Thanks to its particularly long range, the dnt LoRaWAN radiator thermostat eTRV is an excellent choice for automated room climate control in public and spacious buildings such as educational institutions, industrial plants, public authorities, hotels or office complexes. The minimalist design makes the radiator thermostat unobtrusive, while the anti-theft device and lockable battery compartment protect the device against tampering and disassembly.

It is ideal for room climate control, preventing manipulation and theft, saving energy, and provides high range. It also features open window detection and configuration options.
The thermostat has a closed housing without manual controls, a lockable battery compartment, and a theft protection mechanism to prevent removal from the valve.
It has a low power design, automatically lowers the temperature when open windows or doors are detected, and offers various configuration options via LoRaWAN-Downlink.
It's compatible with M30x1.5, RA, RAV, and RAVL valves. Adapters are available.
The package includes the dnt-LW-eTRV, instruction manual, valve adapters, 2x AA batteries, and a square wrench.
The typical LoRaWAN range is greater than 6km in open field conditions (SF9, Gateway: Kerlink PDTIOT-ISS04).
Yes, you can store 3 weekly profiles with up to 10 changes per day. A manual positioning mode also allows direct valve positioning for custom heating algorithms.
The thermostat lowers the room temperature to a defined level when open windows are detected.
It features dynamic adaptive adjustment (automatic radiator balancing), frost protection (automatic heating below 4°C), and a vacation mode for temperature adjustments during a defined period.
The device monitors the battery voltage and sends a notification when it's low. It also positions the valve before complete battery failure.
The main applications are remote and precise temperature control using time-controlled profiles. Each profile can have up to 10 points per day.
It features easy mounting with an M30x1.5mm connection thread and includes Danfoss adapters. It also automatically decalcifies the valve monthly.
It offers theft and tamper protection, including dismantling protection, a lockable battery compartment, and a tamper alarm that is triggered on unauthorized opening.
It supports manual temperature, manual positioning, auto, holiday, window-open, boost, frost, and emergency operating modes. It also supports firmware updates.
The battery life is typically less than 5 years and varies depending on usage.
It supports Class A.
It supports Heimeier, MNG, Junkers, Honeywell-Braukmann, and Oventrop valves directly (M30x1.5mm connection). Danfoss RA, RAV, and RAVL adapters are included.
The tamper contact function triggers an alarm via LoRaWAN® Uplink if unauthorized opening is detected.
Yes, it uses an adaptive PI controller that is configurable.
Time synchronization can be automatic via LoRaWAN® UTC or done manually.
