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
225].
# Power consumption control
1 "6.6.1 Permanent power limitation" [ 4 59]
▪ 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 "6.6.2 Power limitation activated by digital inputs" [
4
59]
▪ 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 "6.6.4 BBR16 power limitation" [
4
61]
▪ 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.
4 "6.6.5 Smart Grid capacity limitation due to buffering" [
4
62]
▪ Restriction: Only available if a Smart Grid is installed and Recommended
on mode is active.
▪ Allows you to limit the power consumption of the entire heat pump
system (sum of outdoor unit and backup heater or booster heater (if
electrical heaters are allowed for buffering)) with a pulse meter or by
using setting [9.8.8]
Limit setting kW .
▪ Limitation of power in kW.
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.
