2.4.3.1 Adherence to the operating conditions acc. to MID for temperature sensors
The temperature sensors have to be installed symmetrically in the supply and return pipe and pref-
erably directly. In case temperature sensors with protection pocket are installed, the sensor and
the protection pocket have to be conformity-approved. The tips of the temperature sensors have to
be inserted up to the halt. Installation points in the flow sensor can be used in case the tempera-
ture sensor is installed symmetrically.
The connection cables of firmly connected temperature sensors must not be shortened.
The connection cables of replaceable and conformity-approved temperature sensors installed in
the supply and return pipe may be of a maximum length of 15 m; the cables must be of the same
length.
The cable cross section must be in line with EN 1434-2.
