In this video we show you how to connect and configure the Airzone-Fujitsu communication gateway.


The gateway is made up of 3 elements:
- A connector for the Airzone system's main control board and a fixing post.
- A configuration microswitch.
- A connector for the Fujitsu AC unit.

1. Turn off the power to both your Airzone system and your Fujitsu AC unit before making the connections.

2. Connect the gateway to the AC unit port on the Airzone main control board and secure it using the fixing post supplied.

3. If the installation has a controller with a two-wire cable, this should be replaced with a three-wire cable. You will also need to configure the indoor unit's microswitch for a three-wire connection.

4. Connect the cable labeled 1, supplied by Airzone, to the TERMOS terminal on the Airzone gateway.

5. Disconnect the Fujitsu controller from the indoor unit’s terminal and connect it to the cable 1 terminal. Make sure you respect the polarity of the wires.

6. Connect the cable labeled 2, from the MAQUINA terminal on the Airzone gateway to the Fujitsu indoor unit's terminal. Make sure you respect the polarity of the wires.

7. Once all the connections are successfully made, configure the microswitch if necessary.
To use the Airzone algorithm, the sensor reading must be configured from the thermostat. See the Fujitsu installation manual.

8. Finally, it’s time to power up the Airzone system and the Fujitsu AC unit.
a. Check all the status LEDs on the gateway to verify correct operation:
 Power supply LED.
 Microprocessor activity LED.
 Communication LEDs (gateway-system).
 Communication LEDs (gateway-AC unit).


b. Once the Airzone system is configured, select any operating mode other than Stop to generate demand in a zone and check that the Fujitsu controller receives the commands from the Airzone system.

c. Finally, check that the static pressure in the ducted AC unit is in accordance with the conditions of the airflow distribution network in which it is installed (see the manufacturer's manual for the AC unit if you need to modify this parameter).
