Description
The TSU is a standalone 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.
Featuring an external humidity sensor input for accurate humidity control,
this comprehensive unit also provides a dehumidification sequence
compensated by auto activation of reheat output.
The controller is available with additional sensors, such as the PIR motion
detection and humidity sensor, providing more functionality for the terminal
device.
Features
• Fan control: 1, 2 or 3-speed (auto/on), or analog (ECM)
• Optional internal/external humidity sensor input for simple and accurate humidity control
