4.- Connection to the ducted unit
In order to connect it to ducted unit,
follow the instructions of the communication gateway
datasheet
. It is recommended to install the controller of the unit.
For the connection of DIN rail gateways to the control board, the appropriate cable: shielded twisted pair
cable formed by 2 wires: 2x0.22 mm
2
(AWG 24 – 2 wired).
5.- Connection of the zone modules with the elements/systems to control (Fancoil, 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 VAF 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.
Important:
The Airzone system is not compatible with electric duct heaters, it may result in system malfunction
and/or fire.
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: 3x1.5mm
2
(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.
