2 Time
3 Active operating mode
The illumination of the display is switched on by pressing any
button or using the input button
if no buttons are pressed for a longer period of time.
During start-up of the unit and after a power failure, a segment
test with automatic fault diagnosis is carried out. The respective
device type and the software version number then appear briefly.
The basic display that then appears shows the day of the week,
the date, the time and the heat generator temperature in
automatic mode. Different values appear in the basic display
depending on the set operating mode (AUTOMATIC, PARTY
etc.). Thus, for example, in the ABSENT operating mode, the
indication ABSENT TIL appears instead of the date and the return
date instead of the temperature. Active summer deactivation is
indicated by a beach umbrella symbol
protection is indicated by a snowflake symbol
