Eberle flush-mounted thermostat UTE 3500
- Electronic room thermostat for precise control of water-based heating systems
- Silent Triac switching output controls the heating actuators (note: for actuators with automatic hydraulic drive, UTE 3800 is recommended)
- Easy installation in 55x55 mm flush-mounted boxes
- Intuitive operation with dot matrix LED and touch buttons
- Adjustable control methods: PWM or two-point, heating and cooling
Precise temperature control for your home
The Eberle UTE 3500 is an electronic room thermostat specifically designed for controlling water-based heating systems. With its silent triac output, it can control up to five 3 W electrothermal actuators, enabling efficient and quiet control of your heating.
Seamless integration into your smart home
Thanks to support for the manufacturer-independent Matter WiFi standard, the UTE 3500 can be easily integrated into all common smart home systems. This allows control via popular smart home apps such as Google Home, Apple Home, or Amazon Alexa, without the need for additional hubs or special apps. Installation can also be performed without a WiFi connection, so the thermostat is ready to use immediately after selecting the heating application on the device.
Easy installation and versatile customization options
The thermostat is designed for installation in 55x55 mm flush-mounted boxes and thus fits into the most common switch frames from manufacturers such as Berker, Busch-Jaeger, Elso, Gira, Jung, and Merten. Operation is via a white dot-matrix LED display and touch buttons, ensuring intuitive handling. The UTE 3500 also offers adjustable control modes: You can choose between pulse width modulation (PWM) with a cycle time of 5 to 20 minutes and two-point control with adjustable hysteresis of 0.1 K or 0.5 K to optimally adapt the control to your needs.
Additional features for more comfort
The Eberle UTE 3500 features a frost protection function that prevents the room temperature from dropping below 5°C. A universal input allows it to be used as a setback or occupancy input, allowing the thermostat to respond flexibly to occupancy. Heating/cooling switching is also possible via an external input, facilitating use in systems with a cooling function.
