Temperature/Resistance /Voltage
All Hayward controls use a 10K thermistor sensors. When disconnected from the
control, the sensor will read 10K ohms at 25ºC/77ºF. Refer to the chart below for
the resistance at other temperatures. For a given temperature, the resistance
reading should be accurate to ±1%. For a given resistance reading, the tempera-
ture reading should be accurate to ±0.5ºF. All voltage measurements (DC) must
be made with the sensor connected to the control and should be accurate to ± 2%.
