SETTINGS
All settings have already been made in the factory. If the boiler needs new settings after repairs have been made, the
gas valve changed, or after a conversion from methane to LPG, proceed as follows.
b
The settings for minimum fan speed, maximum CH fan speed, maximum DHW fan speed, and ignition slow fan
speed must be made in the sequence given and must only be made by qualified personnel.
b
Proceed as follows to activate the "combustion analysis" function:
- Switch off the system
- Disconnect the communication cable between the CH circuit (BAG) control card and the boiler control card
- Switch the system on again and perform the regulation procedure with the direct zone requesting heat in
order to dissipate heat from the mixing column.
