5.1 Communication between the thermal
modules
Communication between all the modules installed is a funda-
mental aspect in a system with multiple thermal modules.
The essential steps for configuration are:
− allow the Managing module to recognise which and how
many depending modules are present in the system. Act
on the dip-switch
− connect the thermal modules with a BUS cable to allow
communication between the control units.
5.1.1

Setting the dip-switch

The dip-switches of all the thermal modules in the system must
be set, and each must be set with an unequivocal sequence.
This way the controller of the Managing module will be able to
recognise which thermal modules are present in the system.
To access the dip-switches, open the hatch using a flat-bladed
screwdriver.

The setting must be carried out on each thermal module.
For configuration of the individual thermal module, refer to
the following table.

If two modules have the same Dip-switch setting, the Man-
aging module will signal a communication error and the
cascade will not work correctly.

A module will not be considered if it has the setting of all the
Dip-switches set to OFF .
