The special key allows the knob of the electronic board to be operated without opening
the cover of the electrical panel, so that operators are protected from live components.
When the necessary settings have been completed, put away the special key, replace the
cap on the aperture of the electrical panel and refit the front panel of the appliance.
4.3 RESET OPERATIONS
There are several possible reasons why the appliance may have error status and therefore
its operation arrested; such an error situation does not necessarily correspond to damage
or malfunction on the part of the appliance. The cause that has generated the error may
be temporary: for example, presence of air in the gas supply line or temporary power
failure.
The appliance can be reset with controller menu 2, the Comfort Control Panel (if present)
or the DDC (if present). In these two latter cases, refer to their documentation.

The general operating codes of the unit's controller can be reset with actions "0" and "1".
Actions "3", "4" and "5" are used to regulate the combustion parameters or for gas type
changeovers, and are thus for use only by the installation technician or Robur TAC (for
other information refer to Paragraph 7.1 PROCEDURE FOR FIRST START UP → 73).
RESET FLAME CONTROLLER (ACTION "0"):
Reset flame controller arrest; this may be used when the appliance is first activated, see
Paragraph 4.1 START UP (AND SHUT DOWN) → 17, when the appliance is in a permanent
locked condition or after a long period of disuse (see Paragraph 4.5 PROLONGED PERI-
ODS OF DISUSE → 24).
