ELECTRONIC CONTROL BOARD
(NEW STYLE)
New Style Control Board
New Style Control Board Improvements
•
A dual voltage transformer means only one
control board for both 115V and 208-230V use.
•
One 7-amp fuse - no separate transformer fuse.
•
A single ice thickness probe provides improved
ice thickness control by eliminating the possibility
of scale or slime bridging the probes, causing
premature harvests.
•
A yellow “Clean” light energizes when a SeCS

or AuCS

cycle is in progress.
CAUTION
J model control boards that have only terminal 1C
(no terminal 1D on board), must use the new single
probe ice thickness control
•
An adjustable harvest cycle water purge can be
set to 15, 30 or 45 seconds. This will not affect
clean cycle purge time.
CAUTION
This control is factory-set to 45 seconds. A reduced
setting will increase cleaning frequency.
•
Safety limits 3 and 4 have been eliminated; no
thermistor is required.
•
Exact control board replacement when replacing
an old style control board with a new style control
board. Electrical sequence of operation is
identical to the old style control board.
