What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Description

This microprocessor-based electronic control board is designed for wall-hung boilers. It uses ionisation or other flame detection and incorporates complete safety algorithms; on flame failure it goes to lockout. The board is manufactured by Honeywell in the USA/Germany. Its model is SM11472, with SKU SM11472U and article number 711050800.

Further details

Actuator control	fan, gas valve, ignition transformer, pump
Application	boiler equipment, gas burners, ventilation systems (HVAC)
Control Functions	ignition sequence, safety times (pre-purge, ignition, fuel admission, flame proving)
Control operations	run the ignition sequence, enforce safety times
Installation feature	must be matched exactly to the boiler model
Interchangeability	not interchangeable across different boiler series, even within the same brand
Output Drives	fan, gas valve, ignition transformer, pump
Sensing Inputs	flame signal, pressure switches, temperature sensors

Choosing and fitting

Control boards of this type must be matched exactly to the boiler model; they are generally not interchangeable across boiler series, even within the same brand. Selection is made by the original part number or the manufacturer's specific code, cross-referenced against the boiler's documentation. No additional specifications such as voltage or dimensions are available, so the board should be ordered only after confirming the exact replacement for the equipment.

Signs of failure

When a control board of this kind fails, the equipment may show an error, fail to respond to commands, or operate intermittently. The board monitors sensors and enforces safety algorithms; upon detecting a fault, it goes into lockout. Checking the board itself for correct processing of pressure, temperature, and flame-ionisation signals can help identify the cause.
