8. Heating capacity controller (see fig. 27, item 8)
This controller is to set the maximum load. The highest
setting corresponds to a maximum load of 100 % and
the lowest setting corresponds to a maximum load of
30 %.
9. DHW temperature controller / Service capacity
controller (see fig. 27, item 9)
The function of DHW temperature controller is not
applicable to this boiler. The function that remains is that
of Service capacity controller. This allows you to adjust
the boiler's capacity while in Service mode.
Set boiler to Service mode by setting the Chimney
sweep switch to '1', then press the Service button until a
'Y' can be seen in the display. Now you can adjust the
service heating capacity of the boiler. The setting is only
valid during Service Mode.
10. Flow temperature controller (see fig. 27,
item 10)
This controller with the radiator symbol allows the
installer to set the maximum flow temperature (see
table 4 on page 36).
2.2.4 Checking the gas type
It is very important that the gas type to which the boiler
will be connected corresponds to the gas type the boiler
is equipped with. If this is not the case, then the boiler
must not be put into operation.
Check the gas type with your gas supplier and
compare this to the boiler's gas type as registered on
the identfication tag (see table 3).
It is possible to change the boiler to another gas type
(see table 2). This accessory can be ordered from your
supplier.
CAUTION
The burner must only be put into operation
with the correct nozzles (table 3).
CAUTION!
Subject to modifications resulting from technical improvements!
