1.4.4 Tank temperature adjustment

This function is available only with p05 = 1
Use the buttons (details 5 and 6 of fig. 1 on page 6) to adjust the temperature of the water tank.
The range of the setting is 30 - 60 °C and the default value is 60 °C.
To disable the DHW function, modify the set point below the minimum, till the symbol

1.4.5 Central Heating modulation

At every heating start-up the elements are activated one by one to reach the target temperature.
The minimum timing between each activation is 10 seconds, and the sequence start from the element that has accumu-
lated less working hours.
1.4.5.1 Comfort / Balance mode (P10)
Using the Parameter P10 it is possible to select the switch off mode during central heating function.
P10 = 0 Comfort
The heating elements stop working under the condition
- CH water temperare > CH Set Point + 5°C.
Then the heating elements start working again when the temperature is below the CH Set point - P02 and a timeout of 3
minutes are elapsed, to prevent frequent ignition.
P10 = 1 Balance
The heating elements stop working under the following conditions
- CH water temperare > CH Set Point + 5°C.
- CH water temperature > CH Set Point + 2°C. for 5 minutes
Then the heating elements start working again when the temperature is below the CH Set point - P02 and a timeout of 3
minutes are elapsed, to prevent frequent ignition.

1.4.6 Frost protection function

This boiler is equipped with different kind of frost protection, depending of the temperature.
1.4.6.1 Level I freeze protection
In case of the central heating temperature is <=8 °C, the water pump will run all the time and it will stop and exit from frost
protection when the heating temperature >10 °C. During this level, the display shows "Fd".
1.4.6.2 Level II freeze protection
In case the central heating tempearture decreases till =<5 °C, also the heating elements start to operateand the display
shows the heating temperature.
The condition to switch off the heating elements is when the temperature reaches the 30 °C, then the pump continue to
run for the post circulation time (parameter P01).
1.4.6.3 External tank frost protection (P05 = 1)
When the DHW temperature is detected to be lower than 5 °C, the three-way valve output will automatically switch to
water tank and start heating. When the water tank temperature exceeds 20 °C, the frost protection function stops. If the
water tank temperature sensor fault is detected, the machine won't enable the tank frost protection function. Note: The
water pump shall operate all the when this function is active.

1.4.7 Operating the water pump based on anti-sticking function:

If the time since last water pump operation exceeds 21 h, the water pump will operate for 30 seconds.
In case the tank function is enabled the three way valve moves in tank position the last 10 seconds.

1.4.8 Test mode

This function is used to put the boiler at maximum power.
To start this operating mode it is required to activate an heat demand , central heating or tank mode.
When the central dot on the display starts to flash, press the "+" and "-" CH button at same time for more than 5 sec, then
the test mode start.
On the display wil be visualized the number of active heating elements flashing.
