  • Product Description

    The RS-OSC and RS-OSW are occupancy sensors designed for automatic occupancy control of your HVAC system. They can be a wall, corner or ceiling mount to provide the best detection area for each application. The sensors provide an occupied/unoccupied signal to all RS-300 thermostats with CLK1/CLK2 terminals. A 4-wire cable (thermostat cable or CAT5) is all that's needed for connection.

    The RS-OSC and RS-OSW occupancy sensors are perfect for partial use rooms and areas in just about any facility. In office spaces, schools, worship facilities, and portable buildings, the adjustable Verify Occupancy setting allows random in-and-out occupancy and cleaning personnel to come into the area for a short period of time without the sensors triggering the HVAC unit back into occupied mode. The sensors are designed to be used with the commercial keypad lockout feature of the RS-300 thermostats.
