22 Before wiring the CCN connection, refer to the Connect to the CCN Communication Bus section on page 26, for commu-nication bus wiring and cable selection. The cable selectedmust be identical to the CCN communication bus wire used forthe entire network. The other end of the communication bus cable...

24 The CO 2 sensors (33ZCSENCO2) factory set for a range of 0 to 2000 ppm and a linear voltage output of 0 to 10 vdc.Figure 19 shows ventilation rates for various CO 2 set points when outside air with a typical CO 2 level of 350 ppm is used. Refer to the instructions supplied with the CO 2 sensor fo...

25 Indoor Air Quality Sensor Wiring — To wire the sensorsafter they are mounted in the conditioned air space and returnair duct, see Fig. 20 and the instructions shipped with the sen-sors. For each sensor, use two 2-conductor 18 AWG twisted-pair cables (unshielded) to connect the separate isolated 2...

26 7. Strip 1 / 4 -in. of insulation from each conductor and equip each with a 1 / 4 -in. female quick connect terminal. 8. Connect the RED wire to terminal +24v on the control board. 9. Connect the BLACK wire to terminal GND on the control board. 10. Connect the WHITE/CLEAR wire to terminal RH/IAQ ...

27 3. Connect the other end of the communication bus cable to the terminal block labeled CCN in the zone control-ler of the first air terminal. Following the color codein Table 3, connect the Red (+) wire to Terminal 1.Connect the White (ground) wire to Terminal 2. Con-nect the Black (–) wire to Ter...
