“Smart Grid” function via the Heat Pump Manager
Operating state 1 – heat pump is disabled
The heat pump consumes no power and only the room heating pumps
run as required.
Operating state 2 – heat pump running normally
The heat pump operates normally as a heat pump without integration
in an intelligent power grid.
Operating state 3 – heat pump switch-on recommendation
The heat pump works in an increased mode and provides more heat
or cooling than in the normal mode. The amount of the increased
requirement can be set for the individual consumers via a percentage
increase of the target values. In concrete terms, the target temperatures
are increased or modified so that (for example) the target temperature
of the hot-water tank in operating mode 3 is increased by a minimum of
5 % and a maximum of 20 % (SW Incr. = 5 % and 20 %).
The actual increase or reduction can be set by the user within the
specified limits. Values outside the min./max. limits are not possible.
The settings for operating state 3 are listed in the following table.
