Checking of gas pressure values and adjustment with limited range
•
Check that the supply pressure complies with that indicated in the technical data table.
•
Connect a suitable pressure gauge to the pressure sampling point
“B”
located
downstream from the gas valve.
•
Activate the
TEST
mode and follow the instructions for checking the gas pressures
at maximum power and minimum power (see next par.).
If the maximum and/or minimum nominal pressures read on the pressure gauge are dif-
ferent from those indicated in the technical data table, proceed with the next sequence.
•
Press the Eco/Comfort button for 2 seconds to go to the gas valve Calibration with
limited range mode.
•
The card goes to the setting
“q02”
; displaying the currently saved value by pressing
the DHW buttons.
•
If the
maximum pressure
read on the pressure gauge is different from the nominal
one, proceed in increments/decrements of 1 or 2 units of the parameter
“q02”
by
pressing the DHW buttons: after each change, the value is stored; wait 10 seconds
for the pressure to stabilise.
•
Press the heating “-” button (ref. 3 - fig. 1).
•
The card goes to the setting
“q01”
; displaying the currently saved value by pressing
the DHW buttons.
•
If the
minimum pressure
read on the pressure gauge is different from the nominal
one, proceed in increments/decrements of 1 or 2 units of the parameter
“q01”
by
pressing the DHW buttons: after each change, the value is stored; wait 10 seconds
for the pressure to stabilise.
•
Recheck both settings by pressing the heating buttons and if necessary correct
them by repeating the procedure described above.
•
Pressing the Eco/Comfort button for 2 seconds returns to TEST mode.
•
Deactivate
TEST
mode (see next par.).
•
Disconnect the pressure gauge.
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).
