PRECAUTIONS AND ENVIRONMENTAL POLICY
PRECAUTIONS
For your security, and to protect the devices, follow these instructions:
Do not manipulate the system with wet or damp hands.
Disconnect the power supply before making any connections.
Take care not to cause a short circuit in any of the system connections.
ENVIRONMENTAL POLICY
Do not dispose of this equipment in the household waste. Electrical and electronic
equipment contain substances that may damage the environment if they are not handled
appropriately. The symbol of a crossed-out waste bin indicates that electrical equipment
should be collected separately from other urban waste. For correct environmental
management, it must be taken to the collection centers provided for this purpose, at the end
of its useful life.
The equipment components may be recycled. Act in accordance with current regulations on
environmental protection.
If you replace it with other equipment, you must return it to the distributor or take it to a
specialized collection center.
Those breaking the law or by-laws will be subject to such fines and measures as are laid down
in environmental protection legislation.
GENERAL REQUIREMENTS
Strictly follow the directions outlined in this manual:
This system must be installed by a qualified technician.
Make all the connections with total absence of power.
Set and connect the elements in accordance with the electronic regulations in force.
In order to connect the elements of the system, use the cable: shielded twisted cable formed by 4 wires
(AWG 20 – 4 wired).
Do not connect the "-" pole in the "+" terminal. It may damage the device.
Do not place the system bus close to lines of force, fluorescent lights, motors, etc. It might cause interference on the
communications.
Follow these recommendations to locate the thermostats:
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.

INTRODUCTION
Airzone systems enable the management of Main and Zone interfaces. Main thermostats enable mode management or user
mode and fan speed of the system.
- Blueface Main: Mode, User mode icons shown in white color.
- Blueface Zone: Mode, User mode and Speed icons shown in gray color.
- Think Main: Accessing the settings menu, Operation mode and User mode are available.
- Think Zone: Accessing the settings menu, Operation mode and User mode are unavailable.
SYSTEM INSTALLATION
Before performing the Airzone system installation, check:
The equipment to control has been installed according to the manufacturer’s criteria and it works correctly without
the Airzone system.
In direct expansion unit systems, the indoor unit wired thermostat has been installed.
Important: For installations with radiant surfaces only, it is recommended the installation of buffer tanks.
In order to install properly your Airzone system, follow these steps:
Make all connections (see Section Connection).
- Connect all the elements of the system (thermostats, modules, etc.).
- Configure the microswitch of the relay radiant heat control module.
- Power the main control board.
Check all the assembly and the connection are correct (see section Assembly and connection evaluation).
Configure the system.
- Configure the secondary modules to associate them then to a main thermostat (see section Subordinate zones settings).
- Configure all the thermostats (see sections Initial setup and Advanced settings).
If you have any other doubt, check the user and installation manuals.
Access all our technical documents and the self-diagnosis section, check the most FAQs,
certificates, watch our videos and read our declaration of conformity at:

Don’t forget to download, complete and print the Commissioning document available on
myzone.airzoneusa.com to place it together with your installation.

CONNECTION
Important: Respect the color code for all the system elements.
1.- Connecting the zone and control modules of the system to the Airzone ZBS control board
Connect the zone modules of the system in any of the three Airzone connection bus terminals. Use the appropriate cable:
shielded twisted cable formed by 4 wires: 2x0.22 mm2 + 2x0.5mm2(AWG 20 – 4 wired). They must be connected by bus. For
added security, secure the wires using the turrets.
Note: For elements externally powered at 110 /230 Vac, for the communications, it is only necessary to connect the poles "A"
and "B" of the bus.
These are the elements that can be connected:
- Airzone ZBS wired/wireless intelligent round damper.
- Airzone ZBS wired/wireless only radiant zone module.
- Airzone ZBS wired/wireless zone module with xxx communication.
- Airzone ZBS relay radiant heat control module.
IMPORTANT: The maximum number of zone modules connected without their own power supply to the Airzone ZBS control
Board is: 6 zone modules connected to Blueface thermostats or 10 zone modules connected to Think or Lite thermostats. To
add more zone modules, it is necessary to install the supplementary power supply unit (Airzone ZBS additional 12V power
supply). Every supplementary power supply unit is enough for 6 or 10 modules as stated before.

2.- Connecting the thermostats
Connect each thermostat to the terminal corresponding to its zone module. Use the appropriate cable: shielded twisted cable
formed by 4 wires: 2x0.22 mm2 + 2x0.5mm2(AWG 20 – 4 wired).
In case of Wireless thermostat, check it has the battery on.
3.- Configuration and connection of the relay radiant heat control module
If you have a relay radiant heat control module, configure the SW2 microswitch
depending on the zones to control.
For example: The relay to control the radiant element of a zone module with address 6 is the
R1 of the radiant heat control module with address configured for zones 6-10.
Once configured, perform the connection with the radiant elements to control per each relay output of the module.
Control relay specs: Imax = 1 A at 24/48 V, voltage-free.
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.
4.- Connection to the ducted unit
In order to connect it to ducted unit, follow the instructions of the communication gateway sheet. It is recommended to
install the thermostat of the unit.
5.- Connection of the zone modules with the elements/systems to control (Cassette, Split, etc.)
You can find the instructions on how to connect these elements to the zone modules on their data sheets.

6.- Webserver Cloud connection or BACnet integration gateway
Connect your Webserver Cloud or BACnet Gateway to the automation bus of the Control Board (follow the steps shown on the
technical data sheets).
All Airzone systems must be connected to internet to offer technical support.
It is only necessary to connect one Webserver Cloud per installation (control of up to 32 systems), for
BACnet integration gateway, one per system.
7.- Auxiliary Heat and other peripherals
If your system includes auxiliary heat, connect the auxiliary heat relays of the ZBS Control board to the elements to control.
Control relay specs: Imax = 1 A at 24 V, voltage-free.
Note that to control elements with a greater power, it is recommended to use
contactors in accordance with the power required.
You can find the instructions on how to connect and configure other peripherals on their data sheets.
8.- Powering the system
Use the power input to power at 110 / 230 Vac the main control board and any others
control elements that require it. Use the appropriate cable: 3x1.5mm2(AWG 15 - 3 wired).
For added security, secure the wires using the turret.
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. Use an
independent circuit from the controlled system for the power supply.
Remember: Once all the connections are made, make sure you replace the cover properly.
