ALHENA C
Heat Capacity Adjustment (RANGE RATED)
THIS OPERATION MUST BE PERFORMED ONLY BY QUALIFIED PERSONNEL.
This is a "RANGE RATED" boiler (according to EN 15502-1:2022) and can be adjusted
A
to the system's thermal requirement by setting the maximum heat capacity for operation
in heating mode.
To set the maximum heat capacity reachable, it is necessary to change parameter P41. To chan-
ge this parameter, see "Service menu" on page 274.
Set the value of parameter P41 according to the indications of table 10.
