Star(*)/Double Star(**) Function; End-Of-Range Temperature Values - Trane WDS Installation, Operation And Maintenance Manual

Operation

Star(*)/Double Star(**) Function

The star/double star function is available on models WDS and WZS. Consult the
appropriate unit controller documentation for information about this function.
The WZS sensor set supports star(*) and double star(**) on the sensor thumb wheel
(Figure

•
Figure 7.
The WDS sensor set supports star(*) and double star(**) functions if the sensor is
configured for single setpoint operation. Press the up or down arrow on the keypad to
display the star(*) or double star(**), respectively, on the sensor display.

End-of-Range Temperature Values

Receiver: The end-of-range temperature limits of the receiver for all models are 32°F to
122°F (0°C to 50°C). The receiver cannot replicate temperature values outside this range.
If the sensor transmits a temperature value to the receiver that is out of the receiver
replication range, the receiver will "freeze" the output at the end-of-range values. This
value will remain frozen until the transmitted temperature moves to between the end-of-
range temperature limits.
Sensor: The end-of-range temperature setpoint limits for the model WDS sensor is 50°F
(10°C) to 89.6°F (32°C). The end-of-range temperature setpoint limits for the model WZS
sensor is 45°F (7.22°C) to 95°F (35°C).

Star(*): A value of 95ºF (35ºC) is communicated.
Double star(**): A value of 44.6ºF (7ºC) is communicated.
WZS sensor: Thumb wheel
If the setpoint is increased one increment above 89.6ºF (32ºC), the star (*) appears. A
value of 95ºF (35ºC) is communicated.
If it is decreased one increment below 50ºF (10ºC), the double star(**) appears. A
value of 44.6ºF (7ºC) is communicated.
