Temperature Control Operation
For any temperature setting, outputs will be turned off/on based on cut-in/cut-out
temperature determined by resistance levels of freezer or refrigerator thermistors
Refrigerator and Freezer Thermistor
As temperature decreases, resistance increases.
As temperature increased, resistance decreases.
NOTE: Open thermistor or thermistor circuit will result in failure of unit to cool. Shorted
thermistor will cause unit to run 100 percent of time except during defrost cycle.
•
.Unit temperature setting and thermistor value will determine if
compressor/condenser fan and evaporator fan switches are open or closed.
Compressor/condenser fan switch must be open for 6 minutes before switch can
close again (compressor dwell time).
•
Cut-in and cut-out temperature values must be reached and maintained for 15
seconds in All Freezer and 30 seconds in All Refrigerator before output will
change (digital delay).
•
Unit control calibration can be adjusted in Program Mode B.
