5. Setup and Installation

Proper installation is crucial for the accurate and safe operation of the thermostat. Follow these steps carefully:

1. Disconnect Power: Before beginning any installation, ensure that the power supply to the appliance or system where the thermostat will be installed is completely disconnected.
2. Mounting the Thermostat: Securely mount the main body of the thermostat in a suitable location, away from direct heat sources or excessive vibrations.
3. Probe Installation:
   • For applications like a radiator or cooler, remove the upper cooler component.
   • Fully insert the capillary probe into the radiator inlet tube. Ensure the probe is positioned correctly and will remain stable within the hose.
   • Reattach the cooler component and tighten it onto the capillary wire. Exercise caution to avoid damaging the probe inside during this process.
   • If necessary, a silicone sealant can be applied to ensure a proper seal and prevent leaks.
4. Wiring Connections: Connect the thermostat according to the specific wiring diagram for your application. The thermostat has terminals for electrical connections. Refer to the diagram below for a typical automotive fan setup example.

6. Operating Instructions

Once installed and wired correctly, operating the RANRAO Capillary Thermostat is straightforward:

1. Power On: Restore power to the system or appliance.
2. Set Temperature: Rotate the temperature adjustment dial on the front of the thermostat to your desired temperature setting within the 0℃ to 120℃ range. The markings on the dial indicate the temperature in degrees Celsius.
3. Automatic Operation: The thermostat will monitor the temperature via its capillary probe. When the sensed temperature reaches or exceeds the set point, the connected device (e.g., heating element, fan) will activate.
4. Deactivation: The connected device will automatically deactivate when the temperature drops below the set point, maintaining the desired temperature range.
