The CYGNUS-F is a simple climate computer with a winch motor control for air inlet valves, for example. These are controlled based on the measured temperature or negative pressure. The air inlet control can run synchronously with the ventilation. In addition, the CYGNUS-F is equipped with a pulse-pause system for the air inlet control. The CYGNUS-F is available in two designs, where a distinction is made between the CYGNUS-F1 (single-phase motor control) and the CYGNUS-F3 (three-phase motor control). The switches on the side allow you to take manual control of the winch motor.
