Overview
WT201 overview
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.
