The "Holiday" mode applies the "Frost Protection" temperature you have set in your settings for your main zone.
If you are in Multizone, the "Antifreeze" pilot wire order is applied in your secondary zones.
- "Until new order": is cancelled by clicking on "Cancel".
- "For a specific period of time": reverts to the current program/schedule set point at the selected date and time.
You cannot issue derogatory orders or apply any other mode, while "Holiday" mode is enabled.
