Description

The Milesight WT303 is an advanced LoRaWAN fan coil thermostat for air-conditioning systems using 2-pipe or 4-pipe fan coil units (FCUs) with 3-speed or EC (0-10V) fans. It drives 2-wire or 3-wire On/Off motorized valves. It supports manual button control and automatic control via predefined logic, schedules or remote management for optimal comfort and energy efficiency.

A 2.7-inch e-ink display and a built-in temperature/humidity sensor continuously show room status, and it integrates with standard LoRaWAN gateways, BACnet (via Milesight gateways), Milesight D2D and the Development Platform for real-time monitoring and remote management.
