Sensor Error Raypak RP2100

[JPhmm]

Sensor Error on a Raypak RP2100, my understanding is this is caused by a 2 degree difference,
I've seen where disconnecting the sensor (power off) for 5 minutes will clear the error,
I tried that and it did not correct the error - however, I pulled the sensor (side of heater) and reseated it,
and also depressed the SW1 switch on the board - this seems to have corrected the issue but I'm trying to
verify what the function of the SW1 switch is? Any insight?

Sensor error, fortunately, is usually one side of the temperature sensor reading too far from the other. Better than the whole board being bad. You can chase it and get frustrated or just change the sensor for about $20.00 (aftermarket ones work well).
