The OS-550T is an occupancy sensor designed for automatic operation control of HVAC system. This occupancy sensor delivers a changeover relay contact output to control the HVAC operation according to the occupancy status of the area.

In addition to all standard features of OS-550, this sensor provides high/low temperature setbacks to prevent the room temperature becoming too high or too low during unoccupied period. The sensor can be wall or ceiling mounted with the mounting bracket.
