5.6 Visualisation and programming modes

The Operator Panel, and especially the display visualisation, has 4 working modes:

It does not require any use of the keys of the Operator Panel.

It allows access to the other visualisation and programming modes.

Some examples in the standard conditions are given below.

The burner is in the request for heat waiting mode, or the selector “0-1” of Fig. 28 is at

the “0” position.

The display visualises the various phases of the start-up, ignition and switch-off of the

burner.

In the example alongside, the display indicates that the burner is in phase 30 (see the

The burner is working in the requested load position (in the example alongside, 78.4%).

The display visualises alternately the error code (in the example alongside, c: 12) and

the relative diagnostic (in the example d: 0).

The system goes into safety mode and the message shown in the next figure appears.

The burner goes into lockout.

The display visualises alternately the lockout code (in the example alongside c: 4) and

the relative diagnostic (in the example d: 3).
