COOL ONLY, 3 WIRE CONTROLLER WITH SELECTABLE FAN

GENERAL DESCRIPTION

The DSL-150 controller is designed for new or replacement applications of "cooling only" systems. The DSL-150 represents the latest in solid-state surface mount electronics and manufacturing techniques incorporated into a extremely low profile, ultra-slim white ABS plastic case. The DSL-150 offers "user friendly" control of cooling equipment along with an easy-to-read vertical LCD that displays complete operations status. A direct-wire, easy to-install subbase mounts on a standard vertical outlet box or any dry wall surface using anchors and hardware provided.
