6.6 Setting up the power consumption control
You can use the following power consumption controls. For more information
about the corresponding settings, see "Power consumption control"[4204].
# Power consumption control
1 "Permanent power limitation"[459]
▪ Allows you to limit the power consumption of the entire heat pump
system (sum of outdoor unit and backup heater (if applicable)) with one
permanent setting.
▪ Limitation of power in kW or current in A.
2 "Power limitation activated by digital inputs"[460]
▪ Allows you to limit the power consumption of the entire heat pump
system (sum of outdoor unit and backup heater (if applicable)) via 4 digital
inputs.
▪ Limitation of power in kW or current in A.
3 "BBR16 power limitation"[462]
▪ 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 kW 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.
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 at least one electrical heater
(backup heater step1 or booster heater).
6.6.1 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.
