Two types of weekly schedules are available in EU-M-9t controller:
1. Local schedule
It is a weekly schedule assigned to a particular zone. Once the controller detects the room sensor, the schedule is assigned
automatically to the zone. It may be edited by the user.
2. Global schedule (Schedule 1-5)
Global schedule may be assigned to any number of zones. The changes introduced in the global schedule apply to all zones
where the global schedule has been activated.

15
After selecting the schedule select OK and move on to edit the weekly schedule settings:
Screenshot showing the screen for editing the settings of the weekly schedule
Editing enables the user to define two programs and select days when the programs will be active (e.g. from Monday to
