As long as this symbol appears in the display, a
heating flow temperature and hot water outlet
temperature is set by the vrnetDIALOG accesso-
ry, which means the appliance uses temperatu-
res other than those set using the controls (10)
and (11).
This condition can only be ended:
- using vrnetDIALOG or
- by a change in temperature at controllers (10)
or (11) of more than 5 K.
This condition cannot be ended:
- with the "Reset" button (9) or
- by turning the appliance off or on.
