Digital multifunction timer with Bluetooth, 4-channel.Digital multifunction timer 4-channel with illuminated display, integrated Bluetooth function and app programming for time, brightness and location-dependent control.
Can be used as a day, week, year and astro clock, additionally with integrated twilight switch function. Exception control via wired external switch/button or KNX radio switch/button.
Programming on the device or via app: time and date (factory set), automatic summer/winter time change, public holiday and school holiday times can be selected depending on location, access blocked via app or key combination, temporary and permanent exception control on/off/pulse. Programs can be created in the app, adopted from previously used templates or exceptions can be activated. A portal can optionally be used to pass on and externally save the program. Bar display for quick recognition of the program.
Reduction of the contact load through zero-crossing switching. Programming without mains voltage possible via integrated power reserve (approx. 10 years).
Note: Communication protocol from version Bluetooth 4.2 and KNX radio RF quicklink. Twilight switch function via brightness installation or surface-mounted sensor is not included.
