1.4.4 HOT WATER RAPID HEATING AND PRE - HEATING FUNCTION
Rapid heating
The rapid heating function can be used to quickly restore the suitable temperature in a cold environment: the boiler
will operate at maximum power for twenty-five minutes, in order to create the right conditions for a sudden rise in
temperatures in the installation.
At the end of this time interval, the boiler will go automatically back to the pre-set functioning.
To activate the rapid heating function, perform the following steps:
•
Activate the heating mode, by pressing the button
•
Press again & h o l d for three seconds:
the display will show a temperature of 40°C if the boiler is set on
the 'room temperature' mode; or 80°C if the boiler is set on the 'flow
temperature' mode.
To deactivate the rapid heating function:
•
Turn the dial.
Hot water pre-heating function
The pre-heating function consents to prepare the boiler for the provision of domestic hot water and to benefit of a
superior comfort: pre-heat function allows a faster delivery of hot water at the desired temperature shortening the time
needed for its production.
When the function is activated, the hot water preparing circuit is immediately raised to the right temperature and
mantained hot for thirty minutes (or until first use).
At the end of this time period (or after having used hot water), the boiler stops this function automatically in order to
reduce wasted energy and minimize the consumption, then returns to normal operation.
To activate the hot water pre-heating mode, follow the procedure:
•
