3) Confirm the selection by pressing the
Degrees Button

4) Press the
Scroll Buttons
to set the minimum activation temperature for the sensor. The sensor is installed in the central
part of the boiler tube and commands the appliance to start the boiler if it is off. On the other hand if the appliance is
operating, it commands the diverting valve as the available heat inside it is coming to an end. The setting range is from
45°C to 65°C.
5) Confirm the selection by pressing the
Degrees Button
and the following screen will appear.
6) Press the
Scroll Buttons
to set the maximum activation temperature for the sensor. The sensor commands the appliance
to shut off if it is ON, whereas if the appliance is operating, it commands the diverting valve as the boiler tube is satisfied.
The setting range is from 49°C to 75°C.
Attention: The maximum temperature will always exceed, by at least 4°C, the minimum set temperature.
7) Confirm the selection by pressing the Degrees Button followed by the Menu Button.
At this point the appliance operating status will appear on the display.
To
disable
the THERMO ACS unction simply repeat operations 1 and 2 selecting the OFF command. The function will be disabled
immediately.
When this function is activated the appliance operates at the automatic power (see para. 6.10.3) when the domestic hot water boiler
tube is requesting heat, it then reverts back to the power selected by the user when the boiler is satisfied.
ATTENTION:
The boiler tube must have at least a 300 litre capacity.
If the optional sensor is not connected to the appliance or if it is interrupted, it will not be possible to activate this
function.
Pay special attention to the number of ON/OFF cycles that the appliance is subjected to with this function. It is
recommended not to exceed three ON/OFF cycles. If the startups are frequent and repeated it is possible that the the
generator will fail to st
art and the following error message appear: “Failed start – Clean burner” (see para. 10). The
appearance of this message is not attributable to a product defect but is caused by a brazier that requires cleaning as
described in this manual in chapter entitl
ed: “Troubleshooting – Possible Causes – Solutions”.
ATTENTION: If the programmed time schedule is enabled (a clock symbol appears on the display) the appliance will
follow exclusively the preset ON and OFF times. No request for heat from the boiler or system will be considered by the
appliance outside the programmed time interval and the texts WAIT TIME or NO PROGRAM will appear on the display
(see para. 6.10).
ATTENTION: If an external chronothermostat is connected to the appliance, the appliance will follow it exclusively. No
request for heat from the boiler tube or system will be considered by the appliance appliance if the external
chronothermostat does not give consent and the text WAIT TIME appears on the display (see para. 6.10).
When
ACS ON
is activated the shower symbol with the temperature detected by the sensor will appear on the display. The shower
symbol will flash if the boiler tube requesting heat, whereas it will remain steady if the boiler tube is satisfied.
