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

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 8.
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.
