    Can I please get clarification about the daylight savings setting tickbox from the wiser control web page and the daylight savings found in the project options tab through PICED.

    Are they the same thing? I have noticed that when I change the project options it changes the sunrise / sunset settings on the wiser to be +1 hr. But when I change it on the web front end it changes the time on the wiser.

    It is driving me crazy. If I do not turn any of these things on, the scheduler works as expected on time etc.

    When I turn on daylight savings, everything gets stuffed up. Schedule event times are off by an hour. Sunset / sunrise schedules are just totally out of whack, it will close my blinds at 18:20 instead of 16:10 or 17:10. I have no idea where it gets this time from. Because I have scheduled for it be closed at sunset. It is soooo frustrating :mad:

    I am running PICED 4.12.1 wiser 1.0.28

    I have set my blinds to close at sunset. The time the wiser calculates this is 18:10, with daylight savings 19:10. Instead it closes now about 18:20.

    I have tried everything, including resetting all the RBCPs deleting and recreating on the schedules. It is driving me nuts.

    The "Enable Daylight" checkbox in the Adobe Flash UI for the Wiser UI turns on/off daylight savings. Meaning it turns on/off DST in C-Bus and thus the time shown will be changed. In contrast, in PICED->Project->Project Details, the Daylight Savings tab is just to specify whether or not there is any daylight savings (ie: checking the Add 1 hour option tells the Wiser that it should turn on/off daylight savings) when the date prescribed in the schedule is hit. It will not affect the system at all. Only when that project is on the Wiser, and there is an actual transition to that date, will it change DST. To put it another way, if you upload a project to your unit after daylight savings has started, and your C-Bus network does not have DST set (eg: within the Wiser CNI), then DST will not be set. If your C-Bus network has its DST set, then the Wiser will preserve that and DST will be set.

    Hi,

    Normally, if you have a CTouch, a PAC, or a Wiser, there should be a Daylight Savings schedule in ONE unit on your network. If you have Colour CTouch, the operating system handles the schedule (and you should NOT have a schedule in any PAC/Wiser/CTouch on the network).

    This schedule knows when Daylight Savings starts and ends, and automatically adjusts the system time accordingly. In the project options, you are selecting whether to include a Daylight Savings schedule in that project. It's important to only do this in one device.

    The tick box in the Wiser UI (or CTouch) is to manually do the same thing as the schedule.... you should never have to touch this if your DST schedule is set up and running properly.... but if the time/DST state is wrong, this option is there to correct it manually.

    The Sunrise and Sunset times are calculated based on your location (set in the project properties)... this has to be adjusted for DST.

    Once you get your location, DST schedule, DST state, and Time all correct, your sunrise/sunset schedule should work.

    The only thing that still puzzles me is that you say the unit tells you that sunset is at 10 past the hour but the even is occurring at 20 past... the only thing I can think of is that there is the factility to add an offset to the sunrise/sunset time in the schedule.. so check you have nothing set there.

    Hope this clears things up.

    Nick
