  • Page 21: Showroom Mode

    Electronic Control System Integrated Series (700- BASE) Showroom Mode Showroom Mode was incorporated into the electronic control system so that units could be displayed in a showroom setting. When in Showroom Mode, all cooling functions are disabled, but the lighting system and LCD remain active.

  • Page 22: Functions Of Electronic Control System

    Electronic Control System Integrated Series (700- BASE) FUNCTIONS OF ELECTRONIC CONTROL SYSTEM The following few pages explain monitoring, regulating and controlling functions of the electronic control system. Display Zone Temperatures The temperature signals from the thermistors in the refrigerator and freezer compartments are monitored by the microprocessor and then displayed on the LCD.

  • Page 23: Regulate Freezer Zone Temperature (Bc/Bf)

    Electronic Control System Integrated Series (700- BASE) Regulate Freezer Zone Temperature (700BCI-3, 700BFI-3) When the thermistor in the freezer compartment reaches high off-set temperature, calling for cooling, the compres- sor and condenser fan are energized, but the evaporator fan is not allowed to run until the thermistor on the evapo- rator reaches 35°F (2°C).

  • Page 24: Regulate Refrigerator Zone Temperature (Bc)

    Electronic Control System Integrated Series (700- BASE) Regulate Refrigerator Zone Temperature (700BCI-3) When the thermistor in refrigerator compartment reaches high off-set temperature, calling for cooling, the refrigerator compartment fan is energized and microprocessor sends an 18 Volt pulse signal to the air baffle control to open, regardless of operational state of the compressor.
  • Page 25 Electronic Control System Integrated Series (700- BASE) Regulate Refrigerator Zone Temperature (700BR-3) When the thermistor in the refrigerator compartment reaches high off-set temperature, calling for cooling, the evapo- rator fan is energized, but the compressor and condenser fan are not allowed to run until the thermistor on the evap- orator reaches 38°F (3°C).
  • Page 26 Electronic Control System Integrated Series (700- BASE) Monitor and Control “Adaptive Defrost” (700BCI-3, 700BFI-3) Initially, the compressor will cycle-run for 12 hours, after which the microprocessor sends a signal to the defrost relay on the control board to close. This supplies power to the defrost heater, drain tube heater and fill tube heater. At the same time the compressor, condenser fan and evaporator fan are switched off.
  • Page 27 Electronic Control System Integrated Series (700- BASE) Monitor and Control Refrigerator Fan-Assisted, Off-Cycle Defrost (700BR-3) Temperature signals from refrigerator evaporator's thermistor’s are observed by the microprocessor. During off cycle defrost, if a refrigerator zone temperature reaches high offset (calling for cooling) before evaporator temperature rises to 38°F (3°C), no power will be supplied the the compressor.
  • Page 28 Electronic Control System Integrated Series (700- BASE) Monitor Compressor Run Duration, Displays If Service is Needed The microprocessor observes the state of the compressor relay to determine the length of compressor run time (See Figure 3-22). If the compressor runs 100% (Freezer = 6 hours, Refrigerator = 4 hours), an error code is logged (EC 40), and defrost will be initiated, but SERVICE will not flash.
  • Page 29 Electronic Control System Integrated Series (700- BASE) Monitor Icemaker System and Display If Service is Needed The microprocessor observes the power supplied to the icemaker water valve solenoid. If the solenoid is energized for more than 15 seconds, power to the icemaker system is disabled for 24 hours and an error code is logged (EC 30).

    Electronic Control System Integrated Series (700- BASE) If Error Codes are observed in Diagnostic Mode, a non-flashing SERVICE icon will appear on the LCD when Diagnostic Mode ends, indicating error codes are still stored (See Figure 3-39). To clear a non-flashing SERVICE icon and the error codes, the problem must be corrected and the unit must be ON, then the door ajar alarm bell ON/OFF key must be pressed and held for 15 seconds.

  • Page 34: Temperature Log Recall Mode

    Electronic Control System Integrated Series (700- BASE) Temperature Log Recall Mode The electronic control system is equipped with a temperature history data storage system. This system logs/stores the average temperature of each individual thermistor every two hours, along with any event indicators (explained later in this section), that may have occurred.
