Having configured he master boiler parameters as described in the previous paragraph, proceed to configuration of the other
boilers. To this purpose, connect the Remote Control (if not already present) to the boiler to be configured and proceed as
follows.
The operations listed below are repeated for each boiler in the cascade, excluding the MASTER boiler.
For correct system functioning an address must be assigned to each boiler so that it can be recognised by the master boiler (the
master boiler has default =1). Moreover it is also necessary to synchronise the boiler clocks with that of the master boiler. Using
the control panel, access menu 3 and carry out the following settings.
