Grozone LS1 Light & High-Load Switcher — 120V The Grozone LS1 is a 120V load switcher made for controlling high-current equipment such as HID grow lights, high-amperage heaters and dehumidifiers. It uses a low-current 120V sense cord to activate the connected equipment. The sense cord can be controlled by a regular timer, allowing the timer to trigger the LS1 instead of directly switching the high-current load. For Indoor Gardening Indoor gardeners can use the LS1 to control compatible 120V HID lighting from a regular timer. The timer activates the LS1 through its low-current sense cord, while the LS1 performs the high-current switching required by the lighting equipment. For Hobby Grow Rooms In a hobby grow room, the LS1 can be used with compatible: HID grow-lighting equipment High-amperage heaters Dehumidifiers The LS1 does not decide when the equipment should operate. Its sense cord must be activated by a regular timer or another compatible 120V control output. For Hobby Greenhouses Hobby greenhouse growers can use the LS1 to switch compatible 120V heaters or dehumidifiers when those loads require a separate high-current switching device. The operating schedule or environmental response is determined by the timer or controller connected to the LS1’s sense cord. The LS1 itself is not a thermostat, humidistat or programmable timer. For Indoor Plant Rooms Plant collectors maintaining a dedicated indoor growing room can use the LS1 with compatible HID lighting, heaters or dehumidifiers. This can be useful when a regular timer is being used to activate equipment that should be switched through a dedicated high-load device. How the LS1 Works Compatible equipment is connected to the LS1. The LS1’s 120V sense cord is connected to a regular timer or compatible controller. When the timer supplies power to the sense cord, the LS1 switches the connected load on. When the timer stops supplying power to the sense cord, the LS1 switches the connected load off. Key Features 120V supply and 120V output configuration Designed for high-current electrical loads Suitable for compatible HID lighting, high-amperage heaters and dehumidifiers Low-current 120V AC sense cord Sense cord can be activated by regular timers Additional LS1 units can be installed when more loads must be controlled Important Before connecting any equipment, confirm that its voltage, current and load type are compatible with the LS1 and with the electrical circuit supplying it. Installation and use must comply with applicable electrical codes and the product instructions. A sense cord is the small control plug on equipment such as a Grozone LS1 light controller. It does not power the grow lights themselves. You plug the sense cord into a regular 120 V timer or environmental controller: Timer outlet turns on → the controller detects power on the sense cord and switches the connected lights on. Timer outlet turns off → the controller switches the lights off. This lets an inexpensive timer control a large electrical load without forcing all the lighting current through the timer. The heavy power is supplied separately to the controller; the sense cord only provides the on/off signal.
