7.13 Safety temperature limiter

This device is equipped with a safety temperature limiter which is independent
from the regulation or the control system and which switches off the control of the
heating security system if the safety temperature is exceeded (max. 130°C).
The limiter works on the principle of expansion of liquids in case of overheating
Make sure that the distributing main to the limiter is not bent or otherwise
damaged when the heating element is exchanged and whenever works are carried
out at the stabilizer.
