Common questions on this part
QRB1-A has standard sensitivity, while QRB1-B has high sensitivity for low-intensity or blue-tinted oil flames.
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.
