Connecting temperature sensors:
The cable connecting the mixed temperature outlet and return temperature sen-
sors must be installed in a dedicated raceway. If the connection cable shares
the raceway with other live cables, an earthed shielded cable must be used.
In case of reverse polarity or power failure the system enters the BATTERY
ALARM STATUS, see “Alarms” section.
