Main features
- EMC filter on the board. Protection fuse on the board.
- Stable timers not affected by the voltage and/or temperature changes (system management by microproces-
sor).
- Protection in case of low/high voltage power supply.
- Monitoring of air pressure switch functioning. Non-volatile block. remote reset;
- Intermittent functioning: regulation and self-diagnosis stop every 24h. As a rule at least once every 24 hours
to allow the electrical equipment to check its efficiency at start-up. Normally burner shutdown is ensured by
the boiler remote control. Otherwise it is necessary to install a time switch in series that provides for burner
shutdown at least once every 24 hours.
- Air damper control for functioning at several stages or modulating.
- Built-in button or two-colour LED for indicating functioning status and anomalies;
- Safety valve sealing control function.
