Greener and smarter controlling fan coil units in IoT Ways

Building energy simulation conducted showed that modulation control could save over 50% fan coil units (FCUs) fan energy compared with cycling on and off. The modulation control can also maintain a higher chilled water at part-load conditions, leading to over 50% savings in pump energy and more efficient chiller staging.

Starting here building energy retrofitting

The Milesight Smart Fan Coil Thermostat WT30x is an advanced touch screen room thermostat, offering access to parameters such as system mode, fan mode and temperature setpoints. Valves and auxiliary electric heaters can be controlled using a relay or contactor system switch controlled by the thermostat. It can be used in a variety of building applications, including hotels, schools and offices.

Wireless LoRaWAN® deployment

• easy deployment
  • The wireless communication takes advantage of the Long-Range characteristics of the LoRa physical layer, allowing a single-hop link between the end-device and one or many gateways
• higher security
  • LoRaWAN® ensures secure communication between the application server and the end device using AES-128 encryption

User-friendly and elegant product design

The WT30x comes in an all-white color and fits perfectly into different scenes. It features an LED matrix light for a simple, energy-efficient display. Digital display of ambient temperature, setpoint, mode icons when cooling or heating relays operate, when energy savings mode is active, and fan status.

Rotating based on accurate temperature sensing

By comparing the temperature setpoint with the current temperature, the WT30x enables both proactive management and automatic control based on predefined logic.

• the fan can be controlled from the thermostat, which offers three fan speeds (low, med, high) and auto
• with built-in temperature sensor, WT30x enables environmental detection and accurate control
• NTC port allows connection of additional temperature sensors for more precise monitoring
• supports wireless connection of external temperature sensors via LoRaWAN® gateway

Strong connectivity

By incorporating Milesight LoRaWAN® gateways and harnessing the power of platforms using various communication protocols that encompasses MQTT(s), HTTP, and BACnet, the WT30x brings advanced performance to energy-efficient management, remote control, and data-driven management optimizations.

Smarter temperature management

• With factory default and customized settings, users can adjust the thermostat to their actual needs while enjoying precise and stable management.
• clock display with 12-hour system or 24-hour system
• support temperature compensation factory default
• secured data memory when power is off
• button lock functions to avoid tampering

LoRaWAN® based

• penetrating signals: data transmission range up to 2 km in urban areas and 15 km in rural areas
• high compatibility: compliant with standard LoRaWAN® gateways and network servers
