产品介绍

TF834.3/836.3 - Oil Burner Safety Control

For 1- or 2-stage oil power burners up to 30kg/h capacity with or without oil preheater and intermittent operations.

Flame detection:

- Photoresistor MZ 770 S

- Infrared-flicker detector IRD 1010

- UV solid state sensor UVD 970

A special contact in the control unit short-circuits the thermo-switch of the oil preheater as soon as the burner is operating and the flame signal is present. Therefore interruption of the burner due to decreasing oil temperature (e.g. in case of high oil flow) can be prevented.

If the control box goes into lock-out mode, the oil preheater power supply is also disconnected.
