Use Fig. 80 and Table 26 to set the DIP switches for the desired
use of the sensor.
NOTE: When an S-Bus sensor is connected to an existing net-
work, it will take 60 minutes for the network to recognize and
auto-configure itself to use the new sensor.
During the 60 minute setup period, no alarms for sensor fail-
ures (except SAT) will be issued and no economizing function
will be available.

sensor, the black and brown common wires
are internally connected and only one is connected to “IAQ
COM” on the W7220. Use the power from the W7220 to pow-
er the CO
2
sensor OR make sure the ground for the power sup-
plies are common. See Fig. 81 for CO
