3- Installation
The controller should be installed in a place protected from vibrations, water and corrosive
gases, and where ambient temperature does not surpass the value specified in the
technical data.
In order to give a correct reading, the probe should be installed in a place without heat
influences other than the temperature that is to be measured or controlled
