Issue
The MPM controller does not adjust the clock automatically when Daylight Saving Time (DST) period occurs.
Product Line
EcoStruxure Building Expert
Environment
SmartStruxureLite Multi-Purpose Manage
Cause
DST settings in the MPM are configured for North America.
- Canada and United States: Daylight saving time begins on the second Sunday of March and ends on the first Sunday of November
- Europe: Daylight saving time begins on the last Sunday of March and ends on the last Sunday of October
Resolution
In Firmware 2.15, DST properties can be configured in the Controller Configuration Object (CFG1) and/or configuration page. DST start and end configuration on month, week, weekday, hour and offset can be set.
If using a firmware version older than 2.15, a script can be used to correct the issue. The script can be found here: Daylight_Saving_Time_DSC.lua
