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).
