Load monitor

NOTE
The load monitor has no function in a 1-phase
installation.
When many power consumers are connected in the
property at the same time as the electric addition is
operating, there is a risk of the property's main fuse
tripping. The heat pump has integrated load monitors
that control the electrical steps for the electrical addi-
tion by redistributing the power between the different
phases or disengaging in event of overload in a phase.
Reconnection occurs when other current consumption
is reduced.
Connecting current sensors
A current sensor should be installed on each incoming
phase conductor in to the distribution box to measure
the current. The distribution box is an appropriate in-
stallation point.
Connect the current sensors to a multi-core cable in an
enclosure next to the distribution box. Use a multi-core
cable of at least 0.5 mm2 from the enclosure to the
heat pump.
Connect the cable to the input card (AA3) on terminal
block X4:1-4 where X4:1 is the common terminal block
for the three current sensors.
The size of the property's main fuse is set in menu
5.1.12.
