1. INTRODUCTION
1.1 Wireless monitoring devices
For the retrot of food refrigeration and room cooling systems, energy
consumption measurement and I/O management via supervisor, CAREL
proposes the rTM SE wireless system (Remote Temperature Monitoring). This
solution guarantees the maximum in terms of:
• Flexibility;
• Functions;
• Reliability;
• Easy operation
• Reduced installation costs;
• Easy commissioning/service;
• Integration with the most common BMS (Building Management Systems);
This solution ensures considerable savings in terms of installation costs
(eliminating the cost of wiring), oering exibility in the layout of supermarkets
and allowing faster retrot installation. Ideal for all installations where electrical
wires cannot be laid, i.e. properties that do not have raised oors or false
ceilings.
The retrot of existing systems is required for compliance with HACCP
standards, for monitoring the systems via remote connections, for
recording events and analysing them for scheduled maintenance.
The CAREL rTM SE system can be used in all industrial and trade businesses
that require the prevention of risks relating to the safety and storage of food
for human consumption, in accordance with the HACCP standards; moreover,
it oers the possibility to manage exible spaces very simply, thus reorganising
the layout of showcases in a supermarket without having an impact on the
wired network (communication and power supply);
The system is a network of wireless sensors tted inside the showcases, easy
to congure and install, connected to a Carel supervisor (PlantVisorPRO or
PlantWatchPRO) for recording the temperature, events and alarm notications.
The data measured and the alarms signalled are saved and can be accessed at
any time, in compliance with EN 12830.
The system can be easily installed on all types of refrigeration unit (showcases or
cold rooms), is independent of the controller installed on the unit and requires
no additional wiring because the devices are wireless and battery powered,
meaning signicant cost savings.
The sensors require no electrical connections as they use a long life battery
(typically 5 to 8 years, depending on the transmission frequency set), a wireless
connection with ZigBee™ technology (mesh) at a transmission frequency of
2.4 GHz authorised for operation in all countries around the world, and are
ready for connection to the most common BMS systems using Modbus®
protocol. The sensors monitor the inputs (temperature, humidity, light and
digital input status) and send the data wirelessly to the Access Point or Router.
Communication between sensors and the Access Point is two way. The
sensors, as well as sending the change in the status of the variables, can also
receive data.
Moreover, a mains powered model has been designed for use in all
applications that require frequent communication (e.g. monitoring oating
suction pressure).
In ambient monitoring applications, the temperature, humidity and light
intensity can all be recorded by simply installing battery powered sensors in
the desired location. The sensors cover a wide range of uses in refrigeration,
air-conditioning and humidication applications.
Many applications are also available for remote I/O management from
supervisors, as the module manages generic I/Os and saves on the cost of
laying cables, without the need for separate power and signal cables.
The wireless devices send the temperature and alarm data wirelessly to the
Router and Access Point, which relay the information to the supervisory system
The CAREL rTM SE system consists of the following components:
• Battery powered devices:
- Temperature sensor from tted inside the showcase, version BP SE (Built-
in Probe);
- Sensor with two external NTC probes and two digital inputs, version EP
SE (External Probe) for showcases and cold rooms;
- Room temperature and humidity sensor for installation in residential
environments, version SA
- Temperature, humidity and light sensor, SI industrial version;
- Pulse counter to be used with the energy meter module congured for
pulse counters, version CI;
• Access Point. Wireless receiver that acquires data from the various sensors
in the ZigBee™ network, making such data available to the supervisor via
Modbus® RTU over RS485. Up to 30 sensors can be directly associated with
each Access Point, or a maximum of 60 if one or more Routers are used. The
supervisor (PlantVisorPRO or PlantWatchPRO) can thus see all the variables
in the rTM SE system;
• Router. To be used when the distance between the Sensors and the
Router exceeds 30 m (relays the wireless signals so as to cover greater
distances between the Access Point and sensors), or if there are more
than 30 Sensors in the network. There can be a maximum of 60 Routers in
the wireless network, 48 of which are visible to the supervisor. The Access
Point automatically assigns a serial address in the order in which these are
“bound”, starting from 200 up to 247. Five versions of Router are available,
which also include other functions:
- Router powered at 230 Vac mains voltage, version RO;
- Router Bridge powered at 12-24 Vac, version RB. Integrates the function
to extend the RS485 network;
- Router Sensor powered at 12-24Vac, version EP1. Integrates the functions
of the battery powered EP SE Sensor);
- Router-Actuator powered at 12-24 Vac, version RA. Integrates the
functions of I/O module or local thermostat;
- Router-Pulse Counter powered at 12-24 Vac, version RC. Integrates the
same functions as the CI battery powered pulse counter;
• Modbus® supervisor system: The rTM SE system is designed to be used
together with Carel PlantVisor PRO or PlantWatch PRO supervisors
Wireless transmission between the various devices uses standard ZigBee™
communication protocol and encryption technology with a Carel private key.
This is an advanced system that has achieved an excellent level of security in
data exchange for wireless communication and is used in many applications.
The CAREL solution uses mesh technology between Access Points and
Routers, ensuring more reliable communication and delivery of the data sent
by the sensor.
Note: ZigBeewireless connection without interoperability.
rTM SE handheld: network analyser used to check the ZigBeewireless signal
level and to open/close the wireless network when binding the devices
(sensors and Routers), including the possibility to set the BP Sensor address
and reset the Router and Access Point. Useful during installation;

1.3 Terminology
Wireless
Wireless means“without wires”, in contrast to the term wired.
Wireless network
Communications system (series of devices, appliances, methods and
protocols) for the transmission of information via radio, typically radio-
frequency technology used instead of wired connections, making the systems
particularly exible.
ZigBee™
Zigbee™ is a set of specications based on the IEEE-802.15.4 standard for
the creation of Wireless Personal Area Networks (WPAN). Comparable in
some ways to Bluetooth, it stands out for its very low power consumption
and the reduced cost of implementation, despite having a maximum data
transfer speed of 250 kbit/s. ZigBee™ devices, with compact dimensions and
low costs, are designed to work in dedicated self-organised networks (Mesh
networks) and are used in many elds.
1.4 Advantages of the wireless system
Advantages of a wireless network over a wired network
• Mobility of sensors;
• Easy to install and connect the devices;
• Coverage even where obstacles are present;
• Flexibility in the event of structural modications;
• Reduction in wiring costs;
• Robustness.
The advantages of wireless networks can overcome some of the intrinsic limits
in wired systems. Typical network infrastructure features a wired backbone
with wireless access.
Advantages of ZigBee™
• Standard technology;
• Reduced costs;
• Can be used globally;
• Reliable;
• Supports a large number of nodes;
• Easy conguration;
• Long battery life;
• Secure data transmission.

The band centred around 2.45 GHz (used in the wireless sensor system for
refrigeration) is the only one that can be used all over the world, without
needing to apply for special licenses. In addition, the ISM band (Industrial,
Scientic and Medical) exploits the full potential of the standard, that is,
can use 16 transmission channels with a bit rate of 250 kbit/s.
Types of nodes
ZigBee™ Access Point - Co-ordinator and Gateway;
- Must be available and on in every network
- Coordinates the creation of the network;
ZigBee™ Router;
- Participates in the delivery of the messages, and must always be on;
- Available in Router-Bridge version for extending a wired local network
(for a list of approved controllers, see chapter on the features of the
Router), and EP1 Router-Sensor version.
ZigBee™ End-Device (sensors);
- Node with limited wireless functions;
- Low power consumption;
- Low cost;
For data communication with the Access Point, the end device uses a“parent”
for eective wireless transmission; this may be a Router or the Access Point
itself.

Example of a Mesh network
The MESH layout, used in the wireless sensor system for refrigeration between
coordinator nodes (access points) and router-bridge devices, ensures a high
tolerance to faults, as if one sensor loses wireless communication, the radio
signal still manages to nd an alternative route to reach the destination.

1.7 Using the Router
When does the Router need to be installed?
The Router is required whenever a direct connection is not possible between
the Access Point and the Sensor; this may occur when:
• The distance between Access Point and Sensor is greater than 30 m MAX
with visibility between the instruments.
• There is no visibility between the Access Point and the Sensor, and/or
there is shielding infrastructure that reduces the wireless communication
distance.
• In addition, the Router is required if the number of Sensors managed
exceeds 30 devices.
In addition, this is used to improve the reliability of the wireless connection,
the Router network can in fact nd an alternative path if one of the direct
connections between the sensors and the access point fails.
Recommended:
Up to 15 sensors 1 Router;
from 16 to 30 sensors 2 Routers;
from 31 to 45 sensors 3 Routers;
from 46 to 60 sensors 4 Routers.
1.8 General notes
The radio range of the devices is around a hundred metres in an open eld,
that is, without any obstacles.
In a closed eld the range varies signicantly based on the type of environment
and the surrounding objects (shelves, furniture, metal walls etc.).
Thick partition walls or reinforced ceilings and oors may represent impassable
obstacles.
The ideal position of the devices, especially the routers, often cannot be
dened theoretically but must be found by trial and error in the actual
installation.
Serial address assignment is valid for all devices
Make sure not to assign the same serial address ID to two devices in the same
wireless network.

The battery life is purely indicative and depends on the cycle transmission
time set and the quality of the wireless connection. If the device does not
communicate correctly with the Access Point (distance or interference
problems) battery life will be reduced due to the continuous attempts to
restore connection to the Access Point/Router.

2. BP SE SENSOR BUILTIN PROBE
The BP SE Sensor is designed to be positioned directly inside the showcases, tted using its own fastening bracket. The rear features
metal shielding that, combined with the thermal insulation inside the shell, prevents the formation of frost at the rear of the sensor,
and consequently better thermal insulation from the wall.
Fig. 2.a
2.1 Functions implemented and supervisor
variables available
• Instant temperature measurement performed every minute.
• Measurement ltering with weighted average based on parameter setting
for product temperature simulation.
• Data transmission at settable intervals, in minutes (the parameter aects
battery life).
• Monitoring of temperature thresholds for high temperature (HACCP) or low
temperature (product freezing) alarm signals.
• Automatic mode with preset parameters according to the showcase/
display case (normal, low temperature or open shelf).
• Local mode for Clean showcase status signal. Activating the Clean button
disables the high temperature alarms.
• TimeStamp for recording the instant measurement, expressed in hh:mm.
• Battery level in mV and residual charge in mAh.
• Wireless signal level in dBm +100 (less than 8=low, 15-30=medium, higher
than 30=excellent);
• Temperature alarm status related to the high and low thresholds.
2.2 Sensor conguration
The sensor is supplied with the address ID set to 127 and cannot be used with
the default ID; the range of available addresses is from 16 to 126. To assign the
ID use the rTM SE handheld accessory. For details on the address assignment
procedure see the instructions in the chapter on the rTM SE handheld further
on.
In emergency situations a new ID can be assigned (limited to the range from
16 to 99) using a magnet (e.g. magnetic screwdriver Carel code 0000000722),
as follows:
1. Position the magnet on SW1, holding it in position when the green LED
comes on;
2. The following will be shown in sequence:
- Green LED ON for 2 to 3s then OFF for 3 to 4s;
- Orange LED ON for 3 to 4s;
- Remove the magnet when the LED switches o;
- After a few moments the LED comes on yellow for 1s. This indicates
that programming procedure is active (if no actions are performed,
programming mode ends after 4/5 s, indicated by a double yellow ash,
leaving all the settings unchanged);
3. Move the Clean switch SW2 up and down a number of times equal to the
tens of the serial address being set (e.g. 10, once – 50, ve times). Each
time switch SW2 is moved up the red LED comes on for 1 s, (conrming
stimulation);
4. Subsequently use the magnet to stimulate switch SW1 a number of times
equal to the units (e.g. 1, once – 5, ve times). Each time the magnet moves
over the switch the green LED comes on for 1 s (conrming stimulation).
The order is not important (tens or units rst);
5. After 4/5 s the sensor exits the procedure, with the yellow LED ashing
twice (indicating the end of serial address setting mode);
6. Subsequently the sensor shows the serial address using a sequence of
ashes repeated cyclically three times. To read the codes, see the chapter
“Display sensor serial ID” further on.
7. Moving switch SW2 up interrupts the cycle;
The sensor address has been set and it’s ready to be bound to an Access Point.
The procedure can be performed before or after binding to the Access Point.
Make sure not to assign duplicate serial addresses, also considering other
devices in the network. For further information and explanations on the
procedure, see the rTM SE system installation guide.
Binding procedure
Binding is a special procedure used to associate the sensors with the Access
Point. Once completed, the sensors will send the temperature data measure
wirelessly only to the Access Point dened as its parent. Following this, the
Access Point will forward the data to the Modbus® RTU RS485 serial network.
The binding procedure requires the activation of the Access Point wireless
network and activation of the conguration switch SW1 using a magnet (see
the gure), done by passing the special magnet over magnetic switch SW1
for a few seconds. The LEDs will come on in sequence: green (1s), yellow (4 to
5s), green (6 to 10s). If at the end of the sequence the red LED ashes briey (1
to 2s), binding with the Access Point has failed. If the operation is successful,
successively activating switch SW1 will start manual data transmission,
signalled by the green LED ashing quickly twice.
If the automatic or manual data transmission fails, the red LED will ash briey
after the green LED comes on.
After this operation the sensor will start sending data on the temperature
measured, in the time interval set by parameter. Check that the LED comes on
for a few seconds at regular intervals, based on the transmission time set for
parameter (HR_01 TRANS_CYCLE). When the operation has ended close the
wireless network on the Access Point. The wireless network can be opened
and closed using the rTM SE handheld accessory.
Display sensor serial ID
To check the sensor serial address, proceed as follows:
• Move switch SW2 (CLEAN) up, stimulate SW1;
• The LED starts ashing in sequence. Count the number of the ashes to
calculate the hundreds (Yellow), tens (Green) and units (Red). Removing
the magnet or lowering the button exits the display probe serial address
procedure.
• Move switch SW2 back down.

Tab. 2.b
Resetting the sensor (maintaining the serial address)
The reset procedure is required when the sensor needs to be moved and
associated with another wireless network (dierent Access Point). This
operation may be required to recongure the sensor in a dierent wireless
network. The value of the serial address remains the same, and after a new
binding operation the sensor is reactivated in the wireless network. To reset
the sensor, proceed as follows:
1. Place the magnet near magnetic switch SW1 (the green LED will come on);
2. Hold the magnet in place until the green LED goes o and the yellow LED
comes on (after approx. 6 to 10 sec.);
3. When the yellow LED comes on, move the magnet immediately away
from the sensor and check that the LED ashes quickly before going o
(RESET COMPLETE).
To check that the sensor has been reset, proceed as follows:
1. Make sure the Access Point wireless network is closed (L1 ashing slowly
1s);
2. Stimulate switch SW1 on the sensor with the magnet;
3. Check that LEDs come on in the following sequence:
- green LED (1 s);
- yellow LED (4 to 5 s);
- green LED (15 s);
- red LED (1 s);
Make sure that there are no sensors with the same serial address in the new
network. If this is the case, assign a new serial address.

RESET sensor and assign default serial address (=127)
To restore the sensor serial address to the default value, proceed as follows:
1. Place the magnet near magnetic switch SW1, the green LED will come on.
2. Hold the magnet in position until the green LED goes o and the yellow
LED comes on (after approx. 6 to 10 s);
3. Immediately remove the magnet from the sensor and at the same time
move the CLEAN switch (SW2) up, making sure the yellow LED ashes a
few times.
4. Move the CLEAN switch to the OFF position and make sure the yellow LED
completes a rapid sequence of ashes (RESET COMPLETE);
Otherwise repeat the procedure.
To check that the sensor has eectively been reset, proceed as follows:
1. Make sure the Access Point wireless network is closed (L1 ashing slowly
1 s);
2. Stimulate the switch SW1 with the magnet;
3. Check that LEDs come on in the following sequence:
- green LED (1 sec.);
- yellow LED (4 to 5 sec.);
- green LED (15 sec.);
- red LED (1 sec.);
Completing the reset procedure and assigning the default serial address
returns the sensors to the same status as a new device.
To assign a new address, repeat the serial address assignment procedure.
Note:
1. The sensor can only be reset if it has already been bound to an Access
Point.
2. Note that, after resetting the sensor, the number of devices set for the Access
Point remains unchanged. Realignment will occur after a maximum of around
2 hours.

Note: the LED is two-colour, red and green, which becomes yellow when both
LEDs are on at the same time. There may be dierent shades of yellow due to
dierent tolerance in the brightness of the red and green LEDs.
2.3 Sensor activation
When the sensor is put in SLEEP mode using the rTM SE handheld during
the procedure to assign the serial address (no transmission-minimum power
consumption), the sensor is eectively in standby; nothing is transmitted
until movement of the CLEAN switch is activated (sleep status). Activation is
not reversible, and the sensor will send the temperature measured every 16
min (default value) if the Access Point that the sensor has been bound to is
switched on.
To exit sleep mode, proceed as follows:
• Power up the Access Point;
• Move the CLEAN switch to the ON position (SW2);
• Make sure the red LED comes on for a few seconds.;
• When the red LED comes on immediately the CLEAN switch to the OFF
position;
• The LED on the sensor remains on until it has connected to the Access Point.
If the operation fails, the sensor returns to sleep mode, if however it’s successful
normal operation will resume, with data being sent every 16 min.
Check operation by stimulating the sensor.
Resetting the sensor in sleep mode
If the sensor needs to be reset when in sleep mode (Access Point network
parameters forgotten), proceed as follows:
• Move the CLEAN switch to the ON position (SW2);
• Wait for the red LED to come on;
• Stimulate SW1 continuously while the red LED remains on.
• Keep SW1 stimulated until the LED ashes (yellow) ;
• Remove the magnet from SW1 and move switch SW2 back down.
• Reset completed.

Parameters and functions
The BP wireless sensor reads the temperature and manages the associated
alarms at one minute intervals.
The data is then transmitted at the intervals set by parameter, according to the
application and the expected battery life. The sensors work most of the time in
low power mode, so as to save battery power. They are activated to make the
measurements and send the data at the preset time.
Activate switch SW1 to send the sensor data manually, or check the connection.
The CLEAN button is used to set cleaning status or deactivate the showcase,
thus disabling the high temperature alarms.
When returning from CLEAN mode, the high temperature alarms are disabled
for a time equivalent to the auto-conguration cycle (AUTO_DELAY).

15
ENG
“Wireless probes”+0300030EN - rel. 1.0 - 16.07.2010
The sensor takes individual instant temperature measurements, however can
also provide a weighted average, used to better approximate the product
temperature. The logic for the alarms and all the other functions depends on
the instant temperature measurement.
Wireless communication is activated automatically in the following situations:
• moving the CLEAN mode switch (SW2);
• stimulating the magnetic switch (SW1).
In all other cases, data transmission is dened by the set transmission cycle.
Note:
• The temperature measurement, with the update of the instant and average
values, is performed at 1 minute intervals.
Important: the value is displayed on the supervisor after the set sensor
transmission time .
The average temperature value is calculated using the following formula:
Temp_AVG = (Temp_AVG-1 * (M - 1) + Temp_Ist) / M
Where:
• Temp_AVG-1 Previous average temperature value
• Temp_Ist Instant temperature measurement
• M Average weight (= AVERAGE_PARAM)
The average function also introduces an average measurement delay with a
time constant equal to the average weight value (in minutes).

• When the threshold is exceeded, the alarm is signalled only if this persists
for a time greater than the delay set;
• If the temperature returns within the threshold before the delay time, the
accumulated count is reset;
• The alarm is reset instantly when the temperature returns within the
threshold.

Automatic conguration procedure
The automatic recognition procedure is used to recognise the type of
showcase and consequently congure the parameters for the showcase
that the sensor is installed on. The automatic recognition cycle is activated (if
enabled by EN_AUTO_CONF):
• When the temperature falls below the threshold MODE_AUTO_TRESH;
• When returning from CLEAN mode, closing the switch;
• When a previous cycle is completed.
When the AUTO_DELAY time has elapsed, if the following conditions are true:
• Final temperature rise less than 1°C/h;
• Final temperature within a xed band of temperatures for the various types
of showcase:
- medium temp. showcases = from -2°C to + 6°C
- low temp. showcases = less than -10°C.
The MODE_PARAM parameter is given the new value corresponding to the
type of showcase and the associated values for the alarm thresholds, alarm
delay and average weight are loaded;
Note:
• In the event of increases in temperature for low temperature showcases,
the recognition procedure is disabled for 3 times the value of AUTO_DELAY,
to avoid false recognitions.
• The temperature alarms are always enabled, if MODE_PARAM and
consequently the associated parameters are changed, the alarm logic
depends on the new parameters.
• The parameters associated with each mode (0-3) are saved separately and
permanently, and are loaded automatically when the mode is changed.
• The values of the parameters associated with the mode must be set (by the
supervisor) making sure that MODE_PARAM does not change, otherwise
the values transferred may be ignored.

3. EP SE, SA, SI SENSORS AND CI PULSE COUNTER
3.1 Parameters and functions
The wireless devices read the temperature and manage the associated
alarms at intervals set by the transmission time parameter, according to
the application and the expected battery life. The sensors work most of the
time in low power mode, so as to save battery power. Press the button or
stimulate the magnetic switch to send the sensor data manually, or check the
connection.
3.2 Description of the acquisition process
The devices acquire all the values before sending their status to the Access Point.
Consequently, the device sampling interval is equal to the transmission time.
3.3 Device conguration
Select the desired network address using the 8 dipswitches (0=OFF; 1=ON) as
shown in the table. The possible sensor addresses are from 16 to 126.

3.4 Binding procedure
Binding is a special procedure used to associate the sensors with the Access
Point. Once completed, the sensors will send the temperature data measure
wirelessly only to the Access Point dened as its parent. Following this, the
Access Point will forward the data to the Modbus® RTU RS485 serial network.
Before performing this operation, make sure that the sensor serial address has
been set.
After having opened the domain on the Access Point (see the instructions in
the chapter on the Access Point), proceed as follows on the sensor:
Remove the protection from the contact on the battery to power up the
device;
Check that the LED comes on for a few seconds with brief ashes.
Press the button once or activate the magnetic switch. Pressing it again
activates a procedure to check the quality of the wireless signal (see the
chapter“Analysing wireless signal quality”);
LED L1 on the sensor remains on until connection to the Access Point is
complete, ashing for around 10s, then L1, L2 and L3 ash together for a few
seconds (wireless network connection).
The procedure for analysing wireless signal quality then starts for around 1
minute. The following come on in sequence:
1. L1 Indicates wireless transmission has occurred;
2. L1-L2 Indicates the signal has been received by the Access Point;
3. L3 ashes from 1 to 3 times, based on the quality of the wireless signal;
- 1 ash, wireless connection with minimum signal strength;
- 2 ashes, wireless connection with medium signal strength;
- 3 ashes, wireless connection with excellent signal strength;
Button T1 is connected in parallel with the magnetic switch. The case does not
need to be opened to stimulate the sensor for communication
Note: if LED L1 ashes once instead of remaining on, it means that the sensor
has already been bound to an Access Point. In this case, reset the sensor (see
Resetting the devices)
The Access Point shows that connection has been made by LED L3 coming
on for around 1s., even if another node in the network is sending a message.
Check the conguration: the sensor will be correctly bound if whenever the
button is pressed or the magnetic switch is activated, the LEDs come on for a
1 min sequence.
• L1, on for 1s;
• L1-L2, on for 1s;
• L3, ashes from 1 to 3 times, based on the quality of the wireless signal;
- 1 ash, wireless connection with minimum signal strength;
- 2 ashes, wireless connection with medium signal strength;
- 3 ashes, wireless connection with excellent signal strength;
For the EP SE Sensor, in normal operation LED L1 ashes for 1s every 20s. In
general, for the other devices, the LED comes on whenever data is sent, and
consequently based on the device transmission time.
Important: the sensor binding operation may fail if:
- the distances are high and/or there is infrastructure that does not allow
communication between the devices (see the example of sensor S2 in Figure
4.c);
- the maximum limit of sensors allowed for the Access Point has been reached
(max 30). In this case, an additional Router-Bridge is needed for up to a
maximum of 60 sensors.
3.5 Resetting the sensor (unbinding)
The reset procedure is required when the sensor needs to be moved and
associated with another wireless network (dierent Access Point). This
operation may be required to recongure the sensor in a dierent wireless
network. The value of the serial address remains the same, unless the
conguration dipswitches are moved. After a new binding operation the
sensor is reactivated in the wireless network. To reset the EP SE Sensor, proceed
as follows:
1. Remove the battery (press the button to discharge any residual energy in
the circuit) and replace the battery in its socket (LEDs L1, L2, L3 come on
at the same time, then ash quickly and switch o).
2. Immediately after the LED have switched o (within a few seconds) press
button T1 until the pairs of LEDs L1-L3 and L2 ash alternately.
3. Release the button. LEDs L1, L2, L3 will ash briey and then switch o.
To make sure the sensor has eectively been reset:
1. Make sure the Access Point wireless network is closed (L1 ashes slowly
1s).
2. Press button T1 on the sensor and make sure LED L1 comes on and
remains on for around 20 sec.
WARNING: The sensor has been unbound (reset) and maintains the same
network address assigned.
To change the address, remove the battery, move dipswitches 1 to 8, and
replace the battery.
Note:
1. The sensor can only be reset if it has already been associated with an
Access Point;
2. Resetting the sensor does not delete the space reserved inside the Access
Point, which will continue to maintain the data saved inside. Note that,
after resetting the sensor, the number of devices set for the Access Point
remains unchanged. Realignment will occur after a maximum of around
2 hours.
Important: pay careful attention to avoid duplicate assignment of network
serial addresses, so as to avoid overlapping temperature values.
The sensor is supplied with the battery already tted, and with the positive
pole insulated by a protective lm; this must be removed after assigning the
network serial address.
3.6 General warnings
When replacing the battery, strictly observe the following instructions.
The battery may explode if replaced with another of an incorrect type. Dispose
of the used batteries according to the standards in force;
Install the sensor with the cable gland facing downwards;
Replacing the battery
Remove the cover, remove the battery, and replace with another of the same
type. Close the cover again.
Rules for disposing of the battery

4. EP SENSOR EXTERNAL PROBE
The EP SE Sensor is designed to be tted inside showcases or cold rooms, and can house two external passive NTC temperature probes
10K@25°C (Beta(25/85) = 3435K) and two digital inputs to be used to monitor door and defrost status, or used as generic inputs.
Fig. 4.a
4.1 Functions implemented
• Instant temperature measurement performed every minute, probe 1;
• Instant temperature measurement performed every minute, probe 2;
• Data transmission at a settable interval in minutes (this aects battery life);
• Monitoring of temperature thresholds for high temperature (HACCP) or low
temperature (product freezing) alarm signals.
Main variables available to the supervisory system
• Probe 1 temperature;
• Probe 2 temperature;
• Battery level in mV ;
• Wireless signal level in dBm +100 (8 = low signal, 15 to 30 = medium signal,
greater than 30 excellent).
• Temperature alarm status related to the high and low thresholds.
• Data transmission interval;
• Enable high temperature alarm;
• TimeStamp for recording the instant measurement, expressed in hh:mm;
4.2 Parameters and functions
The EP SE wireless sensors read the temperature and manage the associated
alarms at intervals set by the transmission time parameter, according to the
application and the expected battery life. The sensors work most of the time in
low power mode, so as to save battery power. Press the button on the sensor
to send the sensor data manually, or check the connection.
The main parameters and functions of the sensor are:
-Data transmission activation:
-Wireless transmission is activated in the following conditions:
• Change in status of the digital inputs, door and defrost;
• Change in status of the digital inputs, door and defrost;
• Temperature probe fault alarms;
• Briey pressing the button.
In all other cases, data transmission is dened by the set transmission time.
Logical state of DOOR_POL and DEFROST_POL variables
The following table shows the logical state of the input based on the electrical
state of the contact (open or closed).

Fig. 4.a
The gure shows the high temperature alarm function:
1. when the threshold is exceeded, the alarm is signalled only if this persists
for a time greater than the delay set;
2. if the temperature returns within the threshold before the delay time, the
accumulated count is reset;
3. the alarm is reset instantly when the temperature returns within the threshold.
Enabling and disabling the digital inputs
Management of the door and defrost inputs can be enabled or disabled using
EN_DI_DOOR for the door input and EN_DI_DEFROST for the defrost input.
If not enabled, the inputs are inactive (0). Even when disabled, however, the
logical state of the digital inputs can be identied by reading the value of
IN_1_STATUS for IN_1 (1=Active, 0=Not active) and IN_2_STATUS for input IN_2
(1=Active, 0=Not active). By default the door and defrost inputs are enabled.
The high temperature alarm is activated after the delay if the door input is
active. For correct operation of the temperature alarm signals, the status of the
door and defrost must always be read as inactive, even if the two inputs are
not used. To return both to normal conditions, the value of the two polarity
states can be set to 1 for the door (DOOR_POL) and defrost (DEFROST_POL), or
alternatively the two inputs can be jumpered if not used.
Enable and disabling the analogue inputs
EN_NTC_1 and EN_NTC_2 enable and disable the probe inputs. The probe
inputs can be enabled and disabled using parameters EN_NTC_1 and EN_
NTC_2 respectively. If a probe input is disabled, the temperature reading is
equal to 0°C; in this event, the probe alarm fault is not managed and remains
constantly inactive (0). By default the probe inputs are enabled.
