Maintenance optimisation:
It is possible to generate a maintenance message without harming the boiler. This maintenance
message may appear when the 3 following meters have elapsed:
• Time since last maintenance (or commissioning): set parameter 7044 to 12 months
• Operating hours of the burner (parameter 7040)
• Number of start-ups (parameter 7042)
The last 2 parameters depend on the boiler room's hydraulic installation. It is recommended to
use at least parameter 7044 for yearly maintenance.
