Temperature vs. Resistance Data
The SunTouch
®
Control System use 10k Ohm thermistor sensors. When the solar sensor is disconnected
from the SunTouch Control System, the sensor will read 10k Ohm at 77º F (25ºC). Refer to the
following table for the resistance at other temperatures. An accurate reading should give a temperature
setting that is accurate
