Power consumption control
1
"5.6.1 Permanent power limitation"
▪
Allows you to limit the power consumption of the entire heat pump
system (sum of indoor unit and backup heater) with one permanent
setting.
▪
Limitation of power in kW or current in A.
2
"5.6.2 Power limitation activated by digital inputs"
▪
Allows you to limit the power consumption of the entire heat pump
system (sum of indoor unit and backup heater) via 4 digital inputs.
▪
Limitation of power in kW or current in A.
3
"5.6.4 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.
5.6.1 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.
