7. Install the electrical connections in accordance with the appropriate wiring diagram (page 3) and
the possible variants (page 4). Read the “ELECTRICAL CONNECTIONS” paragraph carefully.
8. To close the controller again, proceed as follows:
-
-
Position the two teeth on the upper part of the cover so they enter the corresponding notches.
Rotate the cover and push the plastic tab inward on the lower part of the base (identified by
the arrow). Press it so that the plastic locking tab clicks into place in the corresponding hole.
WARNING
•
•
•
The supply water sensor must be installed so it can monitor the water
temperature correctly, even if the valve interrupts the flow.
The same remote temperature sensor may not be connected to the
terminals of more than one controller.
The remote sensors, bimetallic contact and window contact connected
to the controller must be isolated from earth and the mains supply
voltage.
Failure to observe the above two conditions may result in irreversible
damage to the product.
The remote sensors, bimetallic contact and window contact must
be double insulation (or fitted with reinforced insulation) if they are
accessible to personnel.
•
•
•
•
If it is not possible to insulate the components as described above,
the controller must be connected to a 24 V~ low voltage power supply
(ensuring it is fully compliant with the safety standards).
The appliance must be connected to the electric mains via a switch
capable of disconnecting all poles in compliance with the current
safety standards and with a contact separation of at least 3 mm on all
poles.
•
•
This appliance must be installed and wired by qualified technicians and
in compliance with the current standards.
Make sure the mains power is off before wiring the appliance.
ELECTRICAL CONNECTIONS
The controller may be connected to either a 230 V~ or a 24 V~ power supply.
The controller is factory set at for a 230 V~ power supply, with the jumper in position JP1, at a fre-
quency of 50Hz, with the jumper in position JP4. To select the 24 V~ supply option, move jumper
JP1 (Fig. 6) to position JP2 (Fig. 6). To select the 60Hz frequency option, move jumper to JP4 (Fig.
6) to position JP3 (Fig. 6).
As shown in the wiring diagrams, the power supply terminals are designated L and N. Ensure the
live and neutral lines are connected to the correct terminals when using a 230 V power supply. An
input used for selecting centralised heating/cooling is available on terminal 3.
An input used for activating “economy” mode is available on terminal 4.
