3 PRE ENTATION OF THE WAVETHERM MODULE FUNCTIONALITIE
3.1 SENSORS INTERFACE
➢WaveTherm – DALLA :
The m dule is designed t manage t the maximum tw DALLAS temperature sens rs (type
DS18B20).
This DALLAS sens r f 1-wire type integrates a 12-bit internal c nverter.
Each external sens r is c nnected t the m dule by a cable equipped with a BINDER c nnect r f
3-pin type.
An aut matic identificati n f the temperature sens rs all ws t mem rize the identifier f the
sens rs. This phase is aut matically carried ut when p wering the m dule
and is als activated n a specific radi request (in this case, The m dule returns by radi the
identifiers f the sens rs).
➢WaveTherm – PT100 :
The WaveTherm-PT100 m dule has the p ssibility t manage 1 r 2 PT100 temperature sens rs.
The pr bes are c nnected t the m dule thr ugh impervi us c nnect rs all wing t c nnect 2, 3 r 4
wires pr bes.
➢WaveTherm – PT1000 :
The WaveTherm-PT1000 m dule has the p ssibility t manage 1 r 2 PT1000 temperature sens rs.
The pr bes are c nnected t the m dule thr ugh impervi us c nnect rs all wing t c nnect 2, 3 r 4
wires pr bes.

3.2 READ TEMPERATURES
The WaveTherm m dule has the f ll wing p ssibilities:
T read the current temperature ;
T transmit the last N temperatures st red, in ne frame.
If tw temperature sens rs are used, then the WaveTherm return the last N/2 values f each sens r.
•WaveTherm – DALLAS : N = 48 temperatures
•WaveTherm – PT100 : N = 24 temperatures
•WaveTherm – PT1000 : N = 24 temperatures
3.3 PERIODIC TEMPERATURE READING (DATALOGGING)
Peri dic reading f temperatures is available in tw versi ns. In b th cases, the m dule may be c nfigured t
st re the temperatures measured peri dically (in time intervals ranging fr m a minute t several h urs), nce
a week r nce a m nth.
➢tandard datalogging :
Peri dic c llecti n f temperature measurements up t N temperatures. In this case, it functi ns in
'permanent loop' m de, i.e. the m st recent measurements replace the ldest measurements.
WaveTherm – DALLAS : N = 48 temperatures;
WaveTherm – PT100 : N = 24 temperatures;
WaveTherm – PT1000 : N = 24 temperatures.
➢Advanced datalogging:
Peri dic c llecti n f temperature measurements up t M temperatures. In this case, it functi ns in
'stop memory full' m de.
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.

3.4 MANAGEMENT OF THRESHOLD ALARMS
The WaveTherm m dule detects when the values exceed the thresh ld levels (high r l w) f r a given peri d
f time.
The WaveTherm – PT100 and PT1000 may be c nfigured with a precisi n level ffering a m re reliable
measurement even in envir nments with excessive interference (see chapter 7.2.1).
Three types f thresh ld alarm detecti n meth ds may be pr grammed :
immediate thresh ld alarm detecti n
thresh ld alarm detecti n f r a given c ntinu us peri d f time (successive m de)
thresh ld alarm detecti n f r a t tal peri d f time (cumulative m de)
3.4.1 Threshold Alarm Detection
Thresh ld alarm detecti n requires peri dic measurement f the temperature f r a predefined peri d. The
value f this peri d enables establishment f the thresh ld alarm detecti n reactivity.
This period is set independent of the datalogging period. However for power saving reasons it is
recommendable to set the datalogging period as a multiple of the threshold alarm detection period.
The f ll wing parameters apply t this functi n:
High thresh ld alarm,
L w thresh ld alarm,
Thresh ld excess time (used in cumulative and successive m de),
M de parameter setting byte (high thresh ld enabled, l w thresh ld enabled, immediate,
successive r cumulative m de).
3.4.2 Storage of Threshold Alarm occurences
Thresh ld alarms are st red in a mem ry z ne which may be accessed by radi . If the number f thresh ld
alarms exceeds the mem ry st rage capacity, the ldest alarms rec rded are deleted.
The f ll wing inf rmati n is rec rded in the table:
Thresh ld alarm detecti n date
Thresh ld alarm detecti n durati n
The average value f all measurements rec rded during the alarm peri d.
3.4.3 Transmission of a Threshold Alarm Frame
The m dule may be pr grammed t transmit a radi frame as s n as a thresh ld alarm is detected.

3.5 STORAGE OF CALIBRATION PARAMETERS
The WaveTherm m dule manage a n n-v latile mem ry area accessible by radi c mmand, and all wing t
st re up t 32 bytes.
This area is n t used by the internal pr cess, and is generally used t st re the parameters relative t the
calibrati n f the m dule, and can be read, r m dified by specifying the start address, and the size f the
data.
3.6 WAKE-UP SYSTEM MANAGEMENT
In rder t reduce m dule p wer c nsumpti n, a wake-up peri d parameter setting system is inc rp rated.
This system enables m dificati n f the m dule wake-up peri d (default setting 1 s) by entering a time and
day f the week :
The wake-up peri d default value may be m dified;
Tw time-wind ws with different wake-up peri ds may be defined;
Each day f the week may be set in ne f the f ll wing three cases :
•Wake-up peri d default setting
•Wake-up acc rding t predefined time wind ws
•N wake-up peri d (f r safety reas ns, the m dule is n t disabled n recepti n and it
wakes up every 10 sec nds)
Note : The system is disabled by default and must be enabled by writing a specific profile in the
wake-up system status word.
3.7 AUTOMATIC TRANSMISSION OF FAULTS
The WaveTherm m dule ffers the p ssibility t aut matically transmit radi frames when an ccurrence is
detected.
The f ll wing ccurrences may pr v ke an aut matic alarm:
Thresh ld detecti n (see chapter 7.6)
End f battery life detecti n (see chapter 7.8)
Pr be fault detecti n (WaveTherm – PT100 and PT1000 only)
It is p ssible t select f r each type f ccurrence whether r n t an alarm frame is t be sent.
The radi address f the receiver m dule and the repeater path must be preset with a radi signal.
