TE Technology TC-720 - Manual (Page 38)

2.4.15 SENSOR 1, SENSOR 2 TYPE
Values: 15K-1, 10K-2, 10K-1, 5K-1, User Defined, 230K-1, or 50K-1
Default value = 15K-1
Description:
15K-1 should be selected when using the supplied MP-3193 thermistor or other thermistors with equivalent
temperature-resistance curves. See Appendix for further details.
The other thermistors curves should be selected when using thermistors having curves as shown in the Appendix.
A User Defined sensor can be used when the controller is to be used with an IC-type sensor or a non-programmed
thermistor, for example. This requires a table of values to be programmed into the controller via computer though.
Additional details are available in the software section of the manual below.
Depending on the sensor type being used, the CONTROL RANGE may need to be adjusted as well.
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.
2.4.16 LOAD DEFAULTS
Description: Reprograms all settings in the controller to the factory defaults.
Pressing the down key and allowing the menu timer to time out on the YES selection will cause the controller to
display another message instructing the user to hold the “menu key” and “up key” for 3 seconds to load the
default values. See flow chart 2 for operation.
