c-pro 3 AHU

Controller for single or double flow air handling units for large surface areas
c-pro 3 AHU is a highly configurable controllers for the management of single or dual-flow (with heat recovery) air handling units operating with three coils and an additional pre-heating coil. The coils can be electrical, water or direct expansion.
The controller is able to manage the return fan and the supply fan independently (up to 3 speeds or modulating according to the supply static pressure and according to the room air quality). Options include the management via serial port of the modulating fan (supply and return) by means of dedicated EVCO inverters or of Fan Walls with up to 16 EC fans for each flow.
The controller can manage the external damper, the bypass damper and the mixing chamber damper, as well as the humidifier, both in “on-off” and modulating mode.
Available in a 8 or 10 DIN-module format with up to 40 I/Os, the controller is compatible with a wide range of state-of-the-art user interfaces for panel or wall installation. Some of them have built-in temperature and humidity sensors.
