10.3.5 Parameter Setting Menu
To set PCB parameters proceed as follows:
1.
Press
and
together for about 6 seconds, the
display shows "PO1" alternating with its value (01);
2.
The parameter setting menu is divided in pages, each with
10 parameters (ie Px0-Px9).
3.
: short push to go to the next page (e.g. from
P10-P19 page to P20-P19 page). See Note.
4.
: short push to go to the previous page (e.g. from
P20-P19 page to P10-P19 page). See Note.
5.
Address/Page Knob:
turning Left Knob permits scrolling
between the parameter within the current selected page.
See Note.
6.
If
Data Knob
(Right Knob) is moved, "NOP" is seen on
the display to inform the user that moving the Data Knob
has no consequences
NOP= N
o
OP
eration.
7.
short push: parameter visualized in display is selected
and the board goes in the Value setting menu.
8.
: short push to go to next page (e.g. from values 10-
19 page to 20-29 page)
9.
: short push to go to previous page (e.g. from values
20-29 page to 10-19 page)
10.
Data Knob: turning Right Knob permits scrolling the
values in the current selected page.
11.
: short push to save the value visualized on the
display and return to parameter setting menu.
12.
Address/Page Knob: returns to Parameter setting menu
without saving the current value (escape function).
This function always ends after 3 minutes, or sooner by
pressing
and
simultaneously with a long push.
Note
Knob design does not change scrolling
position when moving back and forth
between pages. If display was on
P07, a short push of
will result in
P17 display. Rotate knob to reach P11
through P16.
P70
Ignition fan speed setting: Fan Speed =
P70
* 100 rpm
P71
Maximum fan speed: Fan speed = 3500 +
P71
* 25 rpm
P72
Minimum fan speed: Fan speed = 750 +
P72
* 10rpm
Example
To set ignition speed at 3000 rpm
P70
= 30
To set max fan speed at 5800 rpm
P71
= 92
To set min fan speed at 1100 rpm
P72
= 35
Note:
Parameters in Grey are not visible unless
P22
is set at 22.

value helps to calculate the supply temperature setpoint
01= with an outdoor sensor connected, the display shows the outdoor
temperature value (no influence on supply temperature)

Aux input configuration
00..02 = No function is associated
03 = This is an input contact for CH request (e.g. trigger phone).
When contact CN2 is closed and Room Thermostat (RT) requiring
heat switches burner on.
Note: verify heating mode is enabled (winter or heat only mode)
04 = This is an input contact for Low Temperature Thermostat (e.g.
floor heating system).
When Low Temperature Thermostat connected on CN2 cuts out,
burner
switches off and display shows E178 anomaly.
Note: verify heating mode is enabled (winter or heat only mode)
05 = This is an input contact for external DHW recirculation pump.
When contact CN2 is closed the pump runs for a specific period.
To enable input it is necessary to set parameter P04 or P05 = 08 and
P69 = 05.
Pump will run at P19 minutes (Summer/Winter mode or Only Winter
mode) or P19/2 minutes (only Summer mode).
