Indoor domotic bus connectors
The internal domotic bus allows you to interconnect the production control board to the main
control board or mains control board. It has a 2-pin terminal for the domotic bus connection.
This system can only be connected by bus. Attach the wires with the terminal screws following
the color code (Fig. 71).
Note: For a proper operation of the main control board, all the main control board must be
addressed (up to 32 systems) (see section Advanced Settings).
Aerothermal gateway bus connector
The AC unit bus allows you to connect multiple gateways of for air-to-water
equipment installed. These are the elements that can be connected:
- Daikin aerothermal gateway (AZX6ACUACP [DAI/DA2]).
In order to connect these gateways, disconnect the terminal of the AC unit bus
and fit in the connector and the fixing post of the gateway (Fig. 72).
Control relays
This device has 6 relays for controlling the installation. The characteristics of the control relays are I
max
of 10 A at 110/230 Vac
(voltage-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:
