Maintenance optimisation
A maintenance message may be generated that does not set the generator to fault. This maintenance
message may be displayed after the following 3 counters have expired:
• Time since last maintenance (or commissioning): set parameter 7044 to 12 months
(Maintenance / Special regime menu)
• Burner's operating hours (parameter 7040 - menu Maintenance / Special regime menu)
• Number of starts (parameter 7042 - menu Maintenance / Special regime menu)
These last 2 parameters are dependent on the boiler's hydraulic installation. We recommend
using at least parameter 7044 for annual maintenance.
