Use the Touch Ring to enter the date in exactly the same way as for the holiday start date.
By default, the HOLIDAY mode start and end dates are set to the current date.
Make sure that the end date is after the start date – if not, the HOLIDAY mode will be disabled.
The final setting to be entered is the protection temperature
you want set while HOLIDAY mode is active.
Use the Touch Ring to set the preferred temperature and confirm
the choice using the OK button. Once the temperature setting is
confirmed, the HOLIDAY mode will be activated. While in this
mode the HOLIDAY mode indicator will be shown on the
display, but there will not be any MANUAL or AUTO indication.
