    6 Settings Self-monitoring on the STB and STW (STB) NOTE! If the measuring system fails, i.e. if the expansion liquid has leaked, then the pressure under the dia- phragm drops and the circuit is permanently open. It is no longer possible to reset the system. The electrical circuit opens when cooling the probe of STW (STB) and STB down to the negative tem- perature range, but it then closes again if the temperature rises.
