G.A.S. AC-EC controller is the ultimate fan controller offering control over intake and exhaust fans, with separate day and night settings. The digital sensor monitors the temperature, light and humidity whilst the controller automatically maintains the environment to the required settings.The combination of the E.C. and A.C. enables control of all professional fans, and the built-in fan balancer enables negative pressure to be established accurately to 1% of fan speed. The intake fan will remain off until the temperature or humidity increases, at which point the fans ramp up, saving energy and reducing wear on the ventilation system. The settings in the controller also allow for minimum and maximum fan speeds to be set.• Temperature and humidity control• Set maximum and minimum fan speeds• Set day and night temperature and humidity • Set negative pressure• Plugs directly into all Systemair’s A.C. and E.C. fans• Requires E.C. cables, supplied separately
