Burner Program Controller
Zhongli Weiye supplies burner program controllers matched by type code, flame detection method and supervision logic to the burner they have to run.
What the program controller does
The program controller, also called a burner control box or flame safeguard, is the sequencing brain of the burner. It runs the pre-purge, ignition, flame proving and post-purge steps, supervises the flame signal throughout, and locks the burner out if any step of the sequence fails. Every start attempt, lockout and reset passes through it, which is why it is the first place a technician looks when a burner will not fire.
Controllers are not interchangeable across brands or series. The flame detection method (ionisation probe, ultraviolet cell or infrared flicker), the supervision timing, the wiring base and the supply voltage all have to match the burner and the detector the controller supervises. Fitting a controller with the right plug but the wrong supervision logic gives you a burner that starts and then locks out intermittently, which is far harder to trace than a dead unit.
- Match these before ordering: flame detection method, supply voltage and frequency, wiring base or sub-base, and the burner series it was supplied with.
- For a replacement, send the controller type code, the burner model and the lockout indication you are seeing.

Controller FAQs
Can I fit a different brand of control box to my burner?
Only where the detection method, timing and wiring have been matched to the burner — and usually the answer is to stay with the series the burner was built for. Send us the burner model and the controller code on the failed unit and we will confirm the correct replacement.
My burner starts and then locks out intermittently — is the controller faulty?
Not necessarily. Intermittent lockouts are more often a flame-signal problem: a dirty or misaligned detector, an ignition cable leaking high voltage into the probe circuit, or poor earthing. Work through those before replacing the controller.
