TEMPERATURE SENSOR box
This shows the present temperature of the control sensor and the secondary sensor.
The menu options allow for selecting which temperature‐resistance curve the controller is to reference for
reporting the present temperatures of the thermistors. The 15K sensor type should be selected if using the
MP‐3193, MP‐2444, or MP‐2542 thermistor.
The 15K sensor provides an effective control range of ‐20 °C to +100 °C.
The 10K sensor provides for an effective control range of ‐20 °C to +85 °C. The temperature‐resistance curve for
the 10K sensor is the same as curve “B” from YSI Temperature, Inc. See “Temperature versus Resistance” below
for further details on the 15K and 10K data.
If you are using two thermistors, they must have the same resistance versus temperature
characteristics. Also be sure that you have selected the correct sensor type. Otherwise a dangerous
condition could exist because the actual temperature could be higher or lower than the temperature
being interpreted by the controller.
