1.3 Lighting and turning off
Boiler not electrically powered (fig. 5)
BThe frost protection system does not work
when the power and/or gas to the unit are
turned off. To avoid damage caused by
freezing during long idle periods in winter, it
is advisable to drain all water from the boiler,
DHW circuit and system; or drain just the
DHW circuit and add a suitable antifreeze to
the heating system.
fig. 5 - Boiler not electrically powered
Boiler lighting (fig. 6)
Switch on the power to the unit.
• For the following 120 seconds the display will show
FH which identifies the heating system air venting
cycle.
• During the first 5 seconds the display will also
show the PCB software version.
• Open the gas cock ahead of the boiler.
• When the message FH disappears, the boiler is
ready to operate automatically whenever domestic
hot water is drawn or in case of a room thermostat
demand. fig. 6 - Boiler lighting

ECO/COMFORT selection
The unit has a function that ensures a high domestic hot water delivery speed and maximum comfort for the user. When
the device is activated (COMFORT mode), the water contained in the boiler is kept hot, therefore ensuring rapid avail-
ability of hot water on opening the tap, without waiting times.
The device can be deactivated by the user (ECO mode) by pressing the eco/comfort button (detail 7 - fig. 1). To acti-
vate the COMFORT mode, press the eco/comfort button (detail 7 - fig. 1) again.
Outside Temperature Compensation (O.T.C)
When the optional external sensor is installed, the control panel display (detail 5 - fig. 1) shows the actual outside tem-
perature detected by the external sensor. In this mode, the heating system temperature is adjusted according to the
outside weather conditions, to ensure the high comfort and energy saving throughout the year. In particular, as the out-
side temperature increases, the system delivery temperature decreases according to a specific "compensation curve"
(fig. 12).
The maximum system delivery temperature can be set with the heating buttons (details 3 & 4 - fig. 1).
The boiler must be regulated at the time of installation by qualified personnel. Possible adjustments can in any case be
made by the user to improve comfort.
Compensation curve and curve offset (Only required if external sensor is installed)
Press the mode button (detail 10 - fig. 1) once to display the actual compensation curve value (fig. 12) which can be
modified with the DHW buttons (details 1 and 2 - fig. 1).
Adjust the required curve from 1 to 10 according to the characteristic (fig. 14).
By setting the curve to 0, sliding temperature adjustment is disabled.
It is recommended that a start point of 20 to 30°C and a flow temperature of 85°C is suitable for the UK (Curve
9 or 10).
fig. 12 - Compensation curve
Press the heating buttons (details 3 and 4 - fig. 1) to access parallel curve offset (fig. 13), modifiable with the DHW but-
tons (details 1 and 2 - fig. 1).
fig. 13 - Parallel curve offset
Press the mode button (detail 10 - fig. 1) again to exit the parallel curve adjustment mode.
If the room temperature is lower than the required value, it is advisable to set a higher order curve and vice versa. Pro-
ceed by increasing or decreasing in steps of one and check the result in the room (fig. 15).
