The CRXSL wireless controller is slim and designed for wall recessing. It seamlessly manages all RX or SL heater models. It’s mains-powered, compatible with standard double gang boxes, and features a large, backlit LCD display for easy reading. It allows for six daily temperature adjustments across the week.
It includes an optional open/close window detection feature which reacts intelligently to temperature changes in the area or room, turning off the heating to save energy when it senses a sudden drop from an open window or door. It restarts once the window or door is shut. Settings for detection time and temperature can be customised in the setup menu.
