3.6 ELECTRONIC CARD SETTING
NOTE . The following operations must be carried out by
technicians authorised by the Manufacturer.
Unauthorised personnel shall not carry out any activities.
Wrong operations may jeopardise proper operation of the
boiler and render the guarantee certificate null and void.
The Manufacturer shall not shoulder any responsibilities
in case of equipment damage or damage caused to persons,
animals or objects by the equipment as a result of wrong
operations.
Before releasing the boiler to the final user, check the card
setting or set the card.
JUMPERS LIST
The METHANE/LPG jumper J7 (see figure below) selects
the modulation current field; disable for methane (gas
pressure calibration up to 12mbar); enable for L.P.G. (gas
pressure calibration up to 35mbar).
J19: DO NOT CHANGE THE POSITION SHOWN IN THE
FIGURE
J18: DO NOT CHANGE THE POSITION SHOWN IN THE
FIGURE
Jumper J17 enables the function which prevents frequent
starting during the heating stage; it is disabled on the
standard version. The above mentioned phenomenon
may occur if water circulates at low speed or when the
system is relatively small: if the function preventing
frequent starting is enabled, the boiler keeps the burner
off for at least 2.5 minutes, regardless of the water cooling
down, detected by the heating system probe.
Jumper J16 enables the parameter change mode: the display
blinks until it is enabled. Pacc and Pmax can be modified.
The start power Pacc can be adjusted by pressing the +/-
buttons only when the parameter change mode is enabled;
it is displayed as a % of the max. power: for methane 25
equals approx. 2.5 mbar, for L.P.G., 50 equals approx. 10.0
mbar.
Use a pressure gauge to check the gas pressure accuracy.
The Pmax heating power can be changed by pressing the
+/- buttons only when the parameter change mode is
enabled; it is displayed as a % of the max. power (it is pre-
set on 99, but this value must drop below 85 to start reducing
the max. pressure).
Use a pressure gauge to check the gas pressure accuracy.
