for the user
If an external probe has been installed (optional Hermann kit), heating system temperature is
automatically controlled by boiler depending on external temperature. Pressing knobs
and
can vary a “dispersion coefficient” (please refer to technical documentation included with said kit).
PLUS FUNCTION
Inserting PLUS function EURA produces hot water
in an extremely short time giving same comfort as
boiler with a big DHW tank.
To switch PLUS function on (off) it sufficient to press
knob, both in summer and winter mode. When
plus option is on, the writing ‘plus’ is displayed.
REGULATING ROOM TEMPERATURE
We want here to remind you that the room temperature must be regulated through a room
thermostat with two temperature levels. This required by law XXXX [Italian reference: DPR
26 Agosto 1993 n°412 and relevant changes].
Please always refer to instruction manual enclosed to room thermostat.
BOILER FILLING
It is not necessary by end user to check water pressure inside boiler since EURA is provided with
a special automatic filling device.
In case of anomaly, a special alarm will be displayed. Please refer to paragraph ‘Boiler blocking and
alarm codes’.
ANTI FREEZING PROTECTION
Eura is equipped with an Anti freezing device, which keeps temperature in heating and domestic
system above 5 °C. Such system is enabled also when boiler is ‘OFF’ (green light flashing), provided
that boiler is fed by gas and electricity.
In case of gas or electricity failure, boiler can’t turn on and antifreeze protection is performed by
pump only, keeping water flowing.
It is important to underline that said anti freezing protection is a preventing device. It is not
recommendable to leave boiler unused for long periods where climate is very cold. In this cases
please contact a technical centre for either draining all system or inserting an anti freezing solution.
