GENERAL REQUIREMENTS
Strictly follow the directions outlined in this manual:
•This system must be installed by a qualified technician.
•Verify that the units to be controlled have been installed according to the manufacturer's requirements and operate
correctly before installing the Airzone System.
•Locate and connect all the devices of the installation in accordance with the electronic regulations in force.
•Verify that the air conditioning installation to be controlled is in accordance with the regulations in force.
•To install the flexible duct, follow the local recommendations for its ubication and isolation of the ducts to the damper.
Perform a cut along the isolated area to maintain the actuator of the damper outside it. Once finished, check the
tightness of the joints between the damper and the duct.
•On zones controlled by wireless controllers, place the dampers and zone modules as close as possible to the wireless
controller of the zone.
•Follow these recommendations to locate the controllers:
•Make all the connection with total absence of power supply.
•In order to connect the elements of the system, use only Airzone 4 wires cable: 2x0.22 mm2 shielded twisted wires for
data communication and 2x0.5 mm2 for power supply. The connection between the control modules must be
made in Bus mode.
•Do not place the system bus close to lines of force, fluorescent lights, LED lamps, motors, etc. It might cause
interference on the communications.
•Respect the connection polarity of each device. A wrong connection may seriously damage the product.

13
•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.
•For elements externally powered at 110/230 Vac, respect the connection polarity. A wrong grounding may produce
electric shocks.
•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.
•Once the Airzone system is configured, verify that the static pressure of the duct system complies with the air
distribution network conditions where is installed (check the Manufacturer’s Manual of the equipment if you need to
modify this parameter).

twisted pair 4 wired: 2x0.22 mm2 + 2x0.5mm2(AWG 20 – 4 wired). They must be connected by bus. For added security,
secure the wires using the turrets.

14
IMPORTANT: The maximum number of zone modules connected without their own power supply to the Airzone VAF
control Board is: 6 zone modules connected to Blueface controllers or 10 zone modules connected to Think or Lite
controllers. To add more zone modules, it is necessary to install the supplementary power supply unit (Airzone VAF
additional 12V power supply). Every supplementary power supply unit is enough for 6 or 10 modules as stated before.
-Connecting the controllers. Connect each controller to the terminal corresponding to its zone module. Use a proper
cable: shielded twisted pair 4 wired: 2x0.22 mm2 + 2x0.5mm2(AWG 20 – 4 wired). In case of Wireless controller, 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.
Important: The Airzone system is not compatible with electric duct heaters, it may result in system malfunction and/or fire.
-Connection to the ducted unit (see Gateway datasheet). It is recommended to install the controller of the unit. For
the connection of DIN rail gateways to the control board, use the proper cable: shielded twisted pair 2 wired: 2x0.22

•Remote probe: This function allows you to read the room temperature even if you are not where the controller is
located. Connect the probe and configure the module as main module (connected controller). The state and the set-
point temperature are set via controller while the probe reads the room temperature.
•Distributed probe: This function allows you to control a secondary zone with room temperature reading
independent from the main zone. Connect the probe and configure the module as secondary (disconnected
controller). The state and the set-point temperature are set via controller while the probe reads the room
temperature.
Note: If a temperature probe is installed in one zone, it is not possible to read or control the humidity of that zone.
The module has several inputs to control based on the occupancy or if there are open windows.
•Control by occupancy: When the occupancy sensor connected to the module indicates that the zone is unoccupied,
the system waits for 5 minutes to confirm it is actually empty. After this period of time, the zone is set to Timer Mode
and it turns off after 90 minutes.
•Control by open window: When the open window sensor connected to the module indicates that a window is open
for more than 60 seconds, the control element (actuator/relay) associated with that module closes.
The activation and configuration of these inputs are available in the zone settings menu of the controller (See Advanced
Settings).
Flow regulation
The intelligent motorized dampers include a control system that allows to manually set the maximum and minimum opening
of each damper.
Flow adjustment (REG)
The damper offers a maximum opening adjustment which balances the airflow of each damper based on the real needs of the
installation. By default, the damper is set at the I position. To adjust it, follow the steps:
1. Turn on and generate demand in all zones to open all the dampers.
2. Turn off the zone/damper to be adjusted.
3. Adjust the maximum opening you want with the REG lever (I/II/III/IV).
4. Turn on the zone and check the flow is correct.
Minimum Air Setting (A-M)
The damper enables the adjustment of a minimum opening. By default, the damper is set at the “a” position. To adjust it, follow
the steps:
1. Turn on and generate demand in all zones to open all the dampers.
2. Adjust the minimum opening you want with the M-A lever (a/b/c/d).
3. Turn on the zone and check the minimum air flow is correct.
