Description
This is an automatic control box for two-stage, forced-draft burners operating on gas or gas-oil combinations. It runs on 220/240 V (-15...+10%), 50-60 Hz, and draws 10 W. Its timing sequence provides a 5 s safety time, 24 s pre-purge time, and 8 s pre-ignition time, and it supports flame detector cable lengths up to 20 m. The unit uses ionization or infrared flame detection (IRD 1020), and is enclosed in a transparent, non-flammable plastic removable casing rated IP44 for ambient temperatures from -20 to +60 °C.
