Analogue outputs (AOxx)
These terminals send analogue 0-10Vdc regulation signals to modulate the control of outlet units with mixture, aerothermal brine
units with variable speed fan, external auxiliary boilers, etc. On the other hand, these connectors have a 24Vac power supply terminal
to supply the modulating valve motor.

Digital outputs to relay (DOxx)
These terminals provide 230Vac activation signals for various external components, such as outlet units, open / close 3-way valves,
external auxiliary equipment, etc. The connectors used for valve control allow connection of any type of 2 or 3-point control valve,
as long as it has a single-phase 230Vac power supply.
Pay special attention to the maximum consumption allowed by each connector. Use an intermediate
relay for the connection, if necessary.
