9 - START UP PROCEDURE
9.15 Parameter Settings
Program boiler electronic board parameters as follows:
• Press
and
together, hold them down for 6
seconds until program “
P01
” appears on the display
alternated with the set value;
• Press
or
to scroll the list of parameters;
• Press
, value of selected parameter begins
flashing, press
to change the value;
• Press
to confirm the value or press
to exit
without saving.
Further information in regards to parameters listed in the
following table are supplied together with required accessories
if necessary.

P01
DHW Fast Modulation
00
=Standard Modulation - on DHW call for heat 10 seconds stabilization time before modulation
01
=Fast Modulation- on DHW call for heat 5 seconds stabilization time before modulation

Gas used
00
= Gas A (Natural Gas)
01
= Gas E (LPG Gas)

P03
Hydraulic system
00
= instantaneous appliance
03
= instantaneous appliance with pre-heat function
04
= heating only appliance with DHW thermostat
05
= appliance with external storage indirect tank
08
= heating only appliance

P06
Outdoor temperature sensor input configuration
00
= with outdoor temperature sensor connected, external temperature value has influence to calculate heating flow
temperature set-point
01
= with outdoor temperature sensor connected, display shows external temperature value (no influence)
02…05
= no function is associated

Parameters continued on next page
For Natural Gas :
Input (MBH)
=
3600 x cu ft
seconds
Example: Natural Gas - Gas flow from
Meter = 2 cu ft
Measured time = 72 seconds
=
3600 x 2 cu ft
= 100 MBH
72 seconds
For Propane (LP):
Input (MBH)
=
9160 x cu ft
seconds
For Metric formulas- See Glossary
2.
Compare measured input to table below. If calculated
input is not in range given in Table 9-2 check firing rate
again after setting the combustion following steps in
section 9.12.

P07
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).

P09
Hydraulic Component Setting
Default 01
P10
Heating set-point setting OT / RT (Open Therm / Room Thermostat 120V~)
00
= with Remote Control (RC) connected, temperature request is RC set-point
01
= Temperature Request is highest set point between RC and PCB
02
= Temperature request is RU setpoint. The RT enable the gas boiler operates
