Connecting the outside sensor
Install the outside temperature sensor in the shade on a
wall facing north or north-west, so it is unaffected by the
morning sun. The sensor is connected to terminals X1:1
and X1:2 on the load monitor card (2). Use a two-core ca-
ble of at least 0.5 mm.

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.
