Water supply
15
Additional icemaking
water supply time
Time to supply additional icemaking water
required after pump motor starts following
normal icemaking water supply time (it is
deactivated on this model).
17
Defrosting water control
Selection of defrosting water control. When
set to “0”, normal control as described for No.
11 above. When set to “1”, control timing is
segmented into two.
18
Defrost completion temp
correction
Set defrost completion temp correction value
when defrosting water control setting is
changed.
Others
21
Double stack bin control
Selection of bin control in case of double stack
application.
22
Refrigeration unit
operation in bin control
cycle
Selection of control to prevent ice in storage bin
from melting in bin control cycle (by operating
refrigeration unit).
Model
30
Type
Selection of fan motor type. When set to “0”, unit
operates as water-cooled model.
Defrost cycle low
temp control
34
Operating temp
Set temp for continuous fan motor operation in
defrost cycle to lower temp inside control box if
ambient temp at the beginning of defrost cycle
exceeds set point.
Water regulator
36
Water regulator error
detecting temp
Thermistor temp (water regulator outlet) in case
of water regulator error and cooling water failure
for water-cooled model.
Compressor
37
Compressor output
selection
Selection between AC supply and DC supply
(normal setting = AC supply). Transformer
voltage drop is too large to input both.
Slush ice
50
Pump off time
Pump off time for slush ice control to stop pump
after 2 min (controller board P01873-01) or 30
sec (P01873-02) at evaporator temp of 3 to 4°C,
quickly refrigerate evaporator before icemaking
water supercools, and form ice core. When set
to “0”, there is no slush ice control.
51
Water supply time
Time to supply water while pump is off for slush
ice control. If slush ice is too much and cannot
be prevented solely by pump off in No. 50, water
is supplied while pump is off to slightly raise tank
water temp.
Hard water
60
Operating condition
Condition to operate cloudy ice control in hard
water application indicated in percentage
against target integrated value. After icemaking
water supply starts, ice begins to form, and
freeze cycle integrated value reaches a certain
level. Then, additional water is supplied to dilute
concentrated icemaking water in water tank.
61
Water supply time
Time to supply water for hard water control.
Ice left in water
pan
70
Operating temp
Upper limit of operating temp to control ice left in
water pan at the end of freeze cycle. Decrease
amount of defrosting water by reducing ice left
in opening water pan after freeze cycle.
71
Hot gas valve on time
Hot gas valve opening time to control ice left in
water pan.
72
Hot gas valve off time
Hot gas valve closing time to control ice left in
water pan.
