Do not splice the wiring to extend or shorten it, or this could affect correct monitoring of each temperature.

If the wiring is too long, bundle it with a strap to adjust the length.

*1. The maximum length of the thermistor wiring is 5 m.

When the wires are wired to adjacent terminals, use ring terminals and insulate the wires.
