6.2. Temperature sensor connection
- Connect the sensor wires to terminals '1 and 2': the polarity is not relevant.
- Length of the sensor cables can be increased by user himself to up to 200 meters, using a PP 2x24
AWG cable.
- For immersion in water, use a thermowell (Image VI - item 13), available in the Full Gauge Controls
product line (sold separately).
