The product is used in conjunction with an external PTC thermistor which are typically embedded in motors. It will monitor the resistance of the thermistor and if this increases above the fixed threshold (due to an increase in measured temperature), the relay will de-energise. The resistance must decrease below the “release” threshold before the relay re-energises again.
