Description
This microprocessor-based control box automatically manages the start-up, flame monitoring, and safe shutdown of gas and oil burners with modulating stages. It is rated for 220–240 V supply voltage, 50–60 Hz frequency, and 30 W power consumption, with a built-in 4 A fuse. The pre-purge time is 60 s, the safety time is 4 s, and the waiting time is 60 s. A photodetector monitors the flame, and on flame loss the reaction time is less than 1 second. The device has an impact-resistant plastic housing, protection class IP00, weighs 0.2 kg, and measures 107 x 81 x 36 mm; it also includes a built-in ignition transformer and two safety contacts.
Further details
| Application | heating, steam and combination boilers; air heaters and hot air guns; furnaces, water heaters and other process equipment |
|---|---|
| Correct phase/neutral wiring required | phase and neutral must be connected correctly |
| Grounding required | proper earthing of control unit, burner metal housing and mains supply |
| Operating sequence | Thermostat closes -> fan pre-purge -> ignition transformer and gas valve energised -> flame signal checked within 4 s -> stable operation or lockout; manual reset; forced restart every 24 h |
| Reset method | manual button or electric (power interruption) |
| Varistor | protects controller against mains voltage surges |
