Upgrade to Smart, Precise Heating Control

error

Traditional radiators lack precise valve regulation, causing overheating and temperature swings.

right

The smart radiator thermostat offers more control over heating based on real-time temprature changes.

Surpassing traditional thermostats with fixed setpoints, Milesight Smart Radiator Thermostat WT10x delivers dynamic precision. By monitoring real-time room temperature, it automatically adjusts the valve opening to regulate the exact amount of hot water.

This smart mechanism ensures consistent comfort and superior energy efficiency.

Accurate Temperature Sensing

Built-in high-precision sensor enables accurate environmental detection for stable control.

Room-by-Room Control

Enable independent temperature
settings for specific zones or rooms.

Maximum Flow Regulation

Limit the maximum valve opening to control heat dissipation and avoid overheating.
