Please be advised that Designer Series products (models IT, IC, ID, IW) that have the Smart Grid Option enabled for connection to either the Sub-Zero Group Owner’s App or third-party home system do not return to Sabbath Mode after a power outage.

Please refer to the manufacturer’s recommendations at the Sub-Zero website, which notes:

• To prevent this, the Smart Grid Option must be disabled.
• Disabling the Smart Grid Option prevents the unit from being connected to the Sub-Zero Group Owner’s App or third-party home system.
• A Wi-Fi icon or home and power cord icon appears when the unit has the Smart Grid Option enabled.
• The unit does not have to be paired to the Sub-Zero Group Owner’s App or a third-party home system for this issue to occur. The Smart Grid Option must be disabled regardless of connected status.

This issue has been resolved in newer models but affects owners of older models. Please refer to the chart below to help identify the affected models:
