WT30x is a LoRaWAN® smart fan coil thermostat compatible with 2-pipe and 4-pipe FCUs. A perfect fit for commercial HVAC systems, it supports efficient FCU retrofits and enables centralized climate management with measurable energy savings.

WT303/WT304 is the next iteration of WT301/WT302, extending compatibility to 4-pipe FCUs, EC fans, and more complex scheduling needs. WT303&WT304is an advanced room thermostat specifically developed to oversee fan and valve operations in air conditioner applications where 2-pipe or 4-pipe fan coil unit (FCU) with 3-speed fan or ECM fan is adopted. It allows manual control by buttons, and automatic control through predefined logic, scheduled programming or remote management system. This ensures optimal comfort and energy efficiency in the controlled environment. With 2.7’ e-ink screen and embedded temperature and humidity sensor, the thermostat continuously displays the room status while monitoring the ambient temperature and humidity. It is compatible with standard LoRaWAN® gateway and Milesight Development Platform, enabling real-time monitoring of environmental status for effective remote management.
