SYSTEM INSTALLATION
Before performing the Airzone system installation, check:
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:
Locate all the elements and perform the connection (See section
-
Zone and Control Modules connection with the Airzone ZBS Control board. Connect the zone modules of the
system to any of the 3 Airzone connection bus terminals. Use the proper cable: shielded twisted pair 4 wired:

the turrets.
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.
-
Connecting the thermostats. Connect each thermostat to the terminal corresponding to its zone module. Use the
proper cable: shielded twisted pair 4 wired: 2x0.22 mm
check it has the battery on.
-
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. Once configured, perform the connection
with the radiant elements to control per each relay output of the module.
-
Connection to the ducted unit (see section Gateway Connection). It is recommended to install the thermostat of the
unit. For the connection of DIN rail gateways to the control board, use the proper cable: shielded twisted pair 2 wired:

Connection of the zone modules with the elements/systems to control (Split, etc.). (See section zone module
connection).
