To
deactivate
ACS SUMMER function simply repeat operations 1 and 2 in this paragraph, but this time select the OFF command.
The function will be disabled immediately.
ATTENTION:
If the optional sensor is not connected to the appliance or is interrupted, it will not be possible to activate this function.
ATTENTION
The boiler tube must have at least a 300 litre capacity.
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.
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 tube will be considered by the
appliance outside the programmed time interval and the texts WAIT TIME or NO PROGRAM will appear on the display.
ATTENTION: If an external chronothermostat is connected to the appliance, the appliance will follow it exclusively. No
request for heat from the puffer will be considered by the appliance if the external chronothermostat does not give
consent and the text WAIT TIME appears on the display.
ATTENTION: When ACS SUMMER is set the appliance will start up and shut off autonomously and only according to
the temperature setting of the boiler tube and the actual temperature detected.
When is it important to use the ACS SUMMER function?
In systems configured like the nearby diagram, where the appliance is connected
directly to a domestic hot water boiler tube and to the system.
Using this function the generator starts up automatically when the boiler tube is
running out of heat and only in the programmed time bands.
Once the boiler tube is satisfied, the appliance does not supply heat to the system
and shuts OFF.

block CN5 on the electronic board (see para. 11), the temperature of the room where the sensor will be placed.
ATTENTION:
If the optional sensor is not connected to the appliance or if it is interrupted, it will not be possible to view and
consequently activate the T.AMBIENT function.
When this function is activated the appliance will automatically control the ON/OFF cycles according to the temperature set by the
user.
