INFORMATION
Restriction: Current limitation by current sensors is only available for 3-phase setups
([9.3.2]=2 (Installer settings > Backup heater > Voltage = 400V, 3ph)).
NOTICE
Disconnected sensor. If you use current limitation by current sensors and one of the
sensors is disconnected, the corresponding phase is not limited anymore.
Current sensors can be used to limit the consumption of the heat pump on every
phase taking into account the set household fuse and the actual consumption of
other appliances.
Current sensors must be installed before the main fuses on each phase to make
use of this feature. This function can be useful in countries where the government
gives incentives to limit the fuse sizes.
