9.14 Description of Parameters: Factory Settings conti.
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
P06
(no influence)
02...05 = no function is associated
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
P07
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
Manufacturer information
Heating set-point setting OT / RT (Open Therm / Room Thermostat 120V~)
00 = with Remote Control (RC) connected, temperature request is RC set-point
P10
01 = Temperature Request is highest set point between RC and PCB
02 = Temperature request is RU set-point. The RT enable the gas boiler operates

P23
Maximum DHW set-point temperature 113°-140°F (45°-60°C), Default 49 = 120°F
P24
Manufacturer information
P25
No water safety device
P26..P31 Manufacturer information
P32..P41 Diagnostics (See SERVICE Instructions)
Temperature unit setting
00 = °C
P44
01 = °F
P71 * P
Maximum fan speed
P72 *
Minimum fan speed
NOTE :
To scroll to parameter P71 and P72 it is necessary to set P22 to 22 before scrolling up to the parameter.
* See Tables : SECTION 12.2 - Parameters Setting For High Altitude.
