OBC 85

The OBC series offers stable and precise timings independent of variations in supply voltage and ambient temperature. The control is undervoltage protected in accordance with EN 298:2012. In case of undervoltage 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. OBC 85 offers 1 and 2 stage and post purge.
