the threshold exceeded (upper or lower) flashes.
At the end of the time delay, if the temperature is still beyond one of the preset thresholds, the corresponding output relay opens and the yellow LED corresponding to the threshold exceeded is
extinguished.
The output relay closes instantaneously (at about the response time for disappearance of a fault) when the temperature returns within the window of the two preset thresholds on the front face
plus (or minus) the fixed hysteresis.
If the PT100 probe is wired incorrectly (missing or short-circuited) the output relays open and all 3 LEDs flash.
