HES #2 is a three wire switch and can stop in three
separate failure modes.

ice machine will not start.
• HES #1 and HES #2 lights are de-energized, the
ice machine will not start.
• HES #1 and HES #2 are energized. The ice
machine starts, immediately shuts off and starts
another 5 minute delay period (control board lights
race to indicate 5 minute delay period). The ice
machine will repeat the sequence until the toggle
switch is moved to OFF or power is disconnected
to the ice machine.
In all failure modes disconnecting HES #2 from the
control board will result in Switch Fails Open or is
