Why does the ZEB sometimes charge at peak times (when on any of the charging styles)?
Learn how Smart, Basic, and Custom Charging modes affect heating and peak-time charging
If you are on ‘Smart’ or ‘Basic Charging’, on cold days the ZEB will perform a full charge. It may also require a top-up charge during peak times to ensure you have enough heat for the entire day.
If you are on ‘Custom Charging’, you control when the ZEB charges. If you notice unexpected charging during peak times, you should review your Custom Charging schedule.
