CASCADE CONNECTION
4.1.2
Setting the dip-switch
9
Perform this operation only on the cascade-connected
thermal modules such as "DEPENDING".
The dip-swich of all the thermal elements in the system must be
set and each must be set with a unique sequence.
In this way, the central unit of the managing module will be
able to recognize how many thermal elements are present in
the system.
To access the dip-switches, open the hatch using a flat-bladed
screwdriver.
9
The dip-switches must be configured in sequence. The
thermal module 1 will always be correct because the config-
uration has not been changed. From the thermal module 2
onwards, after modifying the configuration (from "MANAG-
ING" to "DEPENDING"), it is necessary to keep the elements
in a sequence.

Bus connection
The bus connections are made on the MANAGING "M01" low voltage terminal blocks of the connected thermal modules in cascade.
Locate the thermal module that will be deputed to be MANAGING of the system.
Connect a bipolar cable to the contacts 17 and 18 (BUS 1) of the "MO1" of the thermal element M (the bipolar cable already present in
the contacts 17 and 18 must not be removed).
Connect the outgoing bipolar cable from the "MO1" (thermal element M) of the "MANAGING" thermal module into the contacts 21 and
22 (Bus 2) present on the "MO1" of the thermal element D4.
Move the cable in the contacts 17 and 18 (Bus 1) on contacts 19 and 20 (Bus 2).
If you need to connect an additional thermal module, you have to start from contacts 19 and 20 of the "MO1" (element D4) of the
first DEPENDING module, a bipolar cable which will be connected to the terminals 21 and 22 of the "MO1" of the thermal element D8.
