To open the front panel, grip the recess and fold the

ing functions (cp. Fig. 4.1):
1 Display indicating the current heating flow tem-
perature, the filling pressure of the heating sys-
tem, the operating mode and other additional in-
formation
2 Button "i" for calling up information
3 Controller (accessory)
4 Button for switching the unit on and off.
5 "+" button for navigating forwards through the
display view (used by expert technician to speci-
fy settings and for troubleshooting) or for dis-
playing the cylinder temperature (with cylinder
sensor)
6 "–" button for navigating backwards through the
display view (used by expert technician to speci-
fy settings and for troubleshooting) and for dis-
playing the filling pressure of the heating system
7 "Reset" button for resetting the system in the
case of specific faults
8 Rotary knob for setting the heating flow temper-
ature. When using with the VRC 430, 630 and
VRS 620, set to the clockwise end stop so that
the maximum flow temperature for the controller
will not be limited.

9 Rotary knob for setting the storage tank temper-
ature (on units with the VIH domestic hot water
cylinder connected ). When using the VRC 430
for controlling the cylinder temperature, set the
knob to the clockwise end stop so that the work-

Fig. 4.2 ecoCRAFT display
ecoCRAFT units are equipped with a Digital Information
and Analysis System. This system provides information
on the operating status of your appliance and helps you
deal with problems.
During normal operation, the display (1) shows the cur-
rent heating flow temperature (in this example 49 °C). If
a fault develops, an error code appears instead of the
temperature. In addition, your ecoCRAFT has a plain
text display which is used for displaying supplementary
information.

Only in combination with the vrnetDIALOG:
As long as this symbol appears in the display, the
heating flow temperature and hot water outlet
temperature are specified by vrnetDIALOG (ac-
cessory), which means the unit operates at tem-
peratures other than those set using the rotary
knobs (8) and (9).
