Designed for heavy skylights (160 lb. hatch weight), this digital system features a power conversion built right into the control package that accepts direct connection of line voltages. Power protected memory eliminates the need to reset the motor after a power outage. ETL listed and CE approved, the remote can control an infinite number of windows, skylights and even motorized blinds. The Sentry II HS Motor System features a rain sensor, which automatically closes skylights at the first sign of moisture. Available remote control utilizes rolling code technology to provide high security and peace of mind. A built-in thermostat allows skylights to open and close together.
