RANGE RATED
This boiler can be adapted to the heating requirements of the sys-
tem, in fact it is possible to set the maximum delivery for heating
operation of the boiler itself:
- switch off the power supply
- setting the heating water temperature selector at the maximum
value
- remove the shell
- turning the instrument panel towards you
- unscrew the two screws of the small cover on the electronic
board to have access to the terminals
- insert JP1 jumper
- power up the boiler
The display shows "ADJ" for about 4 sec.: it is then possible to
change the maximum heating value by means of the heating water
temperature selector and the CO button in order to set and confirm
the desired value.
The icon will appear on the display.
Finish the procedure by removing the jumper JP1 to store
the set values.
Once the desired output (maximum heating) has been set, note the
value on the table on the back cover.
For subsequent controls and adjustments, refer to the set value.
The calibration does not entail the ignition of the boiler. By ro-
tating the heating setpoint selector knob, the value expressed
in hundreds (e.g. 25 = 2500 rpm) is automatically displayed.
The boiler is supplied with the adjustments shown in the table.
Depending on plant engineering requirements or regional flue gas
emission limits it is, however, possible to modify this value, refer-
ring to the graphs below.
