NIVA 5 uses 5 level probes. The probes must be positioned in the buffer tank so that
the manual override level (S1) is below the buffer tank overflow.
Warning: To guarantee the reliability of detection, you are advised to install the
probes in a chute or a PVC pipe in order to isolate them from the wall and to
keep them separate. The probes must be fixed at the desired height to prevent
their movement and to avoid any pulling on the wire. The probe wires must be
guided to avoid their becoming tangled.
The probes are supplied with a length of cable which can prove insufficient to
connect them
regulation box. You are
then advised to prolong
the cables by using a
junction box.
connection between the
regulation box and the
junction box should not
exceed 50 m and will be
made with a 5-strand
flexible cable for
NIVA 5 (or 3 strand
flexible cable for
NIVA3) 1.5 mm ² (HO7RNF type for example). To ensure a good performance of
the installation, it is essential to ensure the sealing of the junction box and good
galvanic insulation of the contacts. The use of silicone adhesive is recommended.
To avoid wiring errors, the multi-strand wires must be
clearly marked, particularly if the 5 strands are not of
different colours. For the RO2V for example, care
should be taken to mark the position of the 2 black
wires.
