Power supply connector
This connector powers the main control board and all the elements connected to it. Externally
powered at 110/110/230 Vac. It is connected through a 3-pin terminal. Attach the wires with the
terminal screws following the color code. For added security, secure the wires using the turret.
Important: 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.
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.
