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.

User’s manual
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 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.

“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.

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.

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;
• Configuring the thermostat parameters.
Warning! The thermostat shall be installed only
by qualified personnel, in strict compliance with
the law regulations in force.

Actuator connection
Connect the power supply wires running from
the CH172D actuator with terminals A and B,
as illustrated in the figure.
The terminals take flexible conductors having
a maximum section of 2.5 mm2.
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
Lower the terminal protection door prior to
making the connections.

10
Auxiliary input connection
Connect the two auxiliary input wires with
screwed terminals “1” and “2”, as illustrated in
the figure.
External probe connection
Connect the two external probe wires with
screwed terminals “3” and “4”, as illustrated in
the figure.
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). Fit the battery top
cover back into place.
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”.
Warning! The configuration shall be performed
only by qualified personnel.
