VII. MICROPROCESSOR CONTROL

Your new refrigerator or freezer cabinet is equipped with a state-of-the-art microprocessor control, which precisely regulates operation and provides alarms when problems occur. It is supplied from the factory completely ready for use and requires no adjustments, but without the audible alarms activated. See pages 6 thru 16 for more information.

MICROPROCESSOR CONTROL

VII. a - CONTROL FEATURES: 1- Internal Time Clock

Eliminates external defrost time clock.

Defrost cycle can be quickly adjusted to suit individual location and use.

Must be set at power-up. (See page 11, “Setting the 24-Hour Clock”)

Will automatically update for Daylight Savings Time.

2- Water Resistant Housing - The face of the control is water resistant to provide for protection during cleaning. 3- Parameter/Service Levels

See “Customer / Service Parameters” on Page 9.

4- Defrost Lockouts - See “Setting Defrost Lockouts” on page 14.

Customers can set up to 4 different defrost lockout periods. The lockout prevents the unit from going into a defrost cycle during peak kitchen use. Note: The 24-hour clock must be set for this feature to operate correctly.

5- Communication Ability - A NAFEM Data Protocol (NDP) compliant RS-485 serial communications port is available to interface with data collection software (by others). All microprocessor control equipped models are capable of com- municating within a NAFEM Data Protocol network if provided with an optional Gateway Hub (available from Traulsen). The actual communications software is available from a number of third party software vendors.

6- Anti-Condensate Door Perimeter Heater Control

The “No-Sweat” feature is an energy savings system that allows the customer to adjust the percent of time for the door/ drawer heater to be “On” as needed for the prevailing ambient conditions (from 0 - 100% of the time each day). It is used to prevent condensation from forming around the perimeter of the drawers. The factory default setting is 100%. Adjust this set point down to a point just before condensation forms to save energy.

7- Alarms (See the following pages for explanations)

High Cabinet Air Temperature

Low Cabinet Air Temperature
