OPERATION
The unit CH130ARR2 is a kit consisting of a thermostat CH130AR2 and an actuator CH176D that connected with a bipolar
cable, allows the remote control of two valves, the three-speed motor, or a 0 ..10V motor, of a fan coil. The thermostat
reads the room temperature and controls it from the fan coil’s motor valves and speed in order to obtain the best climate
comfort. Fan adjustment can be automatic or manual, depending on the settings made by the user from the function
keys, which, together with the LCD screen facilitates daily operation of the system. The non-polarised bipolar cable
connecting the thermostat to the module has dual function:
■thermostat power supply,
■communication bus between thermostat and actuation module.
It is possible to connect a single thermostat to several actuators in order to control more fan coils simultaneously with
only two cables. For this application, follow the detailed instructions in the unit installation manual CH176D.

■Remove the top cover of the thermostat.
■Divide the base and front of the thermostat by removing the screws with a specific tool and extracting the front part.
■Fix the base to the required surface by means of the specific fixing holes; and make sure that the base is well secured,
without deformations and that the multi-polar connector is at the bottom right corner.
■For proper operation, the base must be approximately 1.5 metres above the floor, away from heat sources (direct
sunlight, etc.) and from doors and windows.
■Insert the thermostat on the base and screw it, making sure that the multi-polar connector is inserted properly.
■Refit the top cover.

For further information regarding connection of the thermostat-actuator-fan coil system, refer to the connection diagrams
in the CH176D unit installation manual. Electrical connections must be carried out as shown in the connection diagram.
Please note that connection of the external probe (EXP1) and input for remote control (SEL1), are subject to certain
configuration parameter settings.
Connection of auxiliary input
Connect the two auxiliary input wires to the screw terminals 1 and 2, as shown in the figure.
Connection of the external probe
Connect the two wires of the external probe to the screw terminals 3 and 4, as shown in the figure.
Connection of the actuator
Connect the power wires coming from the actuator CH172D to terminals A and B, as shown in the figure.
Flexible conductors with a max cross-section of 2.5 mm2 can fit in the terminals.
