Heating Capacity Adjustment (RANGE RATED)
This is a "RANGE RATED" boiler (according to EN 15502) and can be adjusted to the system's thermal re-
A
quirement by setting the maximum heating capacity for operation in heating mode, as follows:
• Put the boiler in TEST mode (see sec. 3.1).
• Press the contextual buttons 1 and 2 to increase or decrease the heating capacity (minimum = 00 - maximum =
100). See the diagram "Heating Capacity Adjustment" (fig. 84).
• By pressing the OK button (detail 6 - fig. 1) the maximum heating capacity will remain that just set. Exit TEST mode
(see sec. 3.1).
After setting the desired heating capacity, write the value on the sticker provided and place it on the boiler under the
data plate. For subsequent checks and adjustments, refer to the set value.

TECHNICAL MENU

ONLY QUALIFIED PERSONNEL CAN ACCESS THE SERVICE MENU AND MODIFY PARAMETERS.
Accessing the Technical Menu is only possible after entering the code 4 1 8. It is valid for 15 minutes.
To copy a parameter to the other boiler modules, se-
lect the parameter from the list, press OK to enter the
parameter and then press the button ECO/COMF
(fig. 85). In this way the parameter is replicated on all
modules.
It is advisable to make the various modu-
A
les work with the same parameter values,
in order to have optimal balance of the
working point.
