min
The minimum heat source temperature allowed dur-
ing the operation of the heat pump can be regulated
here. If inlet heat source temperature T1 is below
D7 Source T min, the heat pump stops and the elec-
tric heater runs until the water set point is reached.

The maximum heat source temperature allowed
during the operation of the heat pump can be
regulated here. If inlet heat source temperature T1
is above D8 Source T max, the heat pump stops and
the electric heater runs until the water set point is
reached.

The maximum heat source outlet temperature T2
allowed during the operation of the heat pump can
be set. If T2 is higher than the set point, then the
heat pump stops and elecric heater is activated.

The legionella function can be activated. The
legionella function does not switch the heat pump
on, but just continues the heat up cycle to a higher
temperature D14 (Legionella T). The legionella
operation works only with the heat pump until
D28 (T HP MAX). The remaining temperature lift is
accomplished with the electric heater alone.
