Applications

Automatic Coffee Makers, Water Heaters, Sandwich Toasters, Dish Washers, Boilers, Dryers, Electric Heaters, Washing Machines, Refrigerators, Microwave Ovens, Water Purifiers, Bidet, etc.

Installations:

Method of earth: By means of the metal cup of thermostat connected in the earthing metal part.

The thermostat should work in environment with humidity not higher than 90%, free of caustic, flammable gas and conducting dust.

When the thermostat is used to sense the temperature of solid items, its cover should be clung to the heating part of such items. Meanwhile, heat-conducting silicon grease, or other heat media of similar nature, should be applied to the cover's surface.

If the thermostat is used to sense the temperature of liquids or steam, it is strongly recommended to adopt a version with stain less-steeled cup. Moreover, cautious measures should be taken to prevent liquids getting into/onto the thermostat's insulation parts.

The top of the cup must not be pressed to sink, so as to avoid adverse effect on the thermostat's temperature sensitivity or its other functions.

Liquids must be kept out of the thermostat's inner part! The base must avid any force that could lead to crack; it should be kept clear and away from the pollution of electric substance to prevent insulation weakening that leads to short-circuited damages.

The terminals should be bent, or else, the reliability of electric connection will be influenced.

Features

• Snap Action

• Manual and Automatic Resettable

• Safety Design according to IEC Standard

• Horizontal and Vertical Terminals Available

• Customized Wire Connection and Bracket Type Available

• Available with Both Normally Closed and Open Type Contacts

Product Advantage

Long life, high precision, EMC test resistance, no arcing, small size and stable performance.

Feature Advantage

Automatic reset temperature control switch: as the temperature increases or decreases, the internal contacts are automatically opened and closed.

Manual reset temperature control switch: When the temperature rises, the contact will automatically open; when the temperature of the controller cools down, the contact must be reset and closed again by manually pressing the button.

How does a Manual Thermostat Work?

A mercury-based manual thermostat contains a sealed tube filled with mercury gas. As the temperature in the home changes, the mercury heats up or cools down. After the mercury reaches a specific temperature, the thermostat sends a signal to the heating or cooling unit to switch on or off.

One of the most operating systems used in the manual thermostat is the bi-metal conductor. These units contain a strip or metal, which can be made from aluminum, tin, steel or some other material depending on the unit. As the room heats up or cools down, the metal reacts to the change in temperature. Once it reaches a specific set point, it sends an electric signal to the furnace or air conditioner to switch on or off.

A manual thermostat may also contain a digital control system, which tends to be the most accurate and reliable of the three systems. With a digital thermostat, an electric temperature gauge senses temperature changes in the room. When the temperature in the room falls above or below the set temperature, the thermostat sends an electric signal to the heating or cooling unit to bring the room's temperature to the desired range.
