Description
This Honeywell control box is designed for two-stage forced draught oil/gas burners and is approved as per EN 298. It operates on a supply voltage of 220–240 V AC at 50–60 Hz, with a power consumption of 10 W. Its timing schedule includes a 6 s waiting time, a 55 s pre-purge time, a 5.5 s pre-ignition time, and a 3 s safety time. It supports ionisation probes, UV sensors, and the IRD 1020 infrared detector. For ionisation or UV sensing, the minimum required current is 5 µA. The control box is rated IP44, may be mounted in any position, and is certified for ambient temperatures between -20 and +60 °C.
