1. Grounding method: It is connected to the grounding metal parts of the equipment through the metal cover of the thermostat.
2. The thermostat should work in the general indoor environment where the relative humidity of the air is not more than 90%, and there are no corrosive gases, flammable gases and conductive dust.
3. When the thermostat adopts contact temperature sensing, the cover should be close to the heating part of the controlled device, and the thermal grease or other thermal conductive medium with similar performance should be coated on the temperature sensing surface of the cover.
4. When the thermostat is in contact with liquid or steam, it is recommended to use stainless steel capped products, and there should be reliable leak-proof measures to prevent the liquid from seeping into the insulating parts of the thermostat.
5. Do not collapse or deform the top of the cover, so as not to change the operating temperature or affect other performance.
6. Do not let the liquid penetrate into the inside of the thermostat! The housing must be protected from excessive force to prevent cracks; The housing should be kept clean to prevent contamination by conductive substances to avoid short-circuit breakdown due to reduced insulation properties.
7. The terminal block cannot be bent during use, otherwise the reliability of the electrical connection will be affected.
8. The power supply shall not exceed the declared voltage and current, and the load power and type shall meet the declared requirements, and the ambient temperature shall not exceed the declared maximum allowable temperature.
Precautions (KSD301 manual reset): After the temperature drops by 20 °C, the reset handle can be pressed, and the force is 4-6 Newtons, not too large. In order to ensure that the thermostat can work normally, the vertical distance from the end face of the reset handle to the temperature sensing surface of the cover is not less than 20.4mm.

RKC Thermostat – What are the common faults of thermostats?
1. There is no manifestation when the power is on. For this kind of problem, first confirm whether the power supply is there and whether the power supply matches the power supply required by the thermostat, and then check whether the wiring is strong. The problem is still there, then it is the problem of the thermostat itself.
2. There is a manifestation, and the manipulation makes mistakes. The first thing to look at this kind of problem is to look at the control ...
