Interface Overview - Carrier WeatherMaster Series Installation Instructions Manual

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. 52 and Table 6 to locate the wiring terminals for each S-
Bus sensor.
Use Fig. 52 and Table 7 to set the DIP switches for the de-
sired 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 failures (except SAT) will be
issued and no economizing function will be available.

When using a CO
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 sensor OR make sure the ground for the
2
power supplies are common. See Fig. 53 for CO
wiring.
