4.7.2 Connection of 4-Wire Temperature Sensors
For installations with cable lengths over 3 m or with unequal cable lengths, we recommend
the use of 4-wire temperature sensors. The maximum cable length of the 4-wire tempera-
ture sensors is 50 m.
The connection cable must have four wires with a cross-section of at least 0,5 mm

The insulation of the temperature sensor cables can be PVC or silicone. Sontex recommends
the use of silicone insulation.
