5.6 Setting up the power consumption control
▪
The power consumption control:
-
Allows you to limit the power consumption of the entire system (sum of
outdoor unit, indoor unit and backup heater).
-
Configuration: Set the power limitation level and how it has to be achieved via
the user interface.
▪
The power limitation level can be expressed as:
-
Maximum running current (in A)
-
Maximum power input (in kW)
▪
The power limitation level can be activated:
-
Permanently
-
By digital inputs
NOTICE
It is possible to install a field fuse with lower than recommended rating over the heat
pump. For this you must modify field setting [2‑0E] according to the maximum
allowed current over the heat pump.
Note that field setting [2‑0E] overrules all power consumption control settings.
Power limiting the heat pump will reduce performance.
5.6.1 Permanent power limitation
Permanent power limitation is useful to assure a maximum power or current input
of the system. In some countries, legislation limits the maximum power
consumption for space heating and DHW production.
