OVERVIEW
This device is a thermostat intended for temperature regulation in
environments heated or cooled with fan-coil units.
Power supply is 230V~. The device features an outlet to connect
an external temperature probe and another to connect a bimetal
thermostat for the "cutoff thermostat" function.
INSTALLATION
Carry out the operations below to install the device, while following
the images on page 2:
Release the plate attached to the thermostat base by pushing it
1
to the left. This releases the teeth shown in Fig. 2.
Move both sliders all the way down and position the knob at
2
20°C; lift the knob using a screwdriver as shown by the arrow in
Fig. 3, being careful not to scratch the cover.
Push the plastic tab in the lower slot using a screwdriver,
3
slightly lifting the cover (Fig. 4).
Turn the cover, while pressing it slightly, until it is fully extracted
4
(Fig. 5).
Remove the mechanical pins from the thermostat base and
5
insert them in the cover to reduce the knob's field of rotation
(see example in Fig. 6 and read the "knob lock" paragraph).
The third pin at the top is a spare.
Fix the plate to the wall, using the two screw seats with centre
6
distances of 60 mm or 85 mm (use the supplied wall plugs and/or
screws). Pass the wires through the rectangular openings.
- Connect the thermostat base to the wall plate (pass the wires
7
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. 8).
- Fix the thermostat base to the wall with the supplied screws.
- Make
the
electrical
8
appropriate connection diagram (Pages 4, 5, 6 and 7).
- Correctly set the connector JP1 if using a remote sensor.
See the "INTERNAL/EXTERNAL SENSOR SELECTION"
paragraph.
Perform the following operations to reclose the thermostat:
9
- Position the two teeth from the top of the cover into the specific
slots and leave both sliders at the bottom.
- Turn the cover making sure the sliders coincide with the
relative switches, push the plastic tab on the lower part of the
base inwardly (see the arrow in Fig. 7) and press it so that
the plastic fixing tab inside the special hole, at the bottom of
the cover, clicks. Check the sliders' correct stroke.
Position the knob at 20°C and insert it on the cover.

OPERATION
The controls available on the front cover of the thermostat for the
user are two sliders and one knob.
3-SPEEDS SELECTOR
Through this three-position slide selector
the (fixed) speed of the fan-coil motor.
COOL / OFF / HEAT SELECTOR
Through this three-position slide selector
the operating mode of the thermostat as in the following explained:
- Cooling Mode:
Set the slider to the position with the symbol : cooling mode is
then selected.
- Heating Mode:
Set the slider to the position with the symbol : heating mode is
then selected.
- Off Mode:
Set the slider to the position with the symbol 0: the thermostat is
turned off.
KNOB
Through the temperature set-point knob
temperature desired in the room, according to which the regulation
will be performed, in the range +5°C .. +35°C.
KNOB ROTATION LIMITATION
It is possible to limit the rotation range for the set-poin knob by
following these steps:
1. Extract the knob as indicated in "
paragraph.
2. Position the mechanical pins as shown in the example in Fig. 6 (
The field of rotation is, in this way, reduced as in the arc shown
in
F
in Fig. 5.

operation whenever the supply water is not hot enough (heating
mode only).
In order to activate this function it is mandatory to wire a bimetallic
thermostat between terminals 6 and 7.
In case the Supply Water Thermostat is not used, a wire jumper
must be applied between terminals 6 and 7.
INTERNAL / EXTERNAL SENSOR SELECTION
The thermostat leaves the factory already set for an internal sensor
work.
In those installations where a remote sensor is required, please
move jumper JP1 (located on the electronic board on the right side
of the selctors) into position A, as shown in Fig. 6, then wire a
10KΩ @ 25°C NTC sensor with a proper 'Beta' value at connector
SA or, as an alternative, at terminals 12 and 13.
In case of doubts about the sensor to be connected, please ask the
producer.

WARNING
- To adjust properly room temperature, install the thermostat
far from heat sources, airstreams or particularly cold walls
(thermal bridges). When the remote sensor is used in
conjunction with the thermostat, then this note must be
applied to the remote sensor itself.
- For remote versions all wirings must be made using wires
with 1,5 mm² minimum cross section and not longer than
25 m.
Do not use same duct for signal wires and mains.
- 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.
