Theben Bluetooth OBELISK top3 Memory Card

The Theben OBELISK top3 is a dedicated BLE (Bluetooth Low-Energy) dongle designed to facilitate secure, wireless programming of compatible time switches via mobile devices. When plugged into the time-switch interface, this compact adapter enables the transfer of scheduling programs and direct commands from Theben’s app, ensuring high-security manipulation control and efficient configuration in lighting automation, building control, and commercial installations.

Crucial Features and Benefits of the Theben Bluetooth Low-energy Dongle

• Enables wireless programming via Bluetooth from a smartphone or tablet.
• Incorporated memory card (EEPROM) stores up to 56 schedule/program locations.
• Plug-in dongle only allows programming when installed, prevents unauthorised changes.
• Very low standby power consumption, ideal for always-on control systems.
• Compatible with Theben’s top2 and top3 series timers, enabling backward compatibility.

Secure, Efficient Programming for Modern Time-Switch Systems

The OBELISK top3 dongle empowers facility managers and installers to program time switches without physical intervention in locked enclosures or control cabinets. The built-in memory card ensures that programming only works when the dongle is present, adding a layer of security in environments where schedule integrity is critical (for lighting, HVAC or equipment control). Moreover, the low-energy design means the dongle can remain connected without adding unnecessary electrical load or maintenance overhead.

Versatility in Applications

• Wireless programming of time-switch schedules in commercial lighting systems.
• Set up and configure building automation timers and HVAC control devices.
• Retrofitting existing Theben top-series timers with a modern BLE interface.
• Site commissioning and field maintenance.
• Secure schedule updates in multi-tenant buildings.
• Integration into smart-building workflows for lighting, shading, and energy management.
