It works with Siemens LMO14, LMO24, LMO44, LME11, LME21, and LME22 control boxes.

It comes with a 500 mm heat-resistant flexible connection cable.

A dirty glass lens, incorrect positioning, faulty flame ignition, or a burnt-out sensor element will trigger a lockout.

Measure resistance with a multimeter: it should show high resistance in total darkness (> 1 MΩ) and low resistance in light (< 5 kΩ).

It has an IP40 rating and should be protected from direct water spray inside the burner housing.

Manufactured by Siemens Building Technologies in Germany.
