Introduction
This fan-coil thermostat control kit CH130ARR
is made up of a CH130AR thermostat and a
DIN bar CH172D actuator.
The CH130AR model is a fan-coil 4- or 2-pipe
thermostat that allows you to control the ambi-
ent temperature both in the heating and cool-
ing mode. These commands are sent to a
CH172D actuator connected to the CH130AR
by means of a two-pole cable.
The CH130AR is powered directly by the ac-
tuator and is able to drive two valves and also
control a 3-speed fan-coil motor, either in man-
ual or automatic mode.
The thermostat measures the ambient tem-
perature either through an internal probe or an
external sensor. It keeps the set-point by act-
ing on the ventilation speed.
The wide display shows the measured tem-
perature, the fan speed, the program being run
and the selected season.
The settings and data are store in a permanent
memory that will retain them even when the
thermostat is not connected to the CH172D.

“Economy” operating mode
With the “Economy” operating mode, the ther-
mostat regulates the heating or cooling system
operation in order to always keep the same
economy temperature set. To switch from
“Comfort” to “Economy”, press buttons “3” and
“4” simultaneously.
The temperature level can be modified during
operation by means of buttons “3” and “4”. The
temperature can be changed from 2°C to 40°C
by 0.1°C steps.
Operating modes
The CH130AR thermostat features three dif-
ferent manual operating modes: “Comfort”,
“Economy”, and the “OFF” function (OFF).
“Comfort” operating mode
With the “Comfort” operating mode, the ther-
mostat regulates the heating or cooling sys-
tem operation in order to always keep the
same comfort temperature set. To switch from
“Economy” to “Comfort”, press buttons “3” and
“4” simultaneously.
The temperature level can be modified during
operation by means of buttons “3” and “4”. The
temperature can be changed from 2°C to 40°C
by 0.1°C steps.

7
“OFF” function (OFF)
The “OFF” function can be achieved by setting
the fan speed to zero: in this case, the thermo-
stat will carry out no heat regulation, not even
the antifreeze one.
The system will switch off automatically, and
the “OFF” message will appear on the display.
Fan speed selection
The fan speed can be set to three fixed levels
(minimum, medium, maximum) or automati-
cally, by pressing buttons “1” and “2”.
The “Auto” mode allows you to automatically
change the fan speed depending on the ambi-
ent temperature.

8
Fastening the socket
The thermostat is supplied complete with a
socket suitable for mounting both on the wall
and to rectangular or round built-in 3-seat
boxes (503).
Remove the thermostat top cover.
Separate the thermostat socket and front by
removing the screw by means of a suitable tool
and taking the front part off.
Fasten the socket to the desired surface by
means of the special fastening holes; make
sure that the socket is properly engaged, with
no deformation, and that the connecting multi-
pole connector is located in the right bottom
corner.

P01: Type of system
1two-tube system: the thermostat will drive
only the valve (ON/OFF type) used for heat-
ing both during the heating and the cooling: in
fact, the valve will control both hot water and
cold water.
2four-tube system: the thermostat will drive
one valve (ON/OFF type) used for heating,
plus one additional valve (ON/OFF type) used
for cooling, depending on the needs of the en-
vironment.
P02: External probe
1 resumption: instead of the probe incorporat-
ed into the thermostat, an external probe can
be used to read the ambient temperature and
carry out heat regulation. Typically, this probe
will be positioned under the fan-coil where air
is sucked.
2 changeover: the external temperature probe
can be placed on the fan-coil delivery tube of a
2-tube system to perform automatic changeo-
ver between the “Summer” operation and the
“Winter” operation. To achieve this, you will
have to set the two actuation thresholds P12
and P13. Please note that either the ambient
temperature (P03 set to 1) or the set-point (P03

13
set to 2) will be shown on the display, yet the
changeover temperature will not be shown.
3minimum window/thermostat contact: when
the contact is open, the thermostat will carry
out heat regulation; when it is closed, the heat
regulation will not be carried out.
4inverted minimum window/thermostat con-
tact: the window contact will operate with an
inverted logic with respect to the statements
made in previous step 3.
5none: the external probe input will not be
controlled by the thermostat.
P03: display visualization
1ambient temperature: the ambient tempera-
ture will be shown on the display.
2set-point: the current set point will be shown
on the display.
P04: “Summer” valve type
1 normally open: in this case, the water flow
is normally open and will be closed when the
valve is fed.
2normally closed: when the valve is energized,
it will open the water flow.
P05: “Winter” valve type
1normally open: in this case, the water flow
is normally open and will be closed when the
valve is fed.
2normally closed: when the valve is energized,
it will open the water flow.
P06: auxiliary input configuration
1ON/OFF: in the event that several thermo-
stats have been installed, you may decide
either to drive all of them in the normal opera-
tion condition (ON) or take advantage of the
OFF function (see page 5) by making use of
one single control through a central point. The
thermostat will be configured to OFF (OFF
function) when the input is powered with 24 V
(d.c. with no polarity obligation or a.c.); on the
contrary, it will remain active when the input is
free from voltage.
2 Summer/Winter: as with the previous case,
the thermostat will be configured to “Summer”
when the input is powered with 24 V (d.c. with
no polarity obligation or a.c.); on the contrary,
it will remain in the “Winter” mode active when
the input is free from voltage.
3none: the thermostat will carry out no opera-
tion, whatever the input status.

14
P07: ambient temperature correction
It can be adjusted from –4.0 to 4.0°C. This pa-
rameter is used to correct the acquired ambient
temperature. As a matter of fact, the ambient
temperature reading may, on some instal-
lations, not be satisfying, owing to the probe
location (i.e. internal or resumption). With this
parameter, a constant value upon reading can
be added to or subtracted from.
P08: “Winter” lower limit set-point tempera-
ture
It can be adjusted from 2.0 to 40.0°C. It rep-
resents the lower limit for all the set-points
(“Comfort” and “Economy”) in the heating
mode.
P09: “Winter” upper limit set-point tem-
perature
It can be adjusted from 2.0 to 40.0°C. It rep-
resents the upper limit for all the set-points
(“Comfort” and “Economy”) in the heating
mode.
P10: “Summer” lower limit set-point tem-
perature
It can be adjusted from 2.0 to 40.0°C. It repre-
sents the lower limit for all the set-points (“Com-
fort” and “Economy”) in the cooling mode.
P11: “Summer” upper limit set-point tem-
perature
It can be adjusted from 2.0 to 40.0°C. It rep-
resents the upper limit for all the set-points
(“Comfort” and “Economy”) in the cooling
mode.
P12: changeover lower threshold
It can be adjusted from 0 to 24°C. It defines
the changeover function lower threshold. Be-
low this temperature, the thermostat will be set
to the cooling mode, if P02 is set to configura-
tion 2.
P13: changeover upper threshold
It can be adjusted from 26 to 48°C. It defines
the changeover function upper threshold.
Above this temperature, the thermostat will be
set to the heating mode, if P02 is set to con-
figuration 2.
P14: differential adjustment
It can be set staring from ±0.3°C (value suit-
able for slow-inertia systems) to ±2°C (value
suitable for very reactive systems).

DIN bar CH172D actuator
Application and use
One single CH130AR thermostat can be con-
nected with several actuators, so as to simulta-
neously control several fan-coils by using only
two cables (see below).

16
Fastening and connecting
The unit has been designed to be built in (in-
side fan-coils, special panels or other suitable
housings).
The unit shall be installed by qualified person-
nel in accordance with the EN regulations in
force.
The distance between the actuator and the
transmitter shall not exceed 100 m.
Connect the wires to the socket terminal block
in accordance with the diagrams illustrated be-
low.
If a two-tube system is available, connect only
valve “1” (contact between terminals “C” and
“V1”). In case of a four-tube system, valve “1”
is dedicated to heating, whereas valve “2” (be-
tween “C” and “V2”) is dedicated to cooling.
WARNING! Prior to carrying out any operation
on the unit, make sure that you have discon-
nected the mains connecting cables.
Operation check
Refer to the specific user manual for the in-
struction on how to use the CH130AR thermo-
stat.
• Make sure that the actuator is correctly con-
nected with the thermostat.
• Power the actuator by connecting the same
with the electric mains.
• Switch over, on the thermostat, the fan mo-
tor speed (3 relays) and the valve control (2
relays), then verify that they have actually
switched over.
