In all the presented configurations, if a Remote Control or a room unit is used, set them to room unit 1 in order to manage the
DHW functions and the boiler stand- by, as well heating zone 1. If they are set as room unit 2 or room unit 3 only heating zones
2 and 3 respectively can be managed. See the instructions manual of the respective accessories for the configuration procedure.
After each system configuration process, carry out the following procedure for saving the components to the boiler.
• Access menu 2 as indicated at the beginning of this section.
• B Configuration
• B Yes then B to confirm.

5. APPLICATION OF THE BOILERS IN A CASCADE ARRANGEMENT

To manage the system correctly, edit the parameters of all the cascade boilers. The first boiler to configure is the MASTER boiler.

5.2

CONFIGURING PARAMETERS ON A NON-MASTER BOILER

After configuring the the parameters of the master boiler, as described in the previous section, move on to the other boilers. For
this purpose, connect the Remote Control (if not already present) to the boiler to configure and proceed as follows.
The following operations must be repeated for each boiler in the cascade, except for the MASTER boiler.
To ensure the system works correctly, assign an address to each boiler so that they can be recognised by the master boiler (the
default address of the master boiler =1). The clock of each boiler must be synchronised with that of the master boiler. Enter menu
3 from the control panel, as described in section 4, and make the settings shown in the following table:
