TFI812 - Gas Burner Control Box
For 2-Stage Atmospheric Gas Burners
Possible Flame Detectors:
- Ionisation Probe
- Infra-Red Flicker Detector
The TFI812.2 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 TFI812 Mod.5 Can Be Installed In
Place Of The TFI712 F, And The TFI812 Mod.10 Can Be Employed To Replace
The TFI712.
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 TFI812.1 And
The TFI812.2 Is That The TFI812.2 Control Boxes Are Equipped With The
Voltage Drop Fail-Safe Function. Otherwise, They Are Identical In Terms
Of Operation And Possible Applications.
