manually reset thermostat vStructure and application:

The temperature controllers take bimetallic strip as the temperature-sensing unit. In case of normal operation the electrical appliance, the bimetallic strip is in a free state; the contact point is in a state of close/open. When the temperature reaches the action temperature, the bimetallic strip performs quick action, When the electrical appliance is cooled down to the recovery temperature, the contact point can not automatically reset , the people should press down the reset handle with acting force if the contact need to be reset once again, in this way ,the thermostat control the disconnection and connection of circuit.  (Note: 1) It is necessary that you should only press down the reset handle when the temperature drop down by 20°C after the contact action. 2)  In order to make sure the normal operation of thermostat, the vertical space between reset handle and thermostat temperature sensing cover should be more than 20.4mm.)


Stable performance, high accuracy, small size, lightweight, high reliability, long lifespan, less interference to radio Precautions:

1.When adopting contact temperature sensing installation, the surface of the metal cover is required to be securely contacted with the installing surface of the controlled device. For ensuring the temperature sensing effect, it is required to coat thermal conductive grease or other similar thermal conductive medium on the surface of temperature sensor.2.For reliable performance, collapse, loose or distorted top part of the cover is prohibited during installation.3.Liquid inleakage into the controller, crackle in the casing and unauthorized change of external terminal position are prohibited.4.When the product is used in the circuit with maximum current of 5A, the cable with copper core at section 0. 5-1mm2 is required for connection; When the product is used in the circuit with maximum current of 10A, the cable with copper core at section 0.75-1.5 mm2 is required for connection;5.The product should be kept in a clean, dry and corrosive gas-free warehouse with good ventilation and at relative humidity below 90%, environment temperature below 40°C.
