Description
This microprocessor-based burner management system controls automatic ignition, flame monitoring, and safe shutdown for gas or oil burners. It supports two-stage operation with an intermittent cycle and uses ionization flame detection by rectification. The system reacts to flame loss in less than 1 second, incorporates false flame check, pre-purge, air pressure switch verification, and can drive modulation actuators. It features manual reset lockout and complies with EN 298.
Further details
| Air supply | natural draft and forced air supply |
|---|---|
| Air supply compatibility | Natural draft (without fan) and forced air supply (with fan) |
| Application Type | automatic ignition control, flame monitoring, and safe operation of atmospheric gas burners |
| Automatic sequence | check for absence of false flame → pre-purge → ignition on first stage → ramp to full power (if needed) → combustion monitoring → safe shutdown upon flame loss |
| Burner configuration supported | natural draft (without fan) and forced air supply (with fan in combustion circuit) |
| Connection pattern requirement | base or plug must match burner harness |
| Control features | Sequential start of the first and second power stages, optimizing fuel consumption and ensuring smooth thermal power regulation |
| Control functions | energise fan for pre-purge, verify airflow via air pressure switch, initiate spark from ignition transformer, open fuel valve, prove flame within safety time |
| Fuel efficiency benefit | saves fuel and reduces number of starts/stops |
| Interchangeability | Controls of different series are normally not interchangeable, even within the same brand |
| Interchangeability restriction | controls of different series are not interchangeable; mismatched safety times create safety hazard |
| Replacement guidance | Verify markings on the original unit and match the series, voltage, timing, and flame detection type exactly |
Choosing and fitting
Replacement controls of this type are selected by exact series and type designation, supply voltage, safety and pre-purge times, and flame detection method (ionisation, UV, or IR). The physical connection pattern (base or plug) must match the burner harness. Different series are normally not interchangeable even within the same brand; using a unit with mismatched safety times creates a safety hazard. Before ordering, verify the markings on the original unit and match series, voltage, timing, and flame detection type exactly.
Signs of failure
Typical failure modes include lockout when flame is not detected, repeated lockouts during operation, and failure to complete the pre-purge or ignition sequence. The equipment may fail to start, shut down on flame loss, or remain in manual reset lockout. Check the ionization electrode, wiring, and that the control box matches the burner's series, voltage, timing, and flame detection method.
