* 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 the following INST
parameter on all connected burners:
PAR 15 =
0 for the first boiler (MASTER)
1 .... 7 for the other boilers (SLAVE)
(Avoid assigning the same number to SLAVE boilers)
Set the following INST parameter if polypropylene smoke collectors
with a clapet valve are used in sequence/cascade installations:
PAR 1 =
61 (for NATURAL GAS boilers)
63 (for PROPANE boilers)
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 (
