Introduction
This fan-coil thermostat control kit CH130RFR
is made up of a CH130RF thermostat and a
DIN bar CH172DRF actuator.
The CH130RF model is a fan-coil 4- or 2-pipe
thermostat that allows you to control the ambi-
ent temperature both in the heating and cooling
mode. These controls are sent to a CH172DRF
actuator that communicates with the CH130RF
through radio frequencies.
The CH130RF is powered by two AA-size bat-
teries (1.5 V). It is able to drive two valves and
control a 3-speed fan-coil motor, in manual
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 stored in a perma-
nent memory capable of keeping the same
even when the batteries are not inserted.

User’s manual
First of all, make sure that the self-learning
procedure has already been performed (page
8); moreover, verify that both the CH130 and
the CH172D are 30 metres far from each other
at the most. In fact, this distance represents
the free air maximum range for the radio fre-
quency modules used by the thermostat and
the actuator. Please note that the range will
decrease if obstacles are found between the
CH130RF and the CH172DRF.
To start the thermostat after the same has
been installed, proceed as follows:
1. Select the Summer / Winter operation;
2. Select the operating mode;
3. Select the fan speed.
“Summer / Winter” selection
To switch from the “Winter” operation (i.e. heat-
ing system) to the “Summer” operation (i.e.
cooling system), and vice versa, press the 1+2
button combination. The selected operation
will be indicated on the display by the “Winter”
or “Summer” icons.

“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 CH130RF 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.

“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 either to three fixed
levels (minimum, medium, maximum) by
pressing buttons “1” and “2”.
Maintenance
The thermostat should be cleaned by using
a soft cotton cloth. No detergent should be
used.
Installation
The thermostat installation involves carrying
out the following operations:
• Fastening the socket;
• Making the electric connections;
• Fastening the thermostat onto the socket;
• Inserting and replacing the batteries;
• Configuring the thermostat parameters.
Warning! The thermostat shall be installed only
by qualified personnel, in strict compliance with
the law regulations in force.

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.
To ensure correct operation, the socket shall
be placed at a height of approximately 1.5 me-
tres from the floor, far from heat sources (direct
sunlight, etc.) and doors/windows.
Electric connections
External probe connection
Connect the two external probe wires with
screwed terminals “1” and “2”, as illustrated in
the figure. Such probe can be configured as
external probe or minimum temperature con-
tact. See the “thermostat configuration” para-
graph, P02 parameter.

range is approximately 30 metres in the free
air).
To perform self-learning, proceed as follows:
keep the CH172DRF button depressed for
at least 5 seconds, until the multicolour LED
comes on by switching among green, yellow,
red and OFF. Then press the CH130RF reset
button: after a few instants, the LED will be
blinking fast and then illuminate green steadily,
to indicate that the self-learning has occurred
(this procedure is also described in the CH172-
DRF instruction sheet).
N.B. You can also control two or several
CH172DRF actuators by means of one single
CH130RF: of course, the self-learning proce-
dure shall be performed on all the CH172DRFs
(it shall not necessarily be performed at the
same time).
Fastening the thermostat onto the socket
Insert and screw the thermostat down to the
socket (make sure that the multi-pole connec-
tor is engaged correctly).
Inserting and replacing the batteries
Insert two “AA” batteries (1.5 V) into the battery
compartment, according to the correct polarity:
the negative pole shall press the metal spring
(located on the right, when viewing the ther-
mostat from the front). Fit the battery top cover
back into place.
A pair of new batteries will normally last one
year at least. WHEN THE “low battery charge”
SYMBOL APPEARS ON THE DISPLAY, BOTH
BATTERIES SHALL BE REPLACED.
CH172DRF self-learning procedure
In order for the CH130RF and the CH172DRF
to be able to communicate correctly, a “self-
learning” procedure shall be performed. During
this procedure, the remote actuator will recog-
nize and store the CH130RF identity: from now
on, it will be able to perform all of its controls
while leaving out the controls from other trans-
mitters that might be found in the area (please
note that the CH130RF/CH172DRF system

Thermostat configuration
The thermostat configuration allows you to
customize the device operation parameters.
To access the configuration program, proceed
as follows:
1. Press the “Reset” button and also button “3”
(with the thermostat ON);
2. Release the “Reset” button, then keep but-
ton “3” depressed for at least 3 seconds.
3. Release button “3”.
The configuration parameters are represented
by an index (P01, P02…) on the display; by
pressing buttons “1” and “2”, the parameter in-
dexes will be scrolled through. Press button “3”
to enter the displayed parameter.
To modify the current parameter, press buttons
“1” and “2”. To exit the parameter, press but-
ton “3”.
Once all parameters have been set, press
button “1” until the “END” message appears,
then press button “3”. Now the thermostat will
save the modified parameters into the internal
memory and will automatically exit the param-
eter menu.
On the contrary, if buttons “1” and “4” are
pressed simultaneously when the “END” mes-
sage is displayed, the CH130RF’s RF address
will be reset and the self-learning procedure
shall be performed again.
N.B. The thermostat will send the switch-on/-off
controls for the three fans and the two valves
to the actuator to a fixed rate of 1 minute.
Warning! The configuration shall be performed
only by qualified personnel.
