WT401 — Flexible HVAC Control Without the Limitations of Traditional Wiring

Milesight WT401 is a smart LoRaWAN thermostat designed to control heating, cooling, and ventilation in modern HVAC systems.

The wireless design allows the thermostat to be positioned in the optimal location in the room, regardless of existing wiring. Built-in temperature, humidity, and PIR occupancy sensors provide the data needed to automatically maintain comfortable conditions and reduce unnecessary energy consumption.

Comfort, Automation and Flexible Installation

Wireless Installation

Battery power and LoRaWAN communication allow the thermostat to be installed without running new communication wiring.

PIR up to 6 m

The built-in occupancy sensor allows HVAC operation to be adapted to actual room use.

8 operating plans

Local schedules enable automatic temperature adjustment according to the time of day, usage pattern, and facility requirements.

Where Can the WT401 Be Used?

Offices
Hotels
Retail Stores
Apartments and Flats
Commercial Buildings
Smart Building
HVAC Retrofit
Centralised Heating and Cooling Management

Compatibility with Different Heating and Cooling Systems

The WT401 can work with HVAC systems via LoRaWAN and a supervisory system or compatible Milesight HVAC controllers.

The manufacturer provides for use of the thermostat with PTAC systems, boilers, furnaces, heat pumps, and radiators working with Milesight WT101 or WT102 thermostats, among others.

Occupancy information can be used to automatically change the HVAC control strategy. This helps reduce heating or cooling in unused rooms.

2,7-inch E-Ink Display and Five Buttons

E-Ink 2,7"

The clear display shows the current temperature, humidity, and HVAC system operating status.

5 Buttons

The user can locally change the temperature, system mode, fan mode, and other available settings.

Customisation

Button functions can be customised, while Child Lock restricts unauthorised setting changes.

Up to 8 Local Temperature Control Plans

The WT401 allows up to eight operating plans to be programmed, enabling the temperature to be automatically adjusted for different times or room usage patterns.

The schedule operates locally, allowing the basic control strategy to be executed without a continuous connection to the supervisory platform.

Thermostat Designed for Centralised Management

Multicast

Makes it easier to send commands simultaneously to a larger group of devices in extensive installations.

FUOTA

Firmware Update Over-the-Air enables remote firmware updates for the device.

External Sensor Mode

The thermostat can use data from an external temperature source, depending on the system configuration.

NFC, Bluetooth 5.0 and LoRaWAN Downlink

Local configuration can be performed using the Milesight ToolBox app via NFC or Bluetooth 5.0.

Device parameters can also be changed remotely via LoRaWAN downlink messages, making larger deployments easier to manage.

Batteries, USB-C, 24 V or PowerBus

2 × 2700 mAh

Two replaceable ER14505 batteries enable completely wireless installation.

USB-C 5 V

The USB Type-C port can be used as an alternative power source or console port.

24 V

24 V AC/DC power is also available via a two-pin connector, as well as PowerBus with a compatible Milesight controller.

The individual power supply methods should not be used simultaneously.
