can you use a pac to display the time on a dlt
There is an option when you set up the DLT to show the clock. You don't need a PAC to *show* to the clock. You can turn this on and use the DLT to set the time (its a bit obscure, I'm not sure where the instructions are published to do that, but it can be done). The DLT will lose the time if the power fails, though. In order to get a source of the time that is maintained and up-to-date, you need some other device containing a battery backed real-time clock that can act as a date and time master device. There are number of devices can do this: PAC, B&W C-Touch, Colour C-touch, C-Gate / schedule Plus, HomeGate. The PAC is not really a good device to use for this time mastering function because it does not have its own user interface, so initial setup and changes to the time can be quite painful.
Page 9 of the DLT User Guide explains how to set the time on a DLT. Just hold down the bottom button for 10 seconds and follow the prompts. Setting the time on the DLT will result in the time being broadcast and all other devices on the network including DLT's, if the clock is enabled, will update to the new time. DLT's, by default, just hide their clock if the time is not set. If you don't want to have to manually set the time each time there's a power failure or you want the clocks to automatically update for daylight saving then you'll need one of the devices Ashleigh mentioned and program them accordingly.
