SECTION 8.
Brute Elite Control Setup
and Operation
The Brute Elite control is an integrated electronic control that replaces many of the individual components found on older appliances. The control acts as the ignition control, pump control, high limit and cascading/ lead lag control and is setup using the display on the appliance.
Once the value is adjusted the NEXT or DONE button can be pressed. The DONE button returns you to the Home screen. The NEXT button increments the display to the next item in the menu structure.
USER mode is the home screen shown on the control. If the display is not in USER mode wait for the display timeout period to be reached or press the Done button to return to the USER menu.
SETUP mode is accessed by holding the up and down arrow keys simultaneously for 3 seconds.
DIAGNOSTIC mode is accessed by holding the NEXT button for 3 seconds.
