The C.A.P. Day/ Night Variable Fan Speed Controller (VSC-DNe) is designed to gradually increase or decrease the speed of centrifugal fans depending on the day or night temperature set-points.
The VSC-DNe enables you to determine precise temperature levels to achieve within your growing environment by way of proper ventilation. The temperature differential switch can be set at 3°, 5° or 7°F and comes complete with a 12-foot probe.
The day and night temperature knobs can be set between 50°F and 100°F independently. The built in photocell will automatically sense day or night and adjust the speed of your fan accordingly.
