You can use the following power consumption controls. For more information
about the corresponding settings, see
#
1
"Permanent power
▪
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
"Power limitation activated by digital
▪
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
"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 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 the backup heater step 1.
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.
