If the TEST mode is active and there is a DHW demand (by drawing hot water), the boiler remains in TEST mode but
the 3-way valve goes to DHW.
To deactivate the TEST mode, simultaneously press the heating buttons (details 3 and 4 - fig. 1) for 5 seconds.
The TEST mode is automatically disabled in any case after 15 minutes or by not drawing hot water (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. 3.1). 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. 3.1).
