When the desired water set pint of the machine has been reached, it will switch o displaying “H O ”.
If there are external thermostats connected to the machine, please consult the table on the next page.
WATER TEMPERATURE ADJUSTMENT
The appliance can control the water temperature through a digital probe which automatically adjusts the
machine functioning when nearing the desired temperature.
When the boiler has started and entered the normal functioning phase, display D1 will show the water 1.
temperature while display D2 will show the power set.
Adjust the desired water temperature using keys 2 and 3. During adjustment, “2. SET” in ashing mode and
the temperature to be set will appear on display D1 (the value has max travel from 60 to 80°C) whereas
the functioning power will appear on display D2.
When the desired temperature has been adjusted, let “3. SET” disappear from the display.
Adjust the desired functioning power using buttons 4 and 5. (N.B. the company recommends to set 4.
the boiler at maximum power to speed up the water heating process; the boiler will automatically slow
down when nearing the set temperature).
During normal functioning, display D1 will show “5. H2O AND THE REAL WATER TEMPERATURE” whilst
display D2 will show “FUNCTIONING POWER”. When the appliance reaches the set temperature, it will
automatically go to minimum functioning conditions.
THERMOSTATS CONNECTION
Winter Mode: INP 1 (T1) and INP2 (T2) have the same priority
* Winter DHW Mode (recommended for DHW managed by INP2): INP 2 (T2), has the priority over INP1
**Summer Mode: INP 1 is always ignored, paying attention only to INP 2 (T2)
The management of the external thermostat contact is considered in the board in he following way:
Key
ON= 230V, 50 Hz
OFF= 0 V
Heat request = contact closed in board
No heat request = contact open in board
Therefore when the board detects a closed contact, it interprets it as a request; when it detects an open
contact it interprets it as a non request. Therefore it is important to evaluate which type of external
thermostat to install.
