Wake-Up Interval and Redundant Transmission settings on the SED-THSU5045 thermostat.

Issue

How do the Wake Up Time and Redundant Transmission settings affect the operation of the SED-THSU5045 thermostat?

Product Line

SmartStruxure Lite

Environment

  • SED-THSU5045
  • Enocean

Cause

The function of the Wake-Up interval and the Redundant Transmission switches is not described in the documentation that comes with the sensor.
 

Resolution

DIP Switch 1 and 2 control the Wake-up Interval (in seconds)
OFF OFF No cycling wake up
ON OFF 1
OFF ON 10
ON ON 100

DIP Switch 2 and 3 control the Redundant Transmissions (in frequency of tx)
OFF OFF Every wake up
ON OFF 7 to 14 wake ups
OFF ON 70 to 140 wake ups
ON ON Never

 

The idea is that the stat will wake up when the wake-up interval is elapsed and verify if the temperature has changed by more than approximately 1°F. If it did, it will send a transmission, if not it will go back to sleep until the next interval.

The second setting (redundant transmission) will govern how often the stat will send a value, even if the temperature has not changed (as some kind of ping or keepalive).
