Milesight WT101 - WT102 Smart Radiator Thermostat

The WT10x smart radiator thermostat enables direct control of heating thanks to accurate temperature measurement. Available in the battery-powered WT101 variant or the self-powered WT102 variant, it ensures maximum energy efficiency and significant cost savings.

The Milesight Smart Radiator Thermostat WT10x overwhelms traditional thermostats with fixed settings and offers dynamic precision. By monitoring the room temperature in real-time, it automatically adjusts the valve opening to regulate the exact amount of hot water. This smart mechanism ensures constant comfort and superior energy efficiency.

Accurate temperature measurement

The built-in, highly accurate sensor provides precise environmental measurement and thus ensures stable control.

Control per room

Set independent temperature settings for specific zones or rooms.

Control of maximum flow

Limit the maximum valve opening to regulate heat output and prevent overheating.

Optimise your heating, minimise your effort

Zero-waste strategies

Smart scheduling

Supports up to 16 customised heating schedules within a pre-set period.

Automatically adjusts temperatures to specific daily routines, achieving precise comfort and minimising energy consumption.

Open window detection

Automatic frost protection
