Description
WT304 is an advanced room thermostat specifically developed to oversee fan and valve operations in air conditioner applications where 2-pipe or 4-pipe fan coil unit (FCU) with 3-speed fan or ECM fan is adopted. It allows manual control by buttons, and automatic control through predefined logic, scheduled programming or remote management system. This ensures optimal comfort and energy efficiency in the controlled environment. With 2.7’ e-ink screen and embedded temperature and humidity sensor, the thermostat continuously displays the room status while monitoring the ambient temperature and humidity. It is compatible with standard LoRaWAN® gateway and Milesight Development Platform, enabling real-time monitoring of environmental status for effective remote management.
Features
- Applicable for 2-pipe and 4-pipe FCUs with 3-Speed fans or ECM fans
- Compatible with 2-wire On/Off relay, 3-wire On/Off relay or 0-10V valve control
- Supports intuitive 2.7-inch display, allowing for showing temperature/humidity and status of the room clearly
- Equipped with an external NTC sensor signal input and a dry contact input for key card/magnet switches
- Highly adapt to different scenarios with 60mm/86mm/118mm/120mm boxes
- Adjust the room temperature manually or automatically
- Optional data sources for environmental detection and accurate control: built-in temperature and humidity
- sensors, external NTC sensor, Milesight sensors, external sensor data from network servers
- Supports adding 8 plans and allow up to 16 schedules for each plan, ensuring various control needs and energy savings
- Supports open-window detection and freeze protection
- Supports the child lock function for safety reasons
- Function well with standard LoRaWAN® gateways and network servers
