4.2 External temperature probe
Depending on how it is configured, the external temperature probe can be used to accomplish several
functions (see 7.6); it does NOT have polarity so you can connect the 2 wires in the 2 terminals without
any particular order.
It is recommended to use the NTC 10k beta 3900 probe (art. 02965) that provides double insulation.
The typical wiring diagram is the following:
