PAR DESCRIPTION
49 * Reset default parameters
(par 01 - par 02 = "-")
* In case of difficulty in understanding the current setting or in case of an anomalous or
incomprehensible conduct of the boiler, we suggest to restore the initial values of the parameters
setting PAR 49 = 1 and the PAR 1 and PAR 2 as specified at point 3.3.1.
CASCADE CONNECTION PARAMETERS
When the appliance is installed in sequence/cascade (modular
system with several generators) it is necessary to set on all the
boilers the following INST PAR parameters:
PAR 15 =
Set the following INST parameter if polypropylene smoke collec-
tors with a clapet valve are used in sequence/cascade installa-
tions:

In addition, when the number of boilers in cascade is more than
two, configure the parameters OEM A1 of the MASTER boiler.
To access the OEM parameters press simultaneously the buttons
