ure/setting it is a command, a flashing code is displayed
(e.g. "reS1" for the flame lock-out reset command).
9. Press the knob to reconfirm the figure; or rotate the knob
to modify the figure, and press at the end to confirm or
set the new figure; if however, it is a matter of controlling
an appliance operation, press the knob to execute it.

MODIFYING SETTINGS
Modify the settings through the DDC or CCP/CCI
If the appliance is connected to the DDC or to the CCP/
CCI control, refer to the relevant manual to modify
settings.
5.3.1
How to raise/lower the water temperature
setpoint
The water temperature set-point establishes the outlet
temperature to the system (water output from the appliance), or
inlet from the system (water input in the appliance). The temper-
ature is pre-set by the TAC upon first start-up.
If the appliance is not connected to a DDC or CCP/CCI
control, to raise/lower the water temperature set-point
with the S61 board, proceed as follows:
1. Access menu 3 under parameter 161 (= water tempera-
ture set-point) by rotating and pressing the knob; "3.161"
must be displayed (procedure Paragraph 5.2
2. Display the parameter value by pressing the knob; the
previously set value is displayed (from 10 to 65 °C); to
reconfirm the pre-existing value press the knob again,
otherwise go to step 3.
3. Turn the knob to modify the value, increasing or decreas-
ing it, and press it to set the new value.
4. Exit menu 3, and from the menu list, by selecting and
pressing letter "E" twice, and go back to the normal dis-
play of detected temperature data.
Do not modify complex settings
Specific technical and system knowledge is required for
complex settings. Contact a TAC.

NORMAL OPERATION
This section is for the end user.
The use of the device by the end user is only per-
mitted after the Robur authorised TAC has completed
the first start-up.
6.1
WARNINGS
General warnings
Prior to using the appliance carefully read the warnings
in Chapter III.1
p. 4, providing important information
on regulations and on safety.
First startup by TAC
First start-up may exclusively be carried out by a Robur
TAC (Chapter 5
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.1
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.
Checks before switching on
Before switching on the appliance, ensue that:
gas valve open
appliance electrical power supply (main switch (GS) ON)
DDC or CCP/CCI power supply (if present)
water circuit ready
6.2.1
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, timer, switch, ... 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 immediately, but
it will only start when there are actual service demands.
