4. Setup and Installation
Follow these steps for proper installation of the C01A thermostat:
- Select Location: Choose a suitable location on the pipe where accurate temperature sensing is required. Ensure the pipe surface is clean and free from insulation at the point of contact.
- Attach Thermostat: Place the thermostat's sensing surface firmly against the pipe. Use the provided elastic metal mesh band to secure the thermostat to the pipe. Ensure the band is tightened sufficiently to maintain good thermal contact between the thermostat and the pipe.
- Electrical Wiring:
- Before wiring, ensure the main power supply to the system is OFF.
- Connect the electrical wiring to the thermostat terminals. Refer to the specific wiring diagram provided with your product packaging or consult a qualified electrician for correct connections. The thermostat is designed for 230 Volts operation.

5. Operating Instructions
The Fantini Cosmi C01A thermostat is simple to operate:
- Temperature Setting: Locate the temperature adjustment dial on the front of the thermostat.
- Adjusting Temperature: Rotate the dial to align the indicator mark with your desired temperature setting. The thermostat will then monitor the pipe temperature and activate or deactivate the connected heating or cooling device (e.g., pump, boiler) to maintain the set temperature.
- The thermostat operates on a liquid expansion principle, providing a reliable and responsive temperature control mechanism.
