ControlsWiring the wall-mounted CO2sensorDVC setpoint potentiometer oneconomizer module can be adjustedas follows:0% - 500ppm, 50% - 1000 ppm,100% - 1500ppmThe outside air damper willmodulate from minimum positionsetting to up to 100% whileattempting to maintain the CO2setpoint.Wiring the duct-mounted CO2sensor1. Connect the common wire fromthe controller to the groundterminal (terminal 0) (Figure 16).2. For voltage output, connect thesignal wire to terminal V.3. Connect the power according tothe guidelines in Power supplyrequirements.Figure 15 - Wall-mounted CO2 sensor wiringFigure 16 - Terminal connections and LED locations21341 = Outer jumper2 = Power terminal3 = Ground terminal4 = Output terminals36RT-SVX20B-E4
