7.2.2 Setting the real-time clock in ZA
(only with Control Center 2 and 3)
When the system is in operational mode Ignition off (ZA) and the Temperature set point knob is turned
to the clock symbol (Figure 9), the weekday will be represented on the display with the digits 1
(Monday) to 7 (Sunday), interchanging (1.5 sec. / 1.5 sec.) with the time. The light-emitting diodes
(LED) in the key (hour key) and (minute key) blink. This means that these two keys can now
be used for defined operating functions (setting mode Weekday). By pressing the hour-key once
or repeatedly, the weekday can be set. If, after 10 seconds no further input is made, or if the
Temperature set point knob is rotated away from the symbol , then the setting mode Weekday will
be exited. The display will clear, and the LED’s in the keys and will no longer blink.
