Product ID: OS-750D

Occupancy Sensor

The OS-750D is an occupancy sensor developed for automatic control of HVAC operation. This sensor is designed for recess mounting with EURO standard single switch box with 60.0 mm screw pitch.

An innovative dual delay processor makes this sensor smart enough to verify the nature of occupancies. In addition to the HVAC operation control, this duplex occupancy sensor also provides signal for instant light control.

With one installation, the OS-750D can offer both HVAC and lighting controls to maximize the benefits of occupancy-oriented building energy management system.
