQ Maxi a multi power stage heater (IMM HEATER) is factory installed. The heat pump control system engage

the appropriate amount of heating power to ensure the desired heating system temperature. Below is a table describing the different
