Fig. 4.2 Display on ecoTEC plus
The ecoTEC plus appliance is fitted with a digital infor-
mation and analysis system. This system provides infor-
mation on the operating status of your appliance.
During normal operation, the display (
1 ) shows the cur-
rent heating flow temperature (in this example 45 °C). In
the event of a fault, an error code appears instead of the
temperature.
The display also gives the following information:
1 Indication of the current heating system flow
temperature or water pressure in the heating
system or display of a status or error code
Fan speed malfunction
Fan speed malfunction
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 (
9 )
and ( 10 ).
This condition can only be ended:
- using vrnetDIALOG or
- by a change in temperature at controllers (
9 )
or ( 10 ) of more than
±
5 K.
This condition cannot be ended:
- with the "Reset" button ( 8 ) or
- by turning the appliance off or on.
