Description
Honeywell TFI 812.2 model 10 02602U Gas burner control box
The gas burner control box TFI 812.2 controls and monitors atmospheric gas burners.
Moreover, it can also be used at stationary warm-air generators according to DIN 4794.
Replaces: TFI 712-1, TFI 712
Introduction:
The TFI 812.2 gas burner control boxes are capable of controlling and monitoring atmospheric gas burners. They have been tested and approved as per DIN 4788 part 3 edition 04.89 and with the European standard EN 298. They are also suitable for use with stationary warm air generators (as per DIN 4794). The control boxes are designed for maximum safety in case of fluctuations in the voltage supply. If the mains voltage drops below the permitted level, operation is interrupted and the control box automatically prevents the start sequence from being repeated. In this way, the safety of the system is not put at risk by a drop in the mains voltage. The control box and the monitoring function which it performs is not negatively affected by occasional stray ignition sparks jumping to the ionisation electrode. The FR 870 remote reset (item no. 70700) can be connected, and allows remote reset of the control box (see doc. no. 750). The TFI 812 mod.5 can be installed in place of the TFI 712 F, and the TFI 812 mod.10 can be employed to replace the TFI 712. It is not necessary to rewire or replace the baseplate. The difference in the heights of the units can be compensated by attaching the reset button extension (item no. 70601). The difference between the TFI 812.1 and the TFI 812.2 is that the TFI 812.2 control boxes are equipped with the voltage drop fail-safe function. Otherwise, they are identical in terms of operation and possible applications.
