Maintenance optimisation
A maintenance message may be generated that does not set the boiler 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.
•
Operating hours of the burner (parameter 7040).
•
Number of starts (parameter 7042)
These last 2 parameters are dependent on the boiler's hydraulic installation. We recommend
using at least parameter 7044 for annual maintenance.
IMPORTANT:
In diagram VF21, it is IMPERATIVE to programme the same ranges
on the unit heater for the optimisation to work.
