LoRaWan Smart Thermostat for Fan Coils WT304

LoRaWan Smart Thermostat for Fan Coils WT304

The WT304 is a LoRaWAN smart thermostat designed for 2 or 4-pipe fan coil units (FCU) with 3-speed fan . Thanks to its 0-10V analog output, it allows precise control of modulating valves, ensuring optimal comfort and intelligent energy management of commercial, hotel or industrial buildings.

A professional thermostat for fine regulation of heating and air conditioning

The WT304 thermostat is designed to meet the requirements of modern buildings. It is capable of controlling proportional valves (0-10V) and automatically regulating the temperature according to the setpoint and ambient conditions. The 0-10V voltage is dynamically adjusted to open the valve more or less depending on heating or cooling needs.

Unlike on-off relay thermostats (type WT303), the WT304 offers continuous control of the power transmitted by the valve, which improves comfort and reduces thermal surges. This modulation also optimizes energy consumption by maintaining a more stable temperature, without overheating or waste.

With its clear user interface, wireless connectivity and advanced features, the WT304 becomes an essential building block for any BMS (Building Management System) or HVAC system modernization project.

A clear and modern display

The WT304 is equipped with a high-contrast 2.7-inch e-ink display , perfectly readable even in broad daylight. It displays the current temperature, humidity, setpoint, as well as operating modes (heating, cooling, ventilation, etc.). The user interface is completed by 5 physical buttons allowing local manual control (On/Off, modes, temperature adjustment, etc.).

LoRaWAN connectivity for remote control

The thermostat communicates via LoRaWAN® , making it compatible with most industrial LoRaWAN gateways and platforms like Milesight IoT Cloud . It can be integrated with BACnet monitoring solutions via Milesight gateways, or with building management systems (BMS).

It also supports Milesight D2D , a local, gateway-free protocol ideal for installations where instant responsiveness is required.

Advanced features for intelligent regulation

The WT304 doesn't just regulate temperature. It offers advanced features such as:

• Smart scheduling : up to 8 programs with 16 time slots each

• Frost protection and window opening detection

• Child lock to secure the interface

• Automatic dehumidification and ventilation mode

• Input for external NTC sensor or dry contact (badge, switch, etc.)

• Remote updates via FUOTA (firmware over-the-air)

• Agent mode or D2D controller for ultra-fast local control

• Receiving data from external LoRa sensors

Thanks to these options, it adapts to multiple scenarios: hotel, open space, school, logistics site, etc.

Easy installation and wide compatibility

With a 100~240V power supply, the WT304 is easily installed on standard wall boxes (60 mm round, 86 mm square or 118/120 mm boxes with plate). Its compatibility with different box sizes makes it a versatile choice for renovation or new installations.

Its discreet white casing made of flame-retardant PC+ABS plastic (UL94 V0) fits easily into any professional environment.

Typical applications

The WT304 is particularly suitable for:

• Hotels and tourist residences

• Offices and meeting rooms

• Healthcare establishments or retirement homes

• Classrooms, schools, universities

• Shopping centers or tertiary premises

• Industrial sites with thermal comfort requirements

In summary

The WT304 thermostat is a smart, connected and high-performance solution for fine-tuning fan coils via 0-10V valves . Thanks to its LoRaWAN connectivity, its readable e-ink screen, its advanced features and its possible integration into a BMS or an IoT system, it offers an excellent compromise between user comfort , energy optimization and ease of installation .
