1. When the contact temperature sensing installation is adopted, the metal cover should be close to the installation surface of the controlled appliance. In order to ensure the temperature sensing effect, the heat conducting silicone grease or other heat conducting medium with similar performance should be coated on the temperature sensing surface.
2. Do not collapse, loosen or deform the top of the cover during installation, so as not to affect the performance. 3. Do not allow liquid to penetrate into the inside of the temperature controller, crack the shell, and change the shape of the external terminal at will.
4. When the product is used in the circuit with current less than 5a, the copper core section should be 0.5-1mm
2. Wire connection, The copper core with a cross section of 0.75-1.5mm shall be selected for the circuit with current less than 10A
2 wire connection. 5. The products should be stored in the warehouse with relative humidity less than 90% and ambient temperature below 40 ?, which is ventilated, clean, dry and free of corrosive gas.
