For 1- or 2-stage oil burners up to 30 kg/h throughput and intermittent operation with or without oil preheating

Flame detection:

Photo resistor MZ 770 S Infrared-flicker detector IRD 1010 UV flame sensor UVD 970

The TF 974 or TF 976 oil burner safety control boxes are suitable for oil burners which may be equipped with a oil preheater up to 30 kg/h capacity. The control boxes are approved and certified according to EN 230.
A special contact in the control unit short-circuits the thermo-switch of the fuel heater as soon as the burner is operating and the flame signal is present. Therefore interruption of the burner operation due to decreasing oil temperature can be prevented (e.g. in case of high oil flow).
If the control box goes into lock-out mode, the oil preheater power supply is also disconnected.
