The 1645613-2 specification has been developed by the International Electrotechnical Commission (IEC) to standardize the “Fields of Application and Working Principles of Non-Programmable Temperature Controllers and Thermostats”. The specification applies to devices that control the temperature of a system, typically by controlling a heater or cooling system that maintains a temperature of a room or product. The specification is the result of considerable effort to address the many safety and performance considerations in using temperature controllers and thermostats.

Temperature controllers and thermostats are used in many applications, including home and commercial HVAC (heating, ventilation, and air-conditioning) systems. In general, temperature controllers are more complex than thermostats and are often used in applications where a greater degree of control over the temperature is needed. For example, a temperature controller might be used in a refrigerator to regulate the cooling of the system while providing a consistent and reliable temperature.

Temperature controllers and thermostats are typically powered by electrical power, although some systems may use natural gas. The power supply may be connected to a standard AC or DC voltage source, or it may connect directly to the system being controlled. The controller is typically an electronic device with a microprocessor, memory, and other components that enable the device to control and monitor the temperature within a given range.

Temperature controllers and thermostats operate by sensing the temperature of a given system or space. Depending on the type of device, this may be done through a thermocouple, thermistor, or other temperature detection method. The device will then control the temperature of the system using a variety of techniques, such as turning on or off a heater or cooling system, or adjusting the speed of a fan. The device will also adjust the power levels of the system in order to reach the desired temperature.

The 1645613-2 specification provides detailed information on the fields of application and working principles of non-programmable temperature controllers and thermostats. In particular, the specification provides detailed information on the requirements of temperature controllers, such as the accuracy, power supply requirements, and safety concerns. It also provides detailed information on the operation of temperature controllers, such as the control strategies and the programming requirements.

The 1645613-2 specification is an important tool for ensuring safety and helping to ensure that temperature controllers are used properly and effectively. It provides guidance on how to accurately measure, monitor, and control temperatures, including how to select the appropriate controls and program them for the desired results. It also provides guidance on how to properly install a controller and how to troubleshoot any problems that arise.
