5.3 PERIODIC TEMPERATURE READING (DATALOGGING)
The Datalogging mode enables periodic logging of temperatures at each input (by selecting the precision
index for PT100 and PT1000 probes) (see chapter 5.1.1).
The frequency of these readings may be set in three modes:
 index logging in time steps
This type of datalogging is used to log the index value for each input at periods ranging from one
minute to over thirty hours. The time of the first logging may be set with a parameter.
When the datalogging mode in time steps is enabled, the system only logs the memorised index
values as soon as the preset time is attained; and this until the datalogging mode is disabled.
 index logging once a week
This type of datalogging is used to log the index value for each input once a week. The time and day
of the week logging is carried out may be set with a parameter.
 index logging once a month
This type of datalogging is used to log the index value for each input once a month. The time and day
(from 1 to 28) logging is carried out may be set with a parameter.
The system does not manage changes in the number of days in a month.
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.
