Operation

 

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.
