The Xtrasun LT1 Lighting Controller (XTC1100) provides dual zone lighting control for use with Xtrasun double-ended fixtures. The LT1 is capable of controlling up to 160 fixtures (80 for each zone). The LT1 controller is specifically designed for use with Xtrasun XTDEKT1 and XTDEOKT1 lighting fixtures, which use 0-10v dimming and have the proper RJ14 ports for compatibility. The LT1 controller has an intuitive, easy to use color touch screen display. Each controller incudes two temperature and humidity sensors (one for each zone), mounting hardware, all necessary cables, one external cage clamp adapter, and one power supply. In addition to controlling the on/off scheduling of the light systems, the LT1 controller offers temperature based dimming, auto shutdown for extreme temperature situations, sunrise/sunset simulation, and connections for external equipment such as dehumidifiers and air conditioning systems.
