How To Operate The AutoIQ Controller
The AutoIQ Controller is a microprocessor based
device 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
1. Freeze Button. Pushing and releasing this
button starts or restarts the machine. The
Controller remembers what cycle it was last in and
returns to that cycle.
2. 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
Harvest cycle.
3. Clean Button: Pushing and releasing this
button will cause the machine to empty the
reservoir, refill and leave only the water pump on
for circulation of ice machine cleaner. After the ice
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.
4. Off Button: Pushing and releasing this button
will switch the machine OFF at the end of the next
cycle. If the button is pushed and HELD for more
than 3 seconds, the unit will switch off
immediately.
To Reset Machine (machine off, error light on):
First push and release the Off button, then push
and release the Freeze button.
