gas burner controllerTFI 812

For two-stage atmospheric gas burner control

Flame detectors available:

-ion probe

-infrared detector

Product Description

• §TFI 812.2 Gas burner controller for controlling and monitoring atmospheric gas combustiondevice. They passedDIN 4788 part 3 edition 04.89 and European standards

EN298Certification and testing. They are also suitable for stationary air heaters.(According to the standardDIN 4794)

• §The controller is designed with the highest safety performance in order to prevent voltage fluctuations. If the LordWhen the voltage drops below the allowable range, the operation will be interrupted and the controller willPrevent the automatic start procedure from repeating.In this way, the security of the system will not be affected.The main voltage is too low and in danger.
• §FR870(NO.70700series)remote reset can be installed and is also allowedRemote reset operation.(ReferenceNo.750File)
• §TFI 812 mod. 5 can be substituted inTFI 712 F, at the same timeTFI 812 mod. 10also canto be used as an alternativeTFI 712.
• §There is no need to rewire or replace the basic base when the product is replaced. ProductsThe height can be varied by lengthening the reset button(No.70601Series)to compensate.
• §TFI 812.1 andTFI 812.2The differenceTF1 812.2With an automatic defenseProtection voltage reduction function. Otherwise, they will be exactly the same regardless of whether they run,Also

Product Description

• §ZT 931The high frequency ignition transformer is suitable for gas burners of any power.ZT 931A relatively large deformation spark can be maintained when the burner power is relatively large or the inlet air speed is relatively high.
• §and is an electronic ignition device that produces minimal electromagnetic interference, which is important for the need to comply with

EN55014The burner is very important.ZT931The current is very low,Power consumption is also low.

• §The power connection is a three-wire connector that is widely used. Transformer coil plug-in can be replaced.
