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.
