The iGS-10 cycle controller represents an easy and flexible solution to periodic control day and night. The integrated photocell can differentiate day and night and you can program different timing cycles for each. The iGS-10 will initiate the proper day or night periodic control. The unique Day/Night function allows the user to set different On/Off times per cycle, allowing you to specify the appropriate timing to maximize environmental control. The easy to read display makes setting your On/Off times a snap. Simply watch as the luminous bargraph lights up as you choose your On/Off times via the easy to use dial. Most PnG controllers come with a separate outlet box. The outlet box that comes with this PnG product has a CAT-5 jack on the side, an outlet in the front and a plug in the rear. The outlet box plugs into a wall outlet, then you plug the device you want to control into the outlet located in the front of the outlet box. Finally, a CAT-5 computer cable (included) is plugged into the outlet box and the other end gets plugged into controller itself. This cable allows the controller to turn on and off the device plugged into the outlet box and also supplies power to the controller.
