"5.5.4 BBR16 power limitation"
▪
Restriction:
Only available in Swedish language.
▪
Allows you to comply with BBR16 regulations (Swedish energy
regulations).
▪
Limitation of power in kW.
▪
Can be combined with the other power consumption controls. If you do
so, the unit uses the most restrictive control.
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.
5.5.1 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.

Setup and configuration
▪
No additional equipment needed.
▪
Set the power consumption control settings in [9.9] via the user interface (see
175]):
-
Select continuous limitation mode
-
Select the type of limitation (power in kW or current in A)
-
Set the desired power limitation level
NOTICE
Set a minimum power consumption of ±3.6 kW to guarantee:
▪
Defrost operation. Otherwise, if defrosting is interrupted several times, the heat
exchanger will freeze up.
▪
Space heating and DHW production by allowing the backup heater step 1.
5.5.2 Power limitation activated by digital inputs
Power limitation is also useful in combination with an energy management system.
