1.3. Installation of temperature sensors
Handle the temperature sensors carefully! The sensor cables are fitted with coloured type labels:
• Red (TH): sensor in supply pipe
• Blue (TC): sensor in return pipe
Make sure the sensors are mounted symmetrically (both directly immersed, or both installed in a pocket).
The maximum cable length is 10m. The connecting cables must not be shortened or extended. The free
temperature sensors can be installed in a ball valve or adapter or in a conformity tested pocket for this type
of sensor. Ensure that the temperature sensors are permanently connected during operation.
For installation in a ball valve or adapter, a 4-piece coupling set is enclosed in a separate bag. See procedure
under item 1…5 on the right. Insert an O-ring in the sensor hole using the mounting pin supplied.
If the sensor is installed in a pocket, it must be inserted as far as the bottom of the pocket and then secured.
The pockets are best installed in T-pieces with a 45° or 90° angle. The tip of the pocket must point in the op-
posite direction to the direction of flow and must be located in the middle of the pipe. Temperature sensors
must be sealed after installation in the pockets.
The operation of any violation of this guidance will result in immediate invalidation of the factory
warranty and verification.
