up to installation and maintenance.
For further details and technical information see the rTM SE user manual
(code +0300030IT).
The following steps are recommended for correct installation of the rTM
SE system:
- site inspection;
- selection of the devices, installation plan and quotation;
- system configuration;
- installation;
- commissioning.
1. INTRODUCTION
2. SYSTEM COMPOSITION
The rTM SE system is made up of devices that provide the ZigBee™
wireless infrastructure, i.e. Access Points, Routers, Bridges and other
components with specific functions, such as sensors, actuators, counters
electricity meters, and so on. To identify the best components for the
design requirements from those described below, the following aspects
need to be considered:
• what needs to be measured, monitored and controlled;
• intensity of use (choice between battery or mains powered devices);
• installation site (accessibility to the point of measurement, obstacles
blocking the wireless signal).
rTM SE system wireless sensors
• BP SE sensor code WS01U01M00 (powered by long life battery)
– 1 Temperature (built-in probe)
– IP65 sealed case, no wiring required.
– Suggested application: showcases, HACCP procedures.
• EP SE sensor code WS01W02M00 (powered by long life battery)
– 2 Temperatures
– 2 digital inputs
– The temperature values are measured by CAREL NTC probes
(supplied separately).
– The digital inputs can monitor defrost status, door open, light on,
external alarm etc. (wiring to voltage-free contacts needed).
– Suggested application: cold rooms, refrigerated cabinets etc.
• SA room sensor code WS01G01M00 (powered by long life battery)
– Room temperature and humidity
– Wall-mounted, appearance suitable for residential uses. No wiring
required.
• SI sensor for industrial environments code WS01F01M00 (powered by
long life battery)
– Room temperature, humidity and light sensor
– Wall-mounted, appearance suitable for residential uses. No wiring
required.
rTM SE system ZigBee™ wireless structure
• Access Point: ZigBee™ wireless receiver / transmitter
– code WS01AB2M20 (powered at 12 Vac/dc).
– This is the connection point between the rTM SE system wireless
components and the wired data line to a Carel supervisor or BMS
(Building Management System), with Modbus® protocol over RS485.
– Each device in the rTM SE system is, during configuration, assigned
to a specific Access Point and consequently to a specific wireless
network.
– Up to 7 Access Points can be connected to each serial line.
Below is a detailed description of the operations that must be carried out
for correct maintenance.
Important: configuration and installation of the rTM SE system
must be performed by qualified personnel. Prior training at CAREL is
suggested.
• Router: ZigBee™ wireless repeater
– code WS01RC1M20 (powered at 230 Vac).
– Repeating the wireless signals means:
– larger surfaces and greater distances can be covered between
Access Point and sensors;
– obstacles or unfavourable conditions for wireless coverage can be
overcome;
– the network of sensors can be extended to include a greater number
of units.
Other rTM SE devices with Router function incorporated
The rTM SE system also allows other devices, fitted with external power
supply, to act as wireless repeaters, incorporating the Router function.
– EP1 router sensor code WS01VB2M10 (powered at 12/24 Vac/dc).
– Same functions as the EP SE sensor, integrating the Router function.
– 2 NTC temperature probes, 2 digital inputs (see EP SE sensor).
– The external power supply makes it useful for applications that
require very frequent transmissions (fast switching cycles of the
digital inputs that require wireless transmission), e.g.: CAREL“wireless
floating suction” system to reduce power consumption, adapting
the operation of the compressor rack to the load.
• Router-Bridge code WS01RB2M20 (powered at 12/24 Vac/dc)
– Completely transparently replaces a section of RS485 cable using
ZigBee™ wireless transmission between Router-Bridge and Access
Point. For the communication limits see the technical manual.
– A Router-Bridge can be connected to generic Modbus devices wired
to the Router-Bridge RS485 sub-network.
– These devices, physically connected to the Router-Bridge only, are
thus “detected” by the CAREL supervisor or the BMS as if they were
physically connected to the same RS485 network as the Access Point.
– Suggested application: Modbus® systems where it is difficult or too
costly to install sections of RS485 serial cables
• RA router-actuator code WS01H02M20 (powered at 12 Vac)
– This is an I/O expansion module with 2 relay outputs, 2 digital inputs
and 1 input for NTC temperature probe (10K@25°C). It includes a
configurable heating/cooling thermostat function.
– There are numerous applications for this device, which adds controls
and actuators to any position in the space covered by the rTM SE
wireless system.
• Code WS01E02M00 rTM SE CI WIRELESS COUNTERS (powered by long
life battery)
– Suitable for measuring power consumption or volume flows (gas,
water etc.) based on pulse signals generated by standard devices.
Can be used with any Modbus® system connected to the associated
Access Point.
– 2 pulse counter digital inputs
– 2 NTC temperature inputs (10K@25°C)

3. PREINSTALLATION
3.1 Site inspection
It is recommended to inspect the site where the rTM SE system devices will be installed, so as to have a clear overview and avoid any critical situations that
cannot be seen from photos or layout drawings and that may compromise correct operation. In this way, critical areas can be avoided due to interference
caused by other devices in the area or building structures that hinder wireless communication.
Complete the inspection keeping in mind the following points:
1. request or make a drawing (where possible to scale) indicating the layout of the showcases and cold rooms;
2. note the following information on the drawing:
– construction and thickness of inside walls;
– position of metallic obstacles in the environment: shelves, lifts, metallic partitions, fire doors;
3. check which other wireless devices are installed and their operating frequency;
4. check the traffic on 2.4 GHz wireless channels using a device that analyses the radio spectrum of 2.4 GHz channels. The CAREL rTM SE handheld code
WS01L01M00, can be used for this function; this device indicates the level of saturation on the wireless channel. To perform the operations with this
device, the following operations must be performed in sequence using the rTM SE handheld:
– switch the device on ON button;
– run the “Ener.Scan” function and confirm by selecting the right button. Wait for the end of the process;
– use the “up” and “down”buttons to scroll the values for all the channels.
The entire process lasts approximately one minute.

Note: Each installer and maintenance technician should have their own rTM SE handheld.
5. Check which channels are less occupied (i.e. 17 and 19 in the example shown). The ZigBee™ system is designed to share radio band with other devices
that operate on the same channel. Using a very busy channel will however reduce performance, causing a decline in speed and response time.
6. Note the information found using the rTM SE handheld on a specific document, or enclose a photo of the display that shows all the channels. It is
important to mark the position where the scan was performed on the layout.The outcome must be kept together with the installation data documents.
The data measured and the photo are useful in recognising any changes that may occur due to external causes (e.g. subsequent addition of other
ZigBee™ devices).
It is important to assign the system the best communication channel available when the system has been configured in advance in a different site (follow
the instructions shown below for the assigning the Access Point parameters).

8. if other wireless devices need to be installed, check their technical specifications to make sure they work at the same frequency (2.4 GHz) as the rTM SE
system (e.g. alarm system, inventory management devices, queue number systems, etc.).
3.2 Installation work
Have an electrician prepare the following, noting on the layout drawing:
• layout of the RS485 serial line between Access Point and supervisor;
• junction boxes installed for the Access Point, Router and other devices that require an external power supply, where the power transformers are also
located;
• supervisor connections:
– 230 Vac power supply;
– Ethernet network;
– phone line connection if a modem is used;
• drilling template to install the BP SE sensors on the showcases (to make installation faster).
3.3 Selecting the devices and quotation
1. On the layout drawing, position the Access Points, preferably:
– near the supervisory system, to limit the length of the serial line
– near the highest number of sensors possible, considering an operating radius of the wireless signal of 30 m;
2. define the position of the Routers on the drawing, so as to guarantee wireless coverage across the entire area where the sensors are installed. It is
important to consider that the environmental conditions may change. When positioning the devices, ensure that the wireless signal from each sensor
or Router can reach at least two other devices in the same wireless network, i.e. Access Point and Router, or two Routers;
3. check the layout of the store, considering that intermediate obstacles (fixed or moving) may block the signal. Install Routers to amplify and extent the
signal. Remember that each Access Point can directly manage 30 sensors, or 60 when adding a Router. The following guidelines should be observed:
– Up to 15 sensors: 1 Access Point and 1 Router;
– From 16 to 30 sensors: 1 Access Point and 2 Routers;
– From 31 to 45 sensors: 1 Access Point and 3 Routers;
– From 46 to 60 sensors: 1 Access Point and 4 Routers;
4. assign a progressive number to the Access Points (serial ID from 1 to 7) and the sensors (ID from 16 to 126). The Routers are configured automatically
assigning a progressive serial ID from 200 to 247, for a maximum total of 60 devices, 48 of which can be connected to the supervisor;
5. create an installation table, as shown in the following example, entering the same information and the serial ID references as on the installation drawing
and updating the layout drawing with the same references.
Then add the Router MAC field and serial ID, which will be assigned during configuration/installation. For EP SE sensors and EP1 Router-Sensors fitted with
two temperature probes, also write the number of the probe, NTC1 or NTC2, and the associated digital input.
Example of a table to be completed with the installation data.
The table provided at the end of this manual can be used.

6. After having completed the table and identified the numbers and models of the devices to be installed, complete the list of product codes required
to order the material.
7. Remember to also add the following codes to the order:
– Transformer, plug in version: TRASP3E120
– Electrical panel transformer: TRADR4W012
Use one transformer for each of the following components:

4. SYSTEM CONFIGURATION
When configuring the system directly on site, the Access Point can automatically select the best communication channel. On the other hand, for pre-
configuration away from the site the wireless channel identified during the site inspection must be chosen, and the Access Point configured using the
“Clone_AP”program. If the channel is already saturated by other existing systems, there may be a decline in communication performance between devices.
Considering the data transmission times of the rTM SE system, this problem is generally not significant.
Use the following procedures to complete the basic configuration of the system.
Subsequently the parameters are chosen and the corresponding Carel supervisory system (PlantVisorPRO or PlantWatchPRO) settings made.
4.1 Binding procedure
The binding procedure is a special operation used to bind the probes to the Access Point. Once completed, the Sensors and Routers will send the data
on the temperature measured wirelessly only to the one Access Point associated, over the wireless channel defined by assigning the network parameters.
The Access Point receives the data by the sensors and other devices and forwards them over the Modbus® RTU RS485 serial line to the supervisor.
4.2 Conguring the devices
The following operations must be performed on the devices:
• setting the serial address;
• binding.
4.3 Conguring the Access Point
To configure the Access Point follow the instructions shown below.

Assign the serial address with the local button to monitor the
energy meter parameters.
• Press the local button four separate times for no more than
a second, and no more than a second apart.
• This sequence accesses Modbus serial address
programming mode.
• This mode can only be activated if the Modbus address is
NOT already assigned.
• Accessing this mode is confirmed by a sequence of green-
red-yellow flashes of the LED for 1.5 seconds.
• After accessing this mode, the LED goes off and the device
waits for the button to be pressed; data entry is divided into
two stages, entering the tens and entering the units.
Setting the tens of the Modbus address
• The number of times the button is pressed during this stage
represents the tens of the new Modbus address.
• During this stage, pressing the button causes the LED to
flash red; the button must be pressed between 1 and 12
times.
• The first stage ends 3 seconds after the button was last
pressed.
• At the end of the first stage, the LED flashes green-red-
yellow to indicate the changeover from tens to units.
Setting the units of the Modbus address
• The number of times the button is pressed during this stage
represents the units of the new Modbus address.
• During this stage, pressing the button causes the LED to
flash green; the button must be pressed between 0 and 9
times.
• The second stage ends 3 seconds after the button was last
pressed.
• At the end of the second stage, the number entered is
verified; if within the allowed limits (values from 16 to 126
inclusive), the LED flashes green-red-yellow to confirm the
end of the setting procedure.
• If the value entered is not allowed, the device exits
programming mode and returns to the previous status,
without applying any further effect.
Important! Do not assign duplicate serial addres-
ses.

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, five times). Each
time switch SW2 is moved up the red LED comes on for 1 s, (confirming
stimulation);
4. subsequently (before exiting the programming procedure) use the
magnet to stimulate switch SW1 a number of times equal to the units
(e.g. 1, once – 5, five times). Each time the magnet moves over the switch
the green LED comes on for 1 s (confirming stimulation). The order is not
important (tens or units first);
5. after 4/5 s the sensor exits the procedure, with the yellow LED clashing
twice (indicating the end of serial address setting mode);
6. subsequently the sensor shows the serial address using a sequence of
flashes (repeated cyclically three times.
• red, the number of times indicates the tens;
• green, the number of times indicates the units;
7. count the flashes and check that the code corresponds to the address
assigned;
8. moving switch SW2 up interrupts the cycle, otherwise it’s repeated 3 times.
The procedure can be performed before or after binding to the Access Point.
For addresses from 100 to 126, the rTM
SE handheld must be used.
Important!
When entering programming mode,
there is a timeout of around 4-5 s.
Make sure not to assign duplicate
serial addresses, also considering other
models of sensors.
The MAC Address is also shown on the
product label.
Important!
With the setting the address ma-
nually, the sensor address can be set
before or after binding.
