For its timer functions, the QAW740 room unit requires the time from the time
master. It can receive the time over the KNX bus subject to the following criteria:
• A bus device must be defined as the time master (setting "Clock time op:
Master").
• The QAW740 room unit is connected to an RM... controller via a "Geogr zone
(apartm)". For communication and filtering purposes (see section 8.2) the time
master and the room unit should preferably be in the same "Geogr zone
(apartm)". However, this is not mandatory.
• The room unit must have received the time from the time master. Note: The time
master transmits the time only every 10 minutes.
