VII.  MICROPROCESSOR CONTROL

Your new 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 adjust-
ments, but without the audible alarms activated.  See pages 6 thru 16 for more information on the microprocessor 
control.

II. 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 Access Code on Page 8 / 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 collec-
tion software (by others).  

All microprocessor control equipped models are capable of communicating 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.
