Last question: When will UCM/Cbus participate in the Time Master negotiation (if selected) and broadcast time at regular intervals to Cbus?
EG. Selectable 30 to 150 minutes to comply with other Time Master devices on Cbus. The challenge is to ONLY allow time updates of 150m if there is no Eth03 configured for NTP. From the Cbus standards this then does not qualify for anything better (or higher priority) and something like a PAC or Touch screen takes preference. Perhaps tag the Date/Time update from the Eth03 if it\'s set by NTP, ignore all others. Maybe even give the DT command a tag so that CC could also be considered \'trusted\' if the user has a PC in sync using NTP and also updates Comfort via the UCM/Ethernet if no Eth03 is used.

UCM/Cbus takes part in Time master based on fixed long wait time of 70 minutes
There is no selection of wait times at the moment.

Thanks Chiu, it seems we are still waiting on that \'future development\' mentioned in earlier posts. To wrap-up, Comfort does not become a Time Master to Cbus if you have another \'same priority\' device EG. PAC. even though Comfort with NTP is more accurate.
