1.1 easy way ARIA
The easy way system is designed for all HVAC/R applications that require
the monitoring of the ambient conditions (temperature and humidity)
and/or the control of the ambient comfort based on the requirements
of the end user (operating mode, set point, …). These applications
may involve geothermal heat pumps and roof top units in hospitality,
residential and light commercial environments.
1.2 Description
easy way ARIA is made up of:
easy set:• an innovative wireless terminal with integrated sensors for
measuring the temperature and humidity.
easy read:• wireless sensors that measure the temperature and
humidity.
access point:• RS485/ZigBee™ gateway hat collects the information
from the terminals and sensors.
repeater:• ZigBee™ to ZigBee™ device that relays the wireless signals,
allowing greater distances between the access point and terminals/
sensors.

1.4 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 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.

General warnings
Fasten the access point/repeater 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 e ciency 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 access point 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 access point 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 speci ed level of protection may be a ected.
2.2 Terminal and Sensor
The terminal and the sensor can be fastened to the wall using the support
shown in the gure (included with the product).
Fig. 2.c
Fig. 2.d
Part A shown in the gure 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, o ce,…) part A
can be eliminated simply.

The following chapter describes an example of the procedure for setting
the address, con guring and connecting the devices for the creation of
a wireless domain connectable to a Master controller using the CAREL
protocol (pCO, PlantVisor, PlantWatch,…).
The procedure includes:
setting the address of the access point1.
setting the address of the terminals2.
setting the address of the sensors3.
connecting the modes. In this phase, the terminals and the sensors 4.
are associated with the access point.

1 Repeater (EW00RB2020) (if necessary)•
2 Terminals (EW00T*)•
2 Sensors (EW00S*)•
Fig. 3.a
3.2 Setting the addresses
This is a fundamental phase in setting up the system, and allows each
device to be identi ed 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
Power up the access point;•
check that LED L1 (yellow) on the left is always on and the others are •
o . If the LEDs are not in this status, reinitialise the access point (see
Resetting the devices);
Set the desired CAREL network address using the 4 dipswitches (0 = •
OFF; 1 = ON), as shown in the table.

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

3.4 Connecting the devices (Binding)
The logical connection between the access point and the wireless
terminals/sensors/repeaters is called binding. (see chapter 7 for the
possible ZigBee connections and levels).
The operation must be performed after setting the addresses.
Switch on the access point and check that the LED on the left is •
ashing.
OPEN DOMAIN: press the button and the 3 LEDs ash together.•
In this phase, new devices can be connected (see the following •
paragraphs).
CLOSE DOMAIN: After having connected all the devices, press the •
button to close the domain (the LED on the left starts ashing again).
Note:
the domain closes automatically 15 minutes after last opening.•
the domain can be opened/closed on the access point from the •
supervisor, using the following procedure::
OPEN DOMAIN: set I12 = 5266 and enable the command with D3 –
= 1.
CLOSE DOMAIN: set I12 = 5267 and enable the command with D3 –
= 1.
The variable D2 indicates the status of the network domain –
(0=closed; 1=open)

Terminal
After having opened the domain on the access point:
Access the parameters menu (see paragraph 4.5)•
Enter the password (22 default) for parameter loc 10.•
Set parameter loc12 to ON•
the terminal displays “bin” and subsequently•
“On” if the connection was successful –
“no” if the connection failed. –
Automatically exit the parameter programming menu.•
CHECK: On the rst valid transmission the terminal displays the •
“antenna” symbol.
The access point indicates that the connection has been made by •
sequentially activating the 3 LEDs .
Sensor
After having opened the domain on the access point:
Insert the battery, paying attention to the polarity. •
Check that LED (A) comes on for a few seconds.•
Press the button located on the rear of the sensor (B) once.•
The LED on the sensor (A) remains on until the device is connected to •
the access point.
Note: If the LED ashes once rather than remain on steady, it means
that it has already been associated with another access point. In
this case, reinitialise the sensor (see paragraph 3.5).
The access point indicates that the connection has been made by •
sequentially activating the 3 LEDs .
CHECK: The sensor will be correctly associated if each time the button •
is pressed once the LED ashes once.
Note: The binding operation on the terminal/sensor may fail if:
the distances are large and/or there is infrastructure that prevents •
communication between the devices (sensor S2 Fig. 3.e).
The maximum number of terminals/sensors connectable to the access •
point has been reached. In this case, a repeater will be required, to be
installed between the access point and the sensor.
The terminal/sensor is already connected to a network.•

Repeater
Connecting the repeater to the access point:
Power up the repeater.•
Open the domain on the access point (press the button once).•
Press the button on the repeater.•
All the LED should be on steady. •
The repeater is searching for an access point to connect to (all the LEDs •
ash every 20 s).
The binding operation is successful when only the yellow LED remains •
ashing.
Now the repeater is connected to the access point.•
Note:The binding operation between the repeater and the access
point may fail if:
the distances are large and/or there is infrastructure that prevents •
communication between the devices.
The maximum number of repeaters connectable to the access point •
has been reached.
Connecting sensor S2 to the system:
OPEN DOMAIN: press the button on the access point and the 3 LEDs •
ash together.
Wait 20s for the repeater/repeaters installed to receive the domain •
open message (all the LEDs ash).
In this status, new devices can be connected.•
Follow the sensor binding procedure (paragraph 3.4 sensor).•
CLOSE DOMAIN: After having connected all the devices, press the •
button to close the domain (the LED on the left starts ashing).
Note:
the domain closes automatically 15 minutes after last opening.•
No address needs to be set on the repeater.•
The setup is complete and the system is ready for data communication.
Note: each terminal/sensor should be visible from at least two
devices, either access point or repeater. In the event of a repeater
fault, in this way the terminal/sensor can nd an alternative route for
communicating with the access point.

3.6 Wireless variables
The variables that de ne the function of an END DEVICE in ZigBee
communication are as follows:
Minimum supervisor transmission time•
The devices (terminal and sensor), in order to ensure a battery life of at
least a few years, cannot transmit continually to the access point.
These devices are normally “sleeping” and “wake up” every ‘n’ minutes
(where ‘n’ is decided by the user based on the application).
Battery level:•
Indicates the current charge of the battery on the terminal/sensor. This
mainly depends on the time set between transmissions and the time
the keypad/display is used (terminal only).
In normal operating conditions, the following table shows the typical
battery life according to the time set between transmissions.
