MACHINE OPERATING CODES
If, during the operation of the appliance, the display of the controller of the appliance
(or also of the display of the Direct Digital Controller, if connected) signals an operating
code, it is necessary to:
make a note of the indications shown on the display;
•
consult the (specific) list of machine operating codes.
•
For the operating codes generated by the controller of the appliance, refer to Ta-
ble 8.1 TABLE OF OPERATING CODES generated by the controller (firmware version
3.100)
→
77. If the appliance is connected to a DDC, a list of the operating codes gene-
rated by the DDC is provided in the DDC's manual (see "installation technician manual
- manual 1").
carry out the instructions contained in it scrupulously (contact your Authorised
•
Robur Technical Assistance Centre when instructed to do so).
If, after performing these operations, the appliance does not start, first carry out the
following simple checks:
ensure that the external disconnecting switch fitted by the electrical installation
•
technician on a suitable panel (see Section 5 ELECTRICAL SYSTEM INSTALLATION
TECHNICIAN
→
41) is set to ON;
check that the consent switches (see Paragraph 5.3 CONNECTIONS FOR CON-
•
SENT SWITCH OPERATION
→
50) or the DDC (if connected and in controller mo-
de) are set for operation of the appliance;
check that the gas supply valve is open;
•
determine that no further indications are given on the display.
•
At this point, if the appliance still does not start:
refrain from proceeding by trial and error; instead request the direct assistance
•
of an authorised Robur Technical Assistance Centre (TAC), informing it of the
Machine Code that has arisen;
disconnect the appliance from the gas and electricity supply, cutting off the gas
•
supply by means of the appropriate tap and electrical power via the external
master power switch. Wait for the TAC staff to arrive.
For how to reset the machine operating code with the on-board controller, refer to
Paragraph 3.3 RESET OPERATIONS

21.
We list below the operating codes generated by the appliance's controller (firmware
version 3.101). The following codes can also be displayed by the DDC, if connected.
