disconnected from the 230V~ mains power supply and
take care not to damage circuits or components.
- Make the electrical connections as explained in the
paragraph on "Electrical connections".
- Configure the device as directed in "Configuring the system".
- Close the device. The cables should be "bent" as shown in
Fig. 3 and made to pass through the cable glands
If you use a cable entry and its respective cable gland,
you will have to remove the plastic tab
suitable pliers to open the passage for the cable. Then
reposition the front panel on the enclosure and fasten in
place with the four screws

ELECTRICAL CONNECTIONS

This sections illustrates how to connect the relay module
correctly: carefully read the directions below and refer to
Fig. 4, which shows the arrangement of the terminals and
how they are connected internally.
Terminals 1 and 2 are power inputs: connect them to the
230V~ mains supply, making sure that terminal 1 is
connected to Neutral. The electronic circuit is internally
protected by means of an auto-reset thermal fuse, while the
loads are protected by the 2A slow-blow fuse, F1 indicated
H
by in Fig. 2. Terminals 13 and 14 are inputs for the
auxiliary power supply of the actuators and terminals from
3 to 6 are the 2 actuator outputs. The module leaves the
factory with jumpers in place to connect terminals 13 and 14
to the power supply line (230V~) and can therefore directly
power the loads connected to its terminals 3 to 6, as shown
in Fig. 4. In this case the auxiliary power supply must not
be connected to terminals 13 and 14 and the loads will be
powered by the 230V~ mains supply.
If the actuators need to be powered at a different voltage
(for example if a load operates at 24V~) the receiver must
be slightly modified as follows:
- Cut jumper wires JP1 and JP2,

in Fig. 3 with

1 in Fig. 1.
I and L in Figure 2,
and remove them completely.
- This operation serves to disconnect the 230V~ power
supply from the internal line for powering the loads.
- Connect an external power source (e.g. a transformer with
a 24V~ output) to terminals 13 and 14 (Fig. 4).
- Connect the actuators to be controlled to terminals from 3
to 6. These loads must be suitable for the voltage supplied
to terminals 13 and 14.
- Check the rating of the protection fuse F1: it must be sized
according to the maximum total current of the loads (see
below).
The user must take account of the energy consumption of
the loads and make sure that the external power source is
capable of supplying the total power necessary in the worst
possible situation (i.e. when all loads are switched on). For
example, if you use 2 actuators each requiring 3W at 24V~,
it will be necessary to provide an external transformer with
a 24V~/6W output (3W x 2 actuators). A safety margin of
at least +10% is strongly recommended: in the preceding
example, this would mean using at least a 8W transformer.
The slow-blow protection fuse supplied, F1, has a trip value
of 2A, which is suitable for 4 standard 230V~ actuators.
If you need to connect a larger number of actuators
or 24 V~ actuators, you should replace fuse F1 with one
having a higher rated trip current. The fuse should be sized
so as to withstand the inrush current of the actuator; in
case of need, ask your local retailer for further information.
Terminals 7 and 8 are the auxiliary output terminals for
connecting a circulating pump or boiler.
These are voltage-free contacts (not powered) so that you
can use a pump or boiler that works at various voltages. The
diagram in Fig. 4 illustrates the connection of a circulation
pump. Terminals 9, 10 and 11 (Fig. 4) are respectively the
external "Global standby", "Heating/Cooling" and "Economy"
inputs that can be closed at terminal 12 to activate the
associated function. The status of the external inputs are
