Digital inputs
The production control board you have 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 Acuazone/Innobus Pro32 systems working on Air heat will stop and
the message ACS will be displayed by the zone thermostats. This feature is recommended for Aerothermal installations
when the 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: Stop, Heating and Ventilation.
- FRIO: This input activates the semi-forced cooling mode in all the systems of the installation. These are the modes
available: Stop, Dry, Cooling and Ventilation.
- STOP: This input activates the semi-forced cooling mode in all the systems of the installation.
The main control board has an analogical input for connecting a temperature probe to protect the boiler.
External domotic bus connector
The external domotic bus allows the connection of control peripherals in order to manage all the systems connected to the
production control board. These are the elements that can be connected:
- Webserver Airzone Cloud Ethernet/Wifi (AZX6WEBSCLOUD [C/R]). (External Domotic bus 1)
- KNX Integration gateway (AZX6KNXGTWAY).
- Webserver Airzone Cloud DIN Ethernet/Wifi (AZX6WSCLOUDDIN [C/R]).
It has two 5-pin terminals for connection of the domotic bus. This system can only be
connected by bus. Attach the wires with the terminal screws following the color code
(Fig. 69).
Note: For elements externally powered at 110/230 Vac, for the communications, it is only
necessary to connect the poles "A" and "B" of the domotic bus.
When connecting the webserver Cloud (AZX6WEBSCLOUD [C/R]), remove the fixing port
from the Webserver and fit the connector into the external domotic bus 1(Fig. 70).
