THE ELECTRONIC TEMPERATURE CONTROLLERS

2075DWRR

•The controller has a four minute minimum off-cycle regardless of the thermistor status.

•The controller has a 4° differential built into it for the refrigerator thermistor. When it senses 38°F, the refrigerator will cool until the thermistor senses 36°F, and will not re-initiate cooling until the thermis- tor senses 40°F. When monitoring actual temperature, by pressing WARMER temporarily, the refrigera- tion cycle may be off, when the temperature is a degree warmer than the set point, or the refrigeration cycle on, when it is a degree below the set point.

•The LED status indicator lights indicate compartment temperature is displayed and open thermistor. A solid light on, in LED position (1), means compartment temperature is displayed. A flashing light, in LED position (2), means open thermistor. (The thermistor has failed or has been out of limits.) If a refrigerator thermistor fails, the refrigerator will shut down. A thermistor would normally fail by open- ing (no continuity), or by shorting (no resistance).

•Under most conditions, the refrigerator will remain frost-free by clearing itself between refrigeration cycles. Because there is no thermostat bulb on the evaporator, like other U-Line refrigerators, the con- troller runs a 45 minute off-cycle for every 12 hours of clock time. The refrigerator will not cool during this off-cycle even if the refrigerator thermistor is calling for cooling.

•The entire control system is mounted in a single housing in the top drawer.
