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.
