How to identify the correct Control board

The PCB coordinates functions of the equipment through its inputs, outputs and circuits of Control. To choose a Replacement part, it is interesting to identify the complete revision and how it connects to the Boiler, in addition to the commercial name.

In this unit there are three black relays mounted and a fourth position without relay. That distribution helps to distinguish it from other cards on the same platform. SYMSI7.0 is the screen printing of the Circuit: by itself it does not identify all revisions nor does it prove that any PCB with that marking is interchangeable.

Model listed in the catalogue

This tab is catalogued for Saunier Duval Isotwin F28-EA. The photo unit is visually identified by SYMSI7.0 and three installed relays. Before replacing it, it contrasts the service reference and configuration with the cutting of the exact variant of your Boiler.

The model shown comes from the identification of this sheet. It does not constitute a list of other compatible Boilerss nor does it prove equivalence with all SYMSI7.0 revisions.

Before replacing the part

Identification of this unit

Set the number of relays mounted, the connector positions, the Circuit cuts and the complete labels on both sides. Keep the PCB identification removed and the complete Boiler model to see its cutting.

Before replacing the Part

A Boiler that does not boot may have a power problem, sensors or other components. The diagnosis must precede the replacement of the Control board.

Service in Madrid and surrounding areas

Do you need us to install it?

We repair boilers in Madrid and the surrounding areas. Installation is arranged separately from the purchase of the part.

Questions about this spare part

Is it enough that two plates have the same connectors?

No. The applicable reference, revision and configuration provided by the manufacturer for the equipment must also coincide. The appearance and connectors help to rule out differences, but do not replace that identification.

What identifies the SYMSI7.0 marking of this PCB?

It is the visible screen printing on the impreso circuit. It serves to recognize the electronic platform, but does not replace the service reference nor confirms compatibility with all Boilerss that use cards of similar appearance.

How many relays does the unit have photographed?

Three black relays installed and a fourth position without relay are observed. Compare this configuration to the original unit; equivalence with four relay versions is not assumed.
