Sensor Transmission Time and Temperature Variables

Time Variables

•

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. This 
feature makes re-establishing communication efficient. For example, if an 
HVAC unit is powered down (and, consequently, the receiver) for 
servicing, the sensor will rebroadcast the transmission every 30 seconds 
until the HVAC unit (and, consequently, the receiver) is powered back up. It 
will take no longer than 30 seconds for communication to be re-
established.

Temperature Variables

•

The minimum change in 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 0 °F (–17.8°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).
