GENERAL DESCRIPTION
This product specification establishes the requirements for a combined control capable of controlling the
following products:
!
Hot Dog Roller Grill - The unit controls time & temperature in two (2) zones of a roller grill for a
preheat function, a HEAT function for a specified time at a higher temperature, and an automatic
switch at a preset time to a lower HOLD temperature. A daughter board attachment allows heating a
bun compartment and a Power Limit Technology insures units with bun warmers don’t exceed a
maximum current draw. And a special transition from HEAT to HOLD prevents rapid cool-down of
product during the transition.
HOT DOG GRILL CONTROL
!
Control Concept - Hot Dog - When the DIP-switch is selected for Hot Dog, the control consists of
the control plus two (2) output boards. The output boards are selected based on the electrical load.
If a bun warmer is attached, then an additional output board is required.
