6�1 WARNINGS
General warnings
Prior to using the appliance carefully read the warnings
in Chapter III p. 4, providing important information
on regulations and on safety.
First start-up by TAC
First start-up may exclusively be carried out by a Robur
TAC (Chapter 5 p. 31).
Never power the appliance off while it is running
NEVER power the appliance off while it is running (ex-
cept in the event of danger, Chapter III p. 4), since
the appliance or system might be damaged.
6�2 SWITCH ON AND OFF
Routine switching on/off
The appliance may exclusively be switched on/off by
means of the suitably provided control device (DDC,
CCP/CCI or external requests).
Do not Switch On/Off with the power supply switch
Do not switch the appliance on/off with the power sup-
ply switch. This may be harmful and dangerous for the
appliance and for the system.
Inspections before switching on
Before switching on the appliance, ensue that:
▶
gas cock open;
▶
appliance electrical power supply (main switch (GS)
ON);
▶
DDC or CCP/CCI power supply (if present);
▶
water circuit ready.
How to switch on/off
▶
If the appliance is controlled by a DDC or by a CCP/CCI (sys-
tems (1) and (2) see Paragraph 1.7 p. 16), refer to the re-
spective manuals.
▶
If the appliance is controlled by external request (e.g. ther-
mostat, clock, button, ... with voltage-free NO contact), (sys-
tem (3) see Paragraph 1.7 p. 16), the appliance is switched
on/off by the ON/OFF positions of the external control de-
vice.
After switching on with the control, in normal operating condi-
tions, the appliance starts/stops automatically according to the
user's thermal needs, supplying hot water at the programmed
temperature.
Although the external request is in the "ON" position,
this does not mean the appliance will start immedi-
ately, but it will only start when there are actual service
demands.
