Smart Heating and Cooling Control

Milesight WT303-868M is a smart LoRaWAN thermostat designed to control 2- and 4-pipe FCU fan coil units with 3-speed fans. It supports 2- and 3-wire ON/OFF motorised valves in 2-pipe installations and 2-wire ON/OFF valves in 4-pipe installations.

The WT303 features a 2,7-inch E-Ink display, built-in temperature and humidity measurement, an input for an external NTC sensor, and a digital input for applications such as a hotel key card or reed switch. Local schedules, open-window detection, freeze protection, Milesight D2D, and LoRaWAN Class C communication enable advanced HVAC control systems and BMS integration.

Milesight WT304-868M is a smart LoRaWAN thermostat designed to control 2- and 4-pipe FCU fan coil units. It supports installations with 3-speed and 0–10 V EC fans and, depending on the system configuration, 0–10 V proportional valves and ON/OFF motorised valves.

The thermostat features a 2,7-inch E-Ink display, built-in temperature and humidity measurement, an NTC input, and a digital input for a hotel key card, reed switch, or other dry contact. Local schedules, open-window detection, freeze protection, Milesight D2D, and LoRaWAN Class C enable advanced HVAC control systems and BMS integration.

Milesight WT101-868M is a smart LoRaWAN radiator thermostat designed for precise temperature control in individual rooms. The built-in NTC sensor measures temperature within a range of −20…+60°C, while the stepper motor automatically controls the radiator valve opening level.

The WT101 supports automatic temperature control, direct valve opening control, up to 16 heating plans, open-window detection, freeze protection, and Child Lock. Two replaceable Li-FeS₂ AA batteries provide approximately 8 years of operation at SF7/EU868 under the manufacturer's test conditions.

Milesight WT102-868M is a self-powered smart LoRaWAN radiator thermostat that uses radiator heat energy to power its electronics and valve actuator. Thanks to energy harvesting technology, the device does not require periodic battery replacement or a permanent wired power source.

The WT102 measures temperature within a range of −20…+60°C, automatically controls the valve opening and allows the target temperature to be set within a range of 5…35°C. It supports up to 16 heating plans, open-window detection, freeze protection, storage for 1000 records, LoRaWAN Class B, NFC configuration, and an optional external NTC sensor connected via USB-C.

Milesight WT201-868M is a smart LoRaWAN thermostat designed to control most HVAC systems powered by 24 V AC, including heat pumps, air conditioning systems, furnaces, boilers, and PTAC units. The device supports heating, cooling, Emergency Heat, Auto mode, and fan control.

The WT201 features a 4,2-inch backlit LCD display, built-in temperature and humidity measurement, a digital input for a hotel key card or reed switch, and storage for 1000 records. LoRaWAN Class C, Milesight D2D, local schedules, freeze protection, Multicast, and FUOTA enable integration of the thermostat with modern Smart Building and BMS systems.

Milesight TRA3015 is a valve adapter set designed for the Milesight WT101 smart radiator thermostat. It allows the thermostat to be installed on popular valves that do not use the standard M30 × 1,5 mm connection.

The set extends WT101 compatibility to Danfoss RA, RAV and RAVL, Giacomini GIA, and M28 × 1,5 mm valves used by manufacturers including Comap, Herz, and TA. The adapters make it possible to use one thermostat model in installations equipped with different types of radiator valves.

Milesight WT401-868M is a wireless smart LoRaWAN thermostat designed to control and monitor HVAC systems in offices, hotels, retail stores, and residential buildings. The device features a 2,7-inch E-Ink display, built-in temperature and humidity measurement, and a PIR occupancy sensor with a range of up to 6 m.

The WT401 supports local schedules, up to 8 operating plans, heating and cooling modes, fan control, and occupancy-based energy-saving functions. It can be powered by two replaceable 2700 mAh batteries, 24 V AC/DC, USB-C 5 V, or PowerBus, and can work with HVAC systems via LoRaWAN and compatible Milesight controllers.
