Sensor Transmission Time and Temperature Variables
Sensor transition time variables are as follows:
• The maximum time between sensor temperature transmissions is 15 minutes.
• The minimum time between sensor temperature transmissions is 30 seconds.
• The minimum time for transmitting temperature setpoint changes is 10 seconds.
Note: If a sensor transmits a message to the receiver and the receiver does not reply,
the sensor will retransmit the message to the receiver every 30 seconds until
communication to the receiver is re-established.
Sensor temperature time variables are as follows:
• The minimum change in zone temperature required to force a sensor transmission
is:
– 0.2°F (0.11°C) when the temperature range is between 60°F (15.6°C) and 80°F
(26.7°C)
– 0.5°F (0.28°C) when the temperature range is between 32°F (0°C) and 60°F (15.6°C)
or between 80°F (26.7°C) and 122°F (50°C))
• The minimum change in temperature setpoint required to force a sensor
transmission is:
– 1°F (0.56°C) for a model WZS sensor
– 0.1°F for model WZS sensor
– 0.1°C for a model WDS sensor
Operating Mode (Model WDS)
This section describes how to operate the Trane wireless sensor, model WDS. Figure 8
shows an example of a model WDS that has been configured and is in operating mode.
