3.2 READ TEMPERATURES
The WaveTherm module has the following possibilities:
To read the current temperature ;
To transmit the last N temperatures stored, in one frame.
If two temperature sensors are used, then the WaveTherm return the last N/2 values of each sensor.
•
WaveTherm – DALLAS :
N = 48 temperatures
•
WaveTherm – PT100 :
N = 24 temperatures
•
WaveTherm – PT1000 :
N = 24 temperatures
3.3 PERIODIC TEMPERATURE READING (DATALOGGING)
Periodic reading of temperatures is available in two versions. In both cases, the module may be configured to
store the temperatures measured periodically (in time intervals ranging from a minute to several hours), once
a week or once a month.
➢
Standard datalogging :
Periodic collection of temperature measurements up to N temperatures. In this case, it functions in
'permanent loop'
mode, i.e. the most recent measurements replace the oldest measurements.
WaveTherm – DALLAS :
N = 48 temperatures;
WaveTherm – PT100 :
N = 24 temperatures;
WaveTherm – PT1000 :
N = 24 temperatures.
➢
Advanced datalogging:
Periodic collection of temperature measurements up to M temperatures. In this case, it functions in
'stop memory full'
mode.
WaveTherm – DALLAS :
M = 4500 temperatures;
WaveTherm – PT100 :
M = 2000 temperatures;
WaveTherm – PT1000 :
M = 2000 temperatures.
Remark :
Only the 'Stop memory full' mode is currently operational : when the memory corresponding to N
temperatures is full, datalogging stops automatically.
A new parameter setting cycle must then be started with a specific radio command.
A future upgrade will enable permanent looping with indication of looping.
