1.2.9 Test Mode

This function is used to bring the boiler to maximum power.
To start this operating mode, a heat request must be activated in heating or DHW mode.
When the central dot on the display starts flashing, keep the heating
more than 5 seconds.
The flashing number of the active heating elements will appear on the display (example with 3 active elements

1.2.10 External temperature compensation

If the external probe (optional) is installed and parameter P07 >0, the boiler control system works in "Sliding Temperature"
mode. In this mode, the heating system temperature is adjusted according to the weather conditions to ensure optimal
comfort and energy efficiency throughout the year. In particular, as the external temperature increases, the system flow
temperature decreases according to a specific "compensation curve".
With "Sliding Temperature", the temperature set using the heating buttons becomes the maximum system flow temperature.
It is advisable to set a maximum value to allow the system to be adjusted throughout its useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. However, the user can make additional
adjustments necessary to optimize comfort levels.
1.2.10.1 Compensation curve and curve offset
From the service menu (tS) it is possible to select the compensation curve (P07) and the offset (P06) according to the
system.
If the room temperature is lower than the desired value, it is advisable to set a higher curve and vice versa. Proceed by
single increases or decreases and check the result in the room.

1.2.11 Anti-legionella function

If the system is equipped with an external storage tank, the boiler performs the anti-legionella function by heating the tank
to the temperature set via parameter P12 (see 1.3.1 on page 10).
This function will be activated at intervals set via parameter P13 (see 1.3.1 on page 10).
During this function the display shows the symbol
