RANGE RATED CERTIFICATION
The maximum power, in heating mode, of
MURELLE.HT
boilers
can be adapted, during the installation, to the thermal needs
of the system by modifying the setting of PAR 19 in the
0 .. 100
range.
The setting of PAR 19 = 100 is the factory setting that allows
the boiler to deliver its maximum power in heating mode. It can
be reduced by modifying the setting of PAR 19 as shown in the
table appearing below.
Once the new setting of PAR 19 has been made, the reduced
maximum power value (kW) MUST MANDATORILY be applied
beside the boiler’s data plate. For checks and adjustments af-
ter the modification, refer to the new value for the maximum
power.
The useful nominal power levels used are those relative to the
operating conditions (80-60°C) (Pn min - Pn max).
Example for
MURELLE.HT 25
boiler:
– default heating power range: 1,65 - 24,2 setting of PAR 19 = 100
– “reduced” heating power range: 1,65 - 19,7 setting PAR 19 = 80
