Connecting the outside sensor
Install the outdoor temperature sensor in the shade on a
wall facing north or north-west, so it is unaffected by the
morning sun. Connect the sensor to terminal block X1:1
and X1:2 on the load monitor board (AA22) via cable
grommet UB4. Use a 2-core cable of at least 0.5 mm
2 .
If the outside sensor cable runs close to power cables,
shielded cable must be used.
If a conduit is used it must be sealed to prevent condensa-
tion in the sensor capsule.
Connecting the current limiter
NOTE
Only applies to 3X400V.
When many power consumers are connected in the
property at the same time as the electric addition is oper-
ating, there is a risk of the property's main fuse tripping.
ACVM 270 is equipped with an integrated current limiter
that controls the electrical steps and the compressor. If
necessary, the electrical steps are disengaged and/or the
compressor frequency is reduced.
