6.5.2 Installation of temperature sensor
If the operating logic requires the installation of a temperature sensor in the system, the Manufacturer supplies the neces
-
sary kit to be assembled by the fitter.
The kit consists of:
-
1 threaded probe pocket G1/2";
- 1 temperature sensor.
Fig. 15 Components of the kit
The kit is supplied pre-assembled inside the electrical control panel and electrically connected to the termi-
nal board.
Components must be fitted on the system as illustrated in the hydraulic diagram of the corresponding operating logic.
A G1/2” sleeve (out of supply scope) is required for temperature sensor installation.
Install the sleeve so that the pocket and the probe are in vertical position and not exposed to accidental damage.
The length of the sleeve to be used depends on the pipe diameter.

Fig. 16 Installation of pockets
Fit the pocket in position and check that distance “h” ranges between 1/4 and 3/4 the pipe diameter “Ø”.
Secure the pocket to the sleeve using a special sealant to create leak tight conditions.
To ensure proper reading, coat the entire length with heat conducting paste before fitting the sensor.
Heat conducting paste ensures optimised temperature probe reading.
Connect the sensor to the terminal board, as shown in the wiring diagram of the unit.
It may be necessary to extend the cables.
If the cables are extended, this must be done professionally to ensure a good electrical connection and protection from
moisture over time.
We recommend that the sleeve in which the pocket is fitted is fully isolated.
After the sensor has been installed, make sure it is protected against accidental damage and the connection
cable is secured properly.
After completing the thermal insulation of the hydraulic circuit, secure the cable properly.
