Important: The maximum wire length for the external sensor should be limited to 100 feet low capacity
cable (25pf/ft or less).
Note: If you have more than one sensor associated to the same unit controller, by default the
temperatures will average. This is undesirable if using the external sensor for refrigeration or
freezer monitoring. Some work will be required in Tracer TU to create a new point and remove
the refrigeration temperature from space temperature averaging. See “WCS-SB/R Refrigerator
Temperature Sensor Setup,” p. 93 section in the Using the Tracer® TU Service Tool with a
Wireless Network chapter.

Note: When installing the WCS-SB/R sensor in a refrigerator or freezer where the temperature may
fluctuate, we recommend using a Thermobuffer to slow down the temperature change. This will
help preserve the battery life of the sensor.
