Overview
WT102 overview
Overview
The WT102 is a LoRaWAN smart radiator thermostat for managing heating control systems. It regulates room temperature automatically and manually, and reacts quickly to abnormal temperature differences or extreme cold by adjusting the valve opening.
Self-Powered, Maintenance-Free
Thermal energy harvesting powers the WT102 from the temperature difference of the heating circuit, eliminating battery replacement and wired power. When water temperature exceeds 45 °C, the device is powered via the thermoelectric effect.
Smart Heating Schedules
One preset date period with up to 16 customisable heating plans enables time-controlled regulation, automating comfort while reducing energy use.
Comfort & Safety
Open-window detection, freeze protection and a child-lock feature protect rooms and devices, while theft-deterring accessories add structural anti-theft protection for public areas.
Easy Setup & Linkage
NFC enables one-touch configuration, and the WT102 works with the WT401 wireless thermostat for remote linkage control. An external NTC sensor can be connected for accurate ambient sensing.
Integration
Compliant with standard LoRaWAN gateways and the Milesight Development Platform, with local storage of 1,000 entries, data retransmission and FUOTA for reliable operation.
