INTRODUCTION
Compatibility
This documentation is compatible with the programs Roof Top and Aircoolair:
Ranges Baltic I, Baltic 410, Flexy I, Flexy II, FX,AC and LV, starting from the version 23.0
Important Warning
Any parameter modification should be carried out by trained and licensed competent
technician.
Before start-up or restart of a unit controlled by Climatic 50, it is mandatory to check adequacy between Climatic
50 and the unit with its options.
38xx menus for unit and options
39xx menus for communication
In case of wrong parameters, I/O links could be incorrect and may create some operation problems for the units
and ultimately breakdowns.
Lennox cannot be held responsible for any claims on the units due to a wrong parameters sequence or a
parameters modification carried out by non competent technicians. In this case, the warranty will be legally null and
void.
Any wiring modification on the CLIMATIC 50 must be done by Lennox technician or employees
having valid electrical qualification and authorisation.
For any modification of wiring on the 24V supply or on 4-20mA sensor, check the polarity prior to apply the
power. Wrong polarity may cause serious damage and destroy the Plan network. Lennox will not accept liability for
damage caused by wrong power connection or any wiring modification done by people without valid training and
qualifications.
Any external connection with the unit, using 24Vac voltage should not exceed a length of more than 30m. It
concerns external contacts connected to Climatic™50 logical inputs or humidifier control connection to the output
0-10v.
Over 30 m,the installer must interface this information with relays or converters or a external 24V supply.

WIRELESS
Function
The CAREL© / LENNOX© Wireless system is designed for all HVAC/R applications that require the monitoring of the
ambient conditions (temperature and for the future humidity) and/or the control of the ambient comfort based on the
requirements of the end user (operating mode, set point, …).
Description
Wireless is made up of:
• DCw (display):
An innovative wireless terminal with integrated sensors for measuring the temperature and humidity.
With the Climatic™ Roof-Top soft is it possible to have au maximum 1 DCw by unit.
• SCw (sensor):
Wireless sensors that measure the temperature and humidity.
With the Climatic™ Roof-Top soft is it possible to have au maximum 6 SCw by unit.
• APw (access point):
RS485/ZigBee™ gateway hat collects the information from the terminals and sensors.
With the Climatic™ Roof-Top soft is it possible to have au maximum 1 APw by unit.
• ARw (repeater):
ZigBee™ to ZigBee™ device that relays the wireless signals, allowing greater distances between the access point
and terminals or sensors
The Humidity management and the repeater are not currently available
Terminology
Wireless
Wireless means “without wires”, in contrast to the term “wired”.
Wireless network
Telecommunications system (series of devices, appliances, methods and protocols) for the transmission of information
via radio, typically radiofrequency technology used instead of wired connections, making the systems particularly flexible.
ZigBee™
Zigbee™ is a set of specifications 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 fields.
Advantages of the wireless solution
Advantages of a wireless network over a wired network
Mobility of the terminals;
Ease of installation and connection of the devices;
Coverage even where obstacles are present;
Flexibility in the event of structural modifications;
Reduction in wiring costs;
Scalability in the interconnection of terminals;
Sturdiness.
The advantages of wireless networks can overcome some of the intrinsic limits in wired systems.
Advantages of ZigBee™
Standard technology;
Reduced costs ;
Can be used globally;
Reliable;
Supports a large number of nodes;
Easy configuration;
Long battery life;

Secure data transmission.
The advantages of working at 2.4 GHz
The band centred around 2.45 GHz (used in the Wireless system) 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, Scientific and Medical) exploits the full
potential of the standard, that is, can use 16 transmission channels with a bit rate of 250 Kbit/s.

The Lennox© Wireless system is designed around an Access Point per unit. The latter, in a bubble radius of 50 meters
at most, allows connection to wireless displays 'DCw' and a maximum of 6 probes 'SCw'
The display allows the display and adjusting the parameters of the unit connected.
For probes, a setting can send to the unit concerned the average value of probes desired.
If the bus Master/Slave is made between units, the value of one or other probes connected to an APw may be sent to

INSTALLATION
Access point
APw
For this option the BM50 must be fitted on the Field-bus (or Analog Selection) port with the PCO100FD10 card (3 pins)
This card is used to interface a BM50 Field-bus with an RS485 type bus.
The card provides optically coupled isolation between the regulator and the RS485serial network.
If a board tLan, PCO100TLN0 (2 pins), is already present in the Field-Bus port, you need to replace it by a board RS485
(3 pins), PCO100FD10
Similarly, the BE50 is different depending on the type of bus, by default it is installed a BE50-tLan, PCOE00TLN0, in the
case of an option Wireless BE50-RS485 must be put in place, PCOE004850.
Fasten the APw to the wall with the cable gland facing downwards;
Tighten the antenna in the special housing (4), position it vertically to the floor;
Connect the ‘+’ and ‘-‘ of RS485 network to terminal (2);
Connect the power supply to terminal (1) ‘+’ from ‘G’ and ‘-‘ from ‘G0’.
General warnings
The APw must be positioned in the same open-space that the display DCw or probes SCw.
• Fasten the APw in the desired position, considering that as the device being installed is a radio device, the following
simple rules must be observed:
Avoid enclosing the appliance between two metal walls;
The efficiency of radio transmission is reduced when there are obstacles, metal shelving or other objects that may
block the reception of the wireless signals;
If the product is wall-mounted, fasten it to a masonry wall rather than a metal wall, to improve the range of the
signal;
Remember that the best position for the APw is one where it is “visible” to the other devices. It should be positioned
in such a way as to minimise any obstacles;
Like all radio equipment, avoid installing the APw near other electronic appliances, so as to avoid interference.
Do not install the instruments in environments with the following characteristics:
Strong vibrations or knocks;
Exposure to water sprays;
Exposure to direct sunlight or the elements in general;
If the appliance is used in a way that is not described by the manufacturer, the specified level of protection may be
affected.
Terminal and Sensor
DCw & SCw
The terminal and the sensor can be fastened to the wall using the support shown in the figure (included with the product).

Part A shown in the figure is used to lock the instrument to the support. A screwdriver will be required to remove the
instrument. This plastic part may be essential for hotel-type applications. For applications where the instrument needs to be
removed frequently (residential, office,…) part A can be eliminated simply.
CONFIGURATION
The following chapter describes the procedure for setting the address, configuring and connecting the devices for the
creation of a wireless domain connectable to the Climatic of the unit.
The procedure includes:
1. setting the address of the access point
2. setting the address of the terminals
3. setting the address of the sensors
4. Connecting the modes. In this phase, the terminals and the sensors are associated with the access point.
Visualization with the DS50
The Wireless option must be activated in the program Climatic ™ 50 by 3941 setpoint.
If a DCw must be installed; settle the 3942 setpoint by 1 (0 if not DCw)
The number of SCw installed must be setting in 3943 (between 0 and 6)
All other parameters of the option Wireless are visible on the special screens
To enable these special screens press the button 'Prg' when you're on the menu 000 or menus data 2xxx. Then you
move from one screen to another, press the buttons '↑' or '↓' to see the screen desired.
Setting the addresses
This is a fundamental phase in setting up the system, and allows each device to be identified uniquely.
Important: the address can only be set at this time. Any changes, when the channel has been set (see Automatically
search for wireless communication channel), will be ignored. The address can only be changed after having reinitialised the
device (see Resetting the devices).
Access point
APw
Position the dip-switch in the following manner:
No. 1 to Off
No. 2 to Off
No. 3 to Off
No. 4 to On
This configuration is at No. 8
Power up the access point;
Check that LED L1 (yellow) on the left is always on and the others are off. If the LEDs are not in this
status, reinitialise the access point (see Resetting the devices);

Automatically search for the wireless communication channel
The wireless system requires of use a transmission channel for the communication of the wireless messages between
the various devices. The best communication channel for the environment in question is automatically selected by the
access point, using the following procedure:
Power up the access point (the left LED must be on steady);
Press the button and check the activation sequence
For around 10 seconds
For around 20 seconds
The instrument is ready for the use.
The transmission channel has been selected and will be sent to the repeaters, sensors and terminals during the binding
phase.
Important:
• If the sequence is not as indicated, reinitialise the device
• If the instrument is reinitialised, all the instruments associated with it will be disconnected and will need to be connected
again.
