    Description

    WT201 Description

    Overview

    The WT201 is a LoRaWAN smart thermostat used as an HVAC controller for a wide range of heating and cooling systems. It enables precise temperature adjustment through scheduled programming and remote management, with real-time alerts for sudden temperature changes.

    Wide HVAC Compatibility

    The WT201 works with most 24VAC HVAC systems, including furnaces and air conditioners (2H/2C), heat pumps, boilers and PTAC devices, offering heat, emergency heat, cool and auto modes plus three fan modes.

    Display & Sensing

    A 4.2-inch LCD continuously shows room status, while the embedded temperature and humidity sensor monitors the ambient environment for accurate control.

    Flexible Control & Schedules

    Seven working modes with up to 16 schedules each allow manual or automatic regulation, with time-zone and summer/winter time support for different regions.

    Hotel & Integration

    The WT201 integrates with hotel room-card systems and supports Milesight D2D for gateway-free control, BACnet via Milesight gateways, and multicast for bulk management.

    Reliability

    An RTC keeps time for 72 hours without power, and local storage of 1,000 entries with retransmission prevents data loss. NFC enables one-touch configuration and FUOTA keeps firmware current.

    Industry Applications

    WT201 Industrial Applications

    Commercial Buildings

    Offices and common areas control 24VAC HVAC with schedules and remote management, while real-time alerts flag sudden temperature changes to protect people and assets.

    Hospitality

    Hotels integrate the WT201 with room-card systems for automatic comfort and energy savings, with child lock and anti-theft installation for guest areas.

    Smart HVAC Retrofit

    Compatibility with furnaces, heat pumps, boilers and PTAC makes the WT201 a flexible upgrade, with BACnet and D2D integration into building systems.

    Energy Management

    Built-in temperature and humidity sensing plus scheduling reduce energy use, and LoRaWAN backhaul feeds data into energy-management platforms.
