TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 1) together for 5 seconds to activate the
TEST mode. The boiler lights at the maximum heating power set as described in the fol-
lowing section.
The heating and DHW symbols (fig. 19) flash on the display; the heating power will ap-
pear alongside.
fig. 19 - TEST mode (heating power = 100%)
Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power
(Min.=0%, Max.=100%).
By pressing the DHW "-" button (detail 1 - fig. 1), boiler output is immediately adjusted
to min. (0%). By pressing the DHW "+" button (detail 2 - fig. 1), boiler output is immedi-
ately adjusted to max. (100%).
If the TEST mode is activated and enough hot water is drawn to activate the DHW mode,
the boiler remains in TEST mode but the 3-way valve goes to DHW.
To deactivate the TEST mode, press the heating buttons (details 3 and 4 - fig. 1) together
for 5 seconds.
The TEST mode is automatically deactivated in any case after 15 minutes or on stopping
of hot water drawing (if enough hot water has been drawn to activate the DHW mode).
Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 4.1). Press the
heating buttons (detail 3 - fig. 1) to increase or decrease the power (min. = 00 - max. =
100). Press the reset button within 5 seconds and the max. power will remain that just
set. Exit TEST mode (see sec. 4.1).
Configuration Menu
The configuration Menu is accessed by pressing the DHW buttons together for 10 sec-
onds. 12 parameters, indicated by the letter "b" and not modifiable from Remote Timer
Control, are available.
Press the Heating buttons to scroll the list of parameters in increasing or decreasing or-
der. Press the DHW buttons to view or modify the value of a parameter: the change will
be automatically saved.
