The documentation reflects the characteristics of the product. However, for regulatory or commercial developments, customers should verify the availability of updates relating to this documentation on the FANTINI COSMI S.p.A. website: pdf.fantinicosmi.it

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

DIN RAIL CH176D ACTUATOR

OPERATION

The CH130AR2 unit is an actuation model which, connected to a thermostat for fan coil CH133AR2 – CH133RR – CH130AR2 – CH130ARR – CH130RR via a bipolar cable, allows to remotely control the two valves, the three-speed motor or a 0 .. 10V, motor, and accept a temperature sensor connected to the appropriate input.

The bipolar cable connecting the module to the thermostat, has a dual function:

• powering the fan coil thermostat,
• communication bus between thermostat and actuation module.

The CH130AR2C unit is compatible with the CH172D actuator via external set-up. It is possible to connect a single thermostat to several actuators, so as to control more than one fan coil simultaneously with only two cables; for this application, carefully follow the detailed instructions in the document.

TECHNICAL FEATURES

• Power supply and absorbed power 230Vac 50Hz – 2VA
• BUS A/B input Power supply + thermostat data (default setting: SLAVE)
• Relay output features 5(3)A 250V~
• Voltage-free switching contacts with mains voltage 2 valve outputs (N-V1 and N-V2)
• Mains voltage switching contacts 3 motor contact outputs (M1, M2 and M3) 0 … 10V output 20 mA – 470Ω
• Probe input NTC 10 KΩ (Fantini EC15-EC18-EC19-EC20)
• Protection rating IP00
• Software class A
• Maximum temperature T45
• Degree of pollution 2
• Complies with Standards EN60730-1 and second parts
• Micro-disconnection 1B
• Impulse voltage 4000V
• Assembly type and dimensions 6-module DIN Rail

The device is designed for installation on DIN rail, but its small size facilitate the installation inside the fan coil also.

ATTENTION!
The end parts (live) of the CH176D must be installed in a container or fan coil inaccessible by the user. Installation must be carried out by qualified personnel, in compliance with the requirements concerning installation of electrical devices. Make sure that the power network is disconnected before making any connections or working on the device.

• The following figure shows the circuit diagram of the connections.
• The distance between the actuator module and thermostat must not exceed 100 metres.
• In air conditioning systems with four pipes, valve 1 (terminals N and V1) controls the heating circuit while valve 2 (terminals N and V2) controls the cooling circuit.
• The temperature sensor (NTC 10KΩ) must be connected to the PROBE input. The 0 … 10V motor must be connected to the specific 0-10V OUT output, respecting its polarities.

CONNECTING SEVERAL MODULES TO ONE THERMOSTAT
A CH133AR2 – CH133RR – CH130AR2 – CH130ARR – CH130RR thermostat can control up to five fan-coils simultaneously, using only two wires to connect to the various actuation modules. In this case, only one of the two CH176D modules must have the “BUS selector” in “MASTER” position, while all others must be left in “SLAVE” mode (default setting). The temperature probe connected to the actuation module set up as “MASTER” is the one read by the thermostat. The connection between the various devices must be made as per the diagram in the following figure

OPERATING MODE SELECTION

If thermostats CH133RR – CH130RR – CH130ARR are connected to the actuation module, it must be configured in CH172D mode. The selection is made by switching on the actuation module by means of the configuration of the probe input according to the following diagram:

• CH176D: probe input free or connected to a temperature probe
• CH172D: temperature probe input permanently short-circuited by means of a conductor cable

LUMINOUS STATUS INDICATOR

• The CH176D unit is equipped with a status indicator made via a two-coloured LED diode.
• Flashing red: the actuation module is configured as Master and is receiving a command from the thermostat.
• Flashing green: the actuation module is configured as Slave and is receiving a command from the thermostat.
• Flashing red and green alternately: protection. After twenty minutes during which the actuation module does not receive commands from the thermostat, the relays are deactivated and the 0 … 10V output is brought to 0V.
• Upon reception of a command, the actuation module resumes normal operation

COMMISSIONING AND OPERATIONAL CHECK

Commissioning and testing procedure:

•  make sure that the actuator is properly connected to the thermostat;
•  set the “BUS selector” to ON (MASTER);
•  set up the actuation module as CH176D or CH172D (according to the thermostat connected to it);
•  supply 230Vac power to the actuator;
•  check that the thermostat is turned on;
•  by consulting the manual of the thermostat, set it in the different operating modes (winter and summer) with consistent set-points and gradually select the various ventilation speeds (1, 2 and 3), check switching of the various relay and the subsequent actuations of the V1/V2 valves and the fan coil motor

A black bar indicates that the product was placed on the market after 13 August 2005. Participating in the separate collection of products and batteries contributes to the correct disposal of these materials and therefore avoids possible negative consequences for the environment and human health. For more detailed information on the collection and recycling programmes available in your country, contact the local authorities or the sales point where you purchased the product.
