thermostats

The UX400 is a versatile 4-inch high-resolution full touchscreen thermostat designed to adapt to diverse control needs. It can function as a Modbus slave thermostat, communicating temperature and status data to a master controller, or operate as a standalone thermostat managing local control independently. Additionally, the UX400 supports wireless data transmission to UnitexControls connected to Fan Coil Units (FCUs), providing flexible deployment options in building automation systems.
