■ Set the required parameters during
commissioning; see from page 83.
■ Connections, see separate "Connec-
tion and wiring diagram" sheet 40 to
sheet 192
Note
■ Plug F11: Nothing should be connec-
ted to plug F11 on site.
■ Flow temperature sensor for heat-
ing circuit with mixer (M3): The flow
temperature sensor for one heating
circuit with mixer (M3/HC3) is connec-
ted to the mixer extension kit (acces-
sories).
