SAFETY THERMOSTAT STB WYF95PE-ZS4

PRODUCT DESCRIPTION

Heating devices operating in our homes or industrial plants are most often powered by electricity or steam generated by heating water in a special boiler. Energy supply can be continuous, but this would result in overheating the device and damaging it. A way to control the temperature is by installing sensors and thermostats, as well as a special safety system called STB.
The abbreviation STB is borrowed from the German technical term “Sicherheitstemperaturbegrenzer,” which translates as safety temperature limiter. Its purpose is to control the maximum temperature that the device can reach.
In technical jargon, it is referred to as an alarm, meaning a level that threatens overheating or even burning of components. The STB sensor level is set manually or at the factory, depending on the system.

Heating devices operating in our homes or industrial plants are most often powered by electricity or steam, generated by heating water in a special boiler. Energy supply can be continuous, but this would result in overheating the device and damaging it. A way to control temperature is by installing sensors and thermostats, as well as a special safety system called STB.

In technical jargon, it is referred to as an alarm, meaning a level that threatens overheating or even burning of components. The STB sensor level is set manually or at the factory, depending on the system.

In industrial boilers, the limit value is usually programmed according to standards for the given device. In domestic heating devices, such as bathroom boilers or flow heaters, the alarm temperature value is set independently using a dial.
The STB sensor is an electronic device powered electrically, which operates by opening contacts when the limit temperature is reached. Reclosing is not possible automatically even after the heat level decreases. The reset must be performed by an operator. This is usually done via a special button, but in some industrial devices, partial disassembly of the housing is required to reset.

There are also pressure STB temperature limiters that do not require external power supply. They are equipped with an additional valve, which is closed by an auxiliary spring if the capillary is damaged and fluid leaks, or if the limit temperature is exceeded. These types of regulators provide additional protection for heating devices in case of standard thermostat failure.
