ECO/COMFORT selection
The unit has a function that ensures a high domestic
hot water delivery speed and maximum comfort for the
user. When the device is activated (COMFORT mode), the
water contained in the boiler remains hot, ensuring faster
availability of domestic hot water.
The device can be deactivated by the user (ECO mode)
by pressing the eco/comfort button (see item 7 on the
control panel display). To activate the COMFORT mode,
press the eco/comfort button (see item 7 on the control
panel display) again.
Outdoor temperature
• When the optional external probe is installed, the boiler
control system operates with “Sliding Temperature”.
In this mode, the temperature of the heating system is
controlled according to the outside weather conditions,
in order to ensure high comfort and energy saving
throughout the year. As the outside temperature
increases the system delivery temperature decreases
according to a specifi c “compensation curve”.
• With Outdoor Temperature adjustment, the temperature
set with the heating buttons (see items 3 and 4 on
the control panel display) becomes the maximum
system delivery temperature. It is advisable to set the
maximum value to allow system adjustment throughout
its useful working range.
• The boiler must be adjusted at the time of installation
by qualifi ed personnel. Adjustments can in any case be
made by the user to improve comfort.
