Item no.: 8119200

The RAMSES 811 top3 is a modern digital clock thermostat designed for time-dependent room temperature control in homes, apartments, and offices. Its flat design and flush-mounted installation make it discreet, while operation is possible directly on the device or via app using Bluetooth Low Energy (BLE), without the need for internet access.

It offers 3 programmable weekly schedules plus comfort, eco, and setback modes for energy-efficient heating management. Settings are configured easily through the app on a smartphone or tablet, providing intuitive and convenient control.

The thermostat includes an external input for connecting a room sensor, floor sensor, motion detector, or telephone contact, and features an intelligent control algorithm for accurate regulation. Powered by 2 AA batteries, it ensures flexible installation—even for retrofitting.

Compact, efficient, and user-friendly, the RAMSES 811 top3 is ideal for modern single-room or zone-based heating systems.
