6.1.5 Definition of the module control bytes
➢ Definition of the Operating Mode byte (0x01) :
MSB LSB
Operanting Mode
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
-
Threshold
Detection Mode
0 : successive mode
1 : cumulative mode
Low Threshold
Detection
0 : deactivated
1 : activated
High Threshold
Detection
0 : deactivated
1 : activated
Datalogging
00 : deactivated
01 : time steps
10 : once a week
11 : once a month
Stop Mode of the
Datalogging
0 : permanent loop
1 : stop memory full

Attention, it is advised the greatest prudence when modifying the parameter setting of the Operation
Mode variable. Indeed, the modifications on this variable generally requires the update of the associated
parameters.
Defautl value :
 WaveTherm – DALLAS : 0x0A
 WaveTherm – PT100 : 0x08
 WaveTherm – PT1000 : 0x08
➢ Definition of the Application Status byte (0x20) :
It is possible to reinitialize to zero the bits by a write to the Application Status parameter.

Probe fault on
sensor 2
0: not detected
1 : detected
Probe fault on
sensor 1
0: not detected
1 : detected
Remark : The probe fault bits are set only when a problem is detected on WaveTherm – PT100, and
WaveTherm – PT1000 probes.
