item will be selected. Once all items in the menu have
been displayed, the menu resumes from the beginning
until the button is released.

Program Unit Capacity/Size Mode
After the “P” is selected (by releasing the push button)
the integrated control will start flashing the “P” on display
for 90 seconds. If push button is pressed again and held
during that time, the control will start to display characters
