Remember:
Once all the connections are made, make sure you replace the cover properly.
Digital inputs
The production control board has 4 digital inputs to externally control the Airzone systems. These inputs are configured as
normally open. It is recommended to use a shielded cable to connect it.
ACS: This input activates the DHW mode: all the systems working on Air heat will stop and the message DHW will be displayed
by the zone thermostats. This feature is recommended for Aerothermal installations when the Aerothermal unit starts
producing DHW.
CALOR: This input activates the semi-forced heating mode in all the system of the installation. These are the modes available
to select: Stop, Heating and Ventilation.
FRIO: This input activates the semi-forced cooling mode in all the system of the installation. These are the modes available to
select: Stop, Cooling, Dry and Ventilation.
STOP: This input activates the Stop mode in all the system of the installation.
The main control board has an analogical input to connect a temperature probe for boiler protection.
Domotic bus connectors
The indoor domotic bus allows you to connect the production control board with the main control
board and aerothermal gateways (AZX6GAWxxx). The domotic bus has two terminals which are
interconnected so that can be used interchangeably. This system can only be connected by bus. Attach
the wires with the terminal screws following the color code. Use the shield only on the connector of the
main control board, not required in RadianT system.
Note:
For a proper operation of this main control board, all main control boards must be addressed (up to
32 zones) (see section Advanced settings).
Control relays
This device has 7 relays for controlling the installation. The characteristics of the control relays are I
max
: 10 A at 110/230 Vac
(tension-free). Note that to control elements with a greater power, it is recommended to use contactors in accordance with the
power required.
Important
: Remember to connect the neutral connector directly from the circuit to the element to be controlled.
Depending on the type of installation, the control relays will follow a different logic:
