that receives input from several sources and
switches various components on and off.
Its manual control is thru the use of the Push
Button Control Switches

Pushing and releasing this
button starts or restarts the machine. The AutoIQ
Controller remembers what cycle it was last in and
returns to that cycle.

Harvest Button:
Pushing and releasing this
button will cause the machine to go directly to a
Harvest Cycle. Can be done from Freeze or Off.
The machine will switch Off at the end of the

Pushing and releasing this
button will cause the machine to empty the
reservoir, refill and leave only the water pump on

machine cleaner has circulated for about 10
minutes a second push of this button will switch on
the rinsing system to flush out the dissolved scale
and ice machine cleaner.
