Your ViCare heating schedules run according to the time on your boiler / heating device. Please check on the HMI of your heating device that this time is correct and not running late, behind or has not been updated according to a change in Daylight Savings (Summer/Winter times).
If you couldn't find the answer, you have several options:
- You can try to ask via customer-care@viessmann.com
- Contact your installer.
