Time Synchronisation Function
XTERNA broadcasts every 10 minutes. After configuring your clock,
please be patient in waiting for the first Synchronisation. Upon
synchronisation the yellow LED D7 will illuminate. Remember to set
DST (‘Summer Time’) with the DST button.
6.5
Temperature Display
The temperature is also transmitted with the time. Therefore,
temperature will not be displayed until after the first
synchronisation.
Set Celsius or Fahrenheit using parameter 29:
Fahrenheit: 1
Celsius : 2
Temperature is displayed between 30 and 35 seconds past each
minute. Celsius is displayed with 0.5 °C resolution. Fahrenheit is
displayed with 1 °F resolution.
Positive and negative temperature is indicated by the left hand
neons: Neon indicator PM2 acts as a decimal point.
6.6
Temperature Validity
If no valid data is received on the next scheduled sync (every 10
minutes), the temperature will be deemed to be old and invalid.
Temperature will not be shown until a new valid temperature is
received.
