The CU24V2 controller is a configurable controller for HVAC AHUs. The rich configuration options of the controller allows to create applications for AHU in almost all configurations. The controller comes complete with a 4.3” wall-mounted color touch panel RMC30, which allows you to create applications, parameterize the controller and manage the unit. The panel has a built-in very innovative and intelligent interface that allows the user to easily and clearly program the controller and navigate in the menu system. It has a unique solution consisting of a built-in guide, which during navigation in the menu, prompts the user how to use the buttons and explains the parameter designations, so there is no need to consult the instructions. When creating an application, the user only selects which functions he wants to use, while the controller sets the input/output for the task depending on the selected other functions, then the selection is displayed on the panel in real time. The I/O list of the built application along with the description and visualization is made available and can be consulted when connecting devices to the controller.
