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

•Loss Of Power

•Sensor Failure

•Clean Condenser

8- Display Features

•3-Digit LED Display

•Defrost in Progress Icon

•Fahrenheit or Celsius Temperature Scale In Use
