WARNINGS AND ERRORS
If, during the operation of the appliance, the display of the electronic board of the
appliance (or also of the display of the Direct Digital Controller, if connected) signals an
operating code, it is necessary to:
- take note of the indications shown on the display;
- consult the (specific) list of the operating codes;
For a list of the operating codes generated by the S61 electronic board,
refer to Table 27 on page 96.
If the appliance is connected to a DDC, a list of the operating codes
generated by the DDC is provided in the DDC’s manual (see "installation
technician manual – book 1");
- follow the instructions given in it strictly (contacting the authorized Robur Technical
Assistance Centre, "TAC", when required).
If, after these operations have been carried out, the appliance does not start, first perform
the following simple checks:
- verify that the on/off command controls (CS, W/Y: see Figure 18 on page 53) or that
the DDC (if connected and in controller mode) are in such a position as to require the
operation of the appliance;
- ensure that the external disconnecting switch fitted by the electrical installation
technician on a suitable panel (GS: see Figure 17, Figure 19 and Figure 20 from page
53 to 55) is in the "ON" position;
- check that the gas supply valve is open;
- verify that there are no further indications given on the display.
At this point, if the appliance still fails to start:
