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.
Warning
the boiler considers a heat demand for a voltage H1> 0.2 V and a resulting setpoint> 6 ° C *.
The boiler no longer considers a heat demand for a voltage H1 <0.2V or a resulting setpoint <4 ° C *.
In this second case, the boiler isolation valve will close. If the installation does not include a hydraulic
decoupling bottle, all the network pumps must be stopped at the risk of causing them to cavitate.
* : according to scale given in parameter "5956"
