Selecting The Type Of External Sensor - Biasi RINNOVA ADAPTIVE User Manual And Installation Instructions

use electric cables with a cross section of no
less than 0.50 mm 2 .
The electrical conductors for connecting
the external sensor to the boiler must go
through different channels to those for the
mains voltage (230 V), as they are supplied
at a safe low voltage and cannot exceed 20
metres in length.
Use the terminals indicated in Figure 5.22 to
connect the external sensor.
The path of the external probe connection
wires must follow the path indicated in Figure
5.22.
Make the boiler cables exit using specific cable
glands R (Figure 5.24).
5.15 Selecting the type of external
sensor
The boiler is set to operate without an external
sensor.
If an external sensor (optional) IS CONNECT-
ED to the boiler, the correct parameter must
be set according to the type of probe installed.
