S--Bus Sensor Wiring
The labels on the sensors and controller are color coded
for ease of installation. Orange labeled sensors can only
be wired to orange terminals on the controller. Brown
labeled sensors can only be wired to S--bus (brown)
terminals. Use Fig. 7 and Table 3 to locate the wiring
terminals for each S--Bus sensor.
Use Fig. 7 and Table 4 to set the DIP switches for the
desired used of the sensor.

NOTE: When a S--bus sensor is connected to an existing
network, 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
failures (except SAT) will be issued and no economizing
function will be available.

Sensor Wiring
When using a CO
2
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 power the CO
2
sensor OR make sure the ground
for the power supplies are common. See Fig. 8 for CO
2
sensor wiring.
