General

The microprocessor based control OBC 82.11 offers stable and precise timings independent of variations in supply voltage and ambient temperature. The control is under voltage protected in accordance with EN 298:2012. In case of under voltage the control will prevent the burner from starting and simultaneously show a flash code. Besides this, up to five other fault types can be read out as flash codes when the control is in lockout. The design complies with the requirements of the RoHS and WEEE directive..
