Fig. 68 — S-Bus Sensor DIP Switches
Use Fig. 68 and Table 19 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.

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. 69 for CO
