Item no.: 8120210

The RAMSES 812 top3 16A is a powerful digital clock thermostat in a slim, modern design for precise room temperature control. Designed for flush-mounted installation, it operates directly on the device or via smartphone app through Bluetooth Low Energy (BLE), without requiring internet access.

With an increased switching capacity of 16 A, it’s ideal for on/off heating systems, electric heating units, and zone-based or single-room control. Users can program 3 weekly schedules and choose from comfort, eco, or setback functions to optimize energy savings.

The thermostat also features an external input for connecting sensors or detectors, an illuminated display, and an intelligent control algorithm (pulse-width modulation, hysteresis control) for maximum efficiency. Low <0.2 W standby consumption and a 4-hour power reserve add to its reliability.

Smart, flexible, and efficient, the RAMSES 812 top3 16A is the perfect solution for modern heating management.
