Freeze Mode: (Ice-Making)
Note:
If the water level drops below the sensor
before 5 minutes, the control counts a Hung Slab.
If the water level sensor is not detected, the control
sets a 25-minute freeze time.
Time in this mode is dependent on the water
level in the reservoir. There is no minimum time.
The maximum time is 25 minutes. Compressor,
condenser fan, and recirculation pump are all
energized.
Water continues to recirculate until the water level
in the reservoir drops below a level determined by
the water level sensor. At this point, the control
terminates the freeze mode and initiates the
Harvest Mode.

Harvest Mode
The time in this mode will be 2 to 17 minutes,
dependent on the condition of the evaporator
thermistor.
The compressor and hot gas valve is on for a
minimum of 1 minute.
Note:
There is a 4-min.

thermistor is unplugged or open.
Harvest Mode: Bin Full
The time in this mode with the bin full will be a
minimum of 5 minutes. The mode continues as long
as the bin is full and the bin thermistor remains less
than 36°F.
Compressor and hot gas valve are on until the
evaporator thermistor is greater than 52°F and more
than 1 minute but less 16 minutes have passed;
or after 4 minutes if the evaporator thermistor is
unplugged or open.
Idle Mode:
Time in this mode is dependent on the temperature
at the bin thermistor.
Bin Not Full (Bin Thermistor Greater than 36°F)
The control sends a reservoir
