Installing the temperature sensors
!
The distance between the sensor cables and sources of electromagnetic interfe-
rence must be at least 300 mm
The outlet sensor is either integrated in the measuring capsule or it must be installed
in the connector. The inlet sensor is installed in a special ball valve or immersion pocket
released for this type of sensor. – This applies vice versa for the inlet variant.
