Neptronic TUCB24C6X2 Installation Instructions Manual

Model
TUCB24C6X2
with Internal Temperature Sensor
TUHB24C6X2
with Internal Temperature and Humidity Sensor
Description
The TUCB24C6X2 / TUHB24C6X2 is a Universal Wall-Mount
Controller with built-in temperature sensor and scheduler. The unit
is designed for simple and accurate control of a heat pump or other
heating/cooling equipment. Its field configurable algorithms enable
versatile implementation of required control sequences.
The TUCB24C6X2 / TUHB24C6X2 also provides an external
humidity sensor input for simple and accurate humidity control and
provides a dehumidification sequence compensated by auto
activation of reheat output.
