Where Are These Control Boxes Used?
Let’s consider the MM192N—a perfect fit for industrial gas burners on heating lines or firing kilns due to its compatibility with fans, external ignition, and remote reset capabilities. It offers precise control over ignition cycles in a manufacturing environment with safety redundancy built-in.
On the other hand, CM191N is suitable for a standard domestic gas boiler, such as those in small apartment buildings or homes. It supports a simpler configuration—ideal for maintenance teams looking for ease of use and reliability.
Models such as the SM152N can be configured for equipment with intermittent pilot systems, thanks to auxiliary contact support and variable safety timing parameters. For example, if used with an Ecoflam diesel air heater, the configuration may be tailored on request to match ignition cycles and spark frequency.
⚠️ Note: These boxes are not suitable for oil burners, diesel heaters, or systems using actuators like Siemens, Modutrol, or Kromschroeder, which are typically found in gas valve trains.
Practical Installation Advantages
- Configurable with different socket types: NG, MG, P, R
- Optional reset button or side-mounting brackets
- Ready for remote diagnostics and LED lockout indication
- Designed to meet strict European safety standards
