MMI 962.1 Mod 23 230v Control Box
Gas Burner Automatic Safety Control
• For power gas burners
• Terminals for air damper motor
• Built-in remote reset for lock-outs
- Possible flame detectors:
- Ionization probe
- Infrared flicker detector
The gas burner automatic safety control MMI 962.1 controls and monitors blown gas- and combined burners of any nominal thermal load (tested and certified according to EN 298).
If an air damper unit is connected, a 2-stage operation with two fuel valves or a modulating operation with one fuel valve is possible.
Various types and model designations differentiate the automatic safety controls with respect to the programme times, as well as with regard to differing national standards. The control box type MMI 962.1 Mod. 23 can be used instead of the types MMI 812 Mod. 23 or MMI 812.1 Mod. 23.
