Environmental policy
• Never dispose of this equipment with household waste. Electrical and electronic
products contain substances that can be harmful to the environment if not
properly handled. The crossed-out waste bin symbol indicates separate collection
of electrical devices, which must be separated from other urban waste. For correct
environmental management, at the end of its useful life the equipment should be
taken to the collection centers provided for this purpose.
• The parts that make it up can be recycled. Therefore, please respect the regulations
in force regarding environmental protection.
• If you replace the equipment, the original equipment must be returned to your
dealer or deposited at a specialized collection center.
• Violations are subject to the penalties and measures stipulated in environmental
protection law.

8
• The system must be installed by a qualified technician.
• This product must not be modified or disassembled under any circumstances.
• Do not handle the system with wet or damp hands.
• In the case of any malfunction of this appliance, do not repair it yourself. Contact the
sales distributor or service dealer for repair or disposal of the product.
• Check that the HVAC installation has been installed according to the manufacturer's
requirements, complies with local regulations in force and is working correctly
before you install the Airzone system.
• Place and connect the elements in your installation in accordance with current
regulations covering electrical installations.
• All connections must be made with the power supply completely turned off.
• Take care not to short circuit any of the system's connections.
• Please refer carefully to the wiring diagram and these instructions when wiring.
• Connect all wiring securely. Loose wiring may cause overheating at the connection
points and is a possible fire hazard.
• Do not locate the Airzone communication bus close to power lines, fluorescent
lights, actuators, etc. as this may cause interference in communications.
• The connection to the external power supply must include a main switch or other
method of disconnection that includes a constant separation for all polarities,
in accordance with appropriate local and national regulations. The system will
Before Starting
automatically restart if the power supply is turned off. Use separate circuits for the
unit that is to be controlled and the power supply to the system.
• Check the polarity of each device's connectors. A wrong connection can seriously
damage the product.
• To connect to the system, use Airzone cable: four-wire cable (2x0.22 mm2twisted
shielded wires for data communications and 2x0.5mm2wires for power supply).
• A Blueface Zero thermostat must be used to enable all the Airzone system
functionalities.
• Recommendations for the placing of the thermostats:
• For equipment using R32 refrigerant, verify the compliance with the local
refrigerant regulation.
• The room size installation requirements mentioned in the manual of the ducted
indoor unit, to which the Easyzone is connected, remain applicable to each and
every separate room served by the Airzone unit.
• Ducts connected to Easyzone shall not contain a potential ignition source.

AI
Allows the return temperature of an AC unit to be measured by means of an external probe.
The use of this probe is recommended when working with electromechanical or NON Inverter
units, where the return temperature of the AC unit must be controlled.
To connect the Airzone connection bus, there is one 4-pin
terminals. This system allows star and bus connection. Use
2x0.5+2x0.22mm2Airzone cable. Fix the cables with the screws
on the terminal, following the color code.
The Airzone connection bus is used to connect all the internal elements independent of the
main control board and can control up to 8 zones.
To connect the CAN bus, there is one 5-pin terminal. Use 2x0.5+2x0.22mm2Airzone cable. Fix
the cables with the screws on the terminal, following the color code.
CAN
The CAN bus allows connecting the different modules of the system with the main control
board, enabling communication between them.
The system main control board has wireless communication for connecting wireless Airzone
elements. These devices are associated by opening the association channel on the main control
board. To do this, make a short press on the button next to the icon; when LED stays red
it means that the radio channel is open. For 15 minutes, the system will keep the wireless
association channel open.

11
The automation bus allows several systems to be interconnected in order to manage all of
them, using the control peripherals offered by Airzone or their integration into a higher-level
control network.
To connect the automation bus, there is one 5-pin terminal.
This system only uses bus connections. Fix the cables with the
screws on the terminal, following the color code.
O2
This output can be configured as "Low temperature circuit demand" (underfloor heating)
(default) or as "Manual" (see Advanced settings section on the Blueface Zero thermostat 
System parameters).
• Configuration Low temperature circuit demand: The output must be configured as
"Underfloor radiant water"* type (default).

*If the output is configured as "Electric radiant" type, the relay will not be activated.
The technical characteristics of the O2 relays are Imax 1A at 24-48 V voltage free. To control
higher power elements, the use of contactors of the power to be controlled is recommended.

12
This connector supplies power to the system main control board and consequently to the
elements connected to it. External power supply at 110/230VAC. The power connection to the
module is via a 3-pin terminal. Fix the cables with the screws on the terminal, following the
color code.
The connection to the external power supply must include a main switch or other
method of disconnection that includes a constant separation for all polarities,
in accordance with appropriate local and national regulations. The system will
automatically restart if the power supply is turned off. Use separate circuits for the
unit that is to be controlled and the power supply to the system.
O1
This output can be configured as "High temperature circuit demand" (Radiator) (default)
or as "Manual" (see Advanced settings section on the Blueface Zero thermostat System
parameters).
• Configuration High temperature circuit demand: The output must be configured as
"Radiator/Ceiling water"* type (default).

AIRZONE CONTROL MODULE FOR WIRELESS VALVES VALR
(AZCE8CM1VALR)
Assembly
Connection
Connect the AZCE8CM1VALR module to the CAN bus of the main control board. For this
purpose, there is one 5-pin terminal. Use 2x0.5+2x0.22mm2Airzone cable. Fix the cables with
the screws on the terminal, following the color code.
For further information, see the technical datasheet.
This module is mounted on DIN rail. It should
be placed and mounted in accordance with the
current electrotechnical regulations.
Note: To remove the module on DIN rail, pull the
tab downwards to release it.
Reset
If you want to return to factory values, press and hold the association button until LED
change to searching status (blue). Wait for the LEDS to go back to their normal state before
starting with the initial configuration process.

Note: To remove the module on DIN rail, pull the tab downwards to release it.

16
Configuration
Control Z1-Z8 relay specs: Imax = 5 A at 110/250 Vac.
Note that to control elements with a greater power, it is recommended to use contactors in
accordance with the power required. Remember to connect the neutral connector directly
from the circuit to the element to be controlled.
Important: According to the current local and national regulations, it is mandatory to add
a switch (or other element to disconnect the system) to the external supply wiring so that a
constant separation between poles is guaranteed. The system will restart automatically if the
supply is eventually turned off.
Configure the AZCE8CM1VALC module according to your installation. To do this you must leave
the LED that corresponds to your installation on:
1. Press the operation relays configuration button for 2 s.
2. Switch between the different configurations by
pressing the same button.
3. Save the configuration by another 2 s pressing in the
same button.
