- Connect the thermostat base to the wall plate (pass the wires
through the rectangular openings). Align the base holes with the
special wall plate teeth, then press the base to the left until the
plate’s plastic teeth click (Fig. 5).
- Fix the thermostat base to the wall with the supplied screw.
If required, correctly set jumpers
JP1
,
JP2
,
JP3
,
JP4
and
JP5
.
Carefully read the “JUMPER SELECTION“ (page 5) and “ELECTRICAL
CONNECTIONS“ paragraphs.
Perform the electrical connections following the connection diagram
(in Fig. 8, 9, 10, 11) and the possible variants (in Fig. 12, 13). Carefully
read the “ELECTRICAL CONNECTIONS“ paragraph.
Perform the following operations to close back the thermostat:
- Position the two teeth on the upper part of the cover in the special
notches.
- Turn the cover and push the plastic tab inwardly on the lower part of
the base (see the arrow in Fig. 9). Press it so that the plastic fixing
tab inside the special hole clicks.

WARNING
- The delivery water sensor must be installed in a way that it can
acquire the correct water temperature even in case the flow is
stopped by the valve itself.
- Wiring the same remote temperature sensor to more than one
controller is not allowed.
- All remote sensors, bimetallic contact and window contact must
have a galvanic insulation against earth as well as against the
mains power.
- In case precending two directions are not respected an irreversible
product damage can follow.
- All remote sensors, bimetallic contact and window
contact must be double insulation (or reinforced insulation) rated
in case they are accessible to people.
- In case the reinforced insulation of the preceding point cannot be
obtained, power the regulator with a 24V~ low voltage (yet in
full compliance with the safety standards).
- The appliance must be wired to the electric mains through a
switch capable of disconnecting all poles in compliance with the
current safety standards and with a contact separation of at least
3 mm in all poles.
- Installation and electrical wirings of this appliance must be made by
qualified technicians and in compliance with the current standards.
- Before wiring the appliance be sure to turn the mains power off.
WIRINGS
This controller can be powered either with 230V~ or with 24V~.
The thermostat is factory set at 230V~, with jumper in position
JP1
,
with frequency at 50Hz, with jumper in position
JP4
. To select 24V~
supply, move jumper
JP1
(Fig. 6) to position
JP2
(Fig. 6). To select 60Hz
frequency move jumper to
JP4
(Fig. 6) to position
JP3
(Fig. 6).
As shown in the wiring diagrams, supply terminals are L and N.
If you have a 230V power supply, the live and neutral must be respected
An input is available on terminal 3 for centralised heating/cooling selection.
An input is available on terminal 4 to activate “Economy” mode.
A window contact can be connected to terminals 14 and 16.
Note
: there are limitations for window contact use. Carefully read the
paragraph “ATTENTION”.
The function of the input terminals 3, 4 and 16 can be changed through
parameters
C17
,
C18
and
C19
.
Signals to terminals 3 and 4 can be connected terminals 3 and 4 of other
