Predisposition input for disabling Hydro.
The Hydro board provides for the possibility of a remote
disabling command; to use this function it is necessary to
connect the cable supplied with the unit to the CN3 connec-
tor as shown in the wiring diagram in Fig. 3 (the command
must be equipped with a potential free contact. If the contact
is open the system is controlled by the remote control; if the
contact is closed the unit is forced off).
To connect the wiring, make sure that the power supply is
disconnected. Then access the electronic card that is below
the area of the terminal board; to access it, remove the front
panel and remove the screws of the box cover containing
the electronic card.
Once the supplied wiring is connected, it will be possible to
close the card compartment and then connect the cable to
the device disabling command via terminals not supplied.
On/off control by Hydro.
Clean contact, provided by Hydro, with loads up to 700 mA.
The contact is closed if there is a demand for heat/cool/dry
mode on Hydro.
In the absence of requests the contact remains open.
