The VentLogic V40 controller is designed for full automation of electrically operated side curtain systems. VVS curtain positioning is completely controlled by temperature, wind speed, wind direction and rain sensors to ensure that the climate within the building is continually optimised. One V40 can control up to four openings and each opening can have different parameter settings for total flexibility.
