9 - START UP PROCEDURE
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. oor heating system).
When Low Temperature Thermostat connected on CN2 cuts out, burner switches o 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 specic 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).

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
