Calibrating the 14A00-8 Water Temperature Sensor and 1101A PESM

The temperature can be calibrated by using the potentiometer on the device. Turn the potentiometer clockwise to "lower" the temperature. Turn the potentiometer counter-clockwise to "raise" the temperature.

The system only updates the temperature every 30 seconds. For a proper reading, wait 60-90 seconds after making an adjustment to the potentiometer.

If you have a meter that reads frequency, the temperature (in frequency) can be read over a DC square wave. Put your meter between the black and yellow wire and measure the frequency.

FREQUENCY = (4 TEMPERATURE) / 30

Example:

If the ambient temperature is 75 degrees:

FREQUENCY = (4 75) / 30

FREQUENCY = 300 / 30

FREQUENCY = 10 Hz
