CA controller
Simna CA is a controller designed for air handling units (AHU) and supports various system configurations. AHU can either be with or without heat exchanger, have a recirculation section and be single or double air flow with direct or constant air volume (CAV) control using integrated pressure sensors. At one time, up to 2 heaters and 2 different types of coolers can be controlled by selectable priorities and can be further expanded by modules.
All functionality is pre-programmed and ready to use. Only simple configuration is required using integrated web server menu.
CA controller is designed for convenient and energy efficient regulation of the air handling unit (AHU).
