The TC300 series stand-alone digital fan coil thermostat is designed for temperature control in industrial, commercial and residential environments. The thermostat improves comfort and saves energy by comparing the room temperature with the desired setting. This information is used to control the fan coil unit.
TC300 features microprocessor-based control and a large LCD screen. The LCD display modes include operation status (cooling, heating, ventilation), fan speed, room temperature, and temperature setting.Features
