Advice regarding the installation of temperature sensors:
► Only original factory equipped NTC10K,B=3950 temperature sensors are approved for using with tank,

it is equipped with 20m PVC cable, and the cable is temperature resistant up to 105C,

connect the temperature sensors to the corresponding terminals with either polarity.
► All sensor cables carry low voltage, and to avoid inductive effects,

must not be laid close to 230 volt or 400 volt cables (minimum separation of 100mm).
► Sensor cables may be extended to a maximum length of ca. 100 meter,

when cable’s length is up to 50m, and then 0.75mm2 cable should be used.

When cable’s length is up to 100m, and then 1.5mm2 cables should be used.
