41Operating manual for the auroMATIC 620 0020094404_00 Controller
5.14 Service functions (only for the expert
technician)
i
The service functions are reserved for the
expert technician and the district chimney
sweep.
The maximum output function is necessary for emissi-
ons measurement and manual operation is needed for
functional testing of the system.
If you activate the service functions unintentionally, you
can terminate them by simultaneously pressing both
and
knobs as often as necessary until the display
shows the basic view again.
5.15 Ensuring protection from frost
b
Caution!
Material damage caused by frost!
If you do not ensure adequate protection
from frost for your heating installation during
your absence, damage to the building and the
heating installation can result.
Make sure that adequate frost protection
is guaranteed during your absence.
Your controller is equipped with a frost protection func-
tion (depends on the outside temperature). The frost
protection function ensures that your heating installa-
tion is protected from frost in the Off and Eco (outside
the time windows) modes.
If the Eco mode is set and the frost protection function
(dependent on the outside temperature) is not activa-
ted, then the heating circuit will be switched off during
the set-back period.
The preset (night) set back temperature is applied auto-
matically for each heating circuit if the outside tempera-
ture falls below +3 °C (¬ Chap. 5.8).
Here's how to guarantee protection from frost:
Check that your boiler is connected to the electrical
mains. The boiler must not be disconnected from the
mains.
Check the mode set on the controller. Frost protec-
tion is only ensured in the Off and Eco modes.

5.16 Cleaning and caring for the controller
Use only a damp cloth to clean the casing of the con-
troller.
Do not use scouring or cleaning agents which could
damage the operating elements or the display.
5.17 Data transfer
Data transfer only takes place if your heating installa-
tion is fitted with the VRC DCF external sensor
(¬ Table 1.1, Part No.).
Depending on the conditions on site, it can take up to
15 minutes for all the data (outside temperature, DCF,
appliance status etc.) to be updated.
