We have a Danks of Nerthalands boiler having a Landis & Gyr LEC 1 sequence timer that is not firing the boiler. The flame amplifier and a QRB photocell are new. It goes the entire 60 minutes and goes back to the origin. What could be the problem? Do we have Landis and Gyr equivalents?

Its DANKS OF NETHERTON actually!

Is the Control Box Going to Lockout, or does it keep cycling round and round? if so it souns like the control is not getting a control signal from the air damper servo-motor, or the box may be faulty, Satronic TMO 740 would be a suitable repalcement with an MZ770 Photocell, but the whole control would need rewiring
