Neptronic Networkable Wall-Mount Controller

Models

The TSUB is a universal wall-mount controller with a built-in temperature sensor. The unit is designed for simple and accurate control of a fan coil unit or heating/cooling equipment. Its field configurable algorithms enable versatile implementation of required control sequences.

The controller is available with additional sensors, such as the PIR motion detection and humidity sensor, providing more functionality for the terminal device.
