9.16 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
P06
01= with outdoor temperature sensor connected, display shows external temperature value (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 display shows
P07
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 setpoint. The RT enable the gas boiler operates
