FLUSHMOUNT SENSOR (WM PART # OE210)

ANALOG INPUT SCALING - From Sat Analog Input Screen

Description:

Type: Thermistor

Pattern for values associated with this input: xxx.x

Degree Type: F Units of measure message#: 1

Filter time constant: 0 Seconds

Input Jumper must be set to THERM
There are berg jumpers that are under the SAT III cover that must be set.
JOX corresponds to X = 1 to 8 for the Analog Input jumper.
Example:
JO1 is for Analog Input #1
JO8 is for Analog Input #8

An Input Load Resistor must not be used. Internally, the SAT III

controller calculates the resistance of the thermistor back to a Voltage so
that the SAT III controller can calculate the proper temperature. RX
corresponds to X = 1 to 8 for the Analog Input load resistor. Example as
follows:
R1 is for Analog Input #1 (NO RESISTOR SHOULD BE INSTALLED)
R8 is for Analog Input #8 (NO RESISTOR SHOULD BE INSTALLED)
Testing with an Ohmmeter:
Disconnected from the SAT III controller, measure from TMP to GND
on the sensor. You should get an ohm meter measurement that
corresponds to the Temperature. 10,000 ohms equals 77.0 DegF
