Piper ICE-60 - Manual (Page 5)

ICE and ICF - Electronic Control
Control Functions:
-Displays temperature equal to average product temperature
-Controls condensing unit to achieve desired temperature
-Cycles evaporator fans on at all times except during defrost cycle
-Controls the start and finish of defrost and energizes defrost solenoid
-Indicates on display whether compressor defrost solenoid or fans are energized
Adjusting temperature in pre-set range:
-Pressing the "SET" button twice will display the current set point
-Use the UP or DOWN arrow to adjust to desired temperature
-Press the "SET" button again to accept new set temperature
Changing factory set control parameters:
To access the following list of settings you just depress the "DOWN" arrow and the
"F" at the same time at which time "DIF" will be displayed. The "F" button is
pressed repeatedly to scroll through the settings listed below, each of the values
can be changed by pressing the "DOWN" and "UP" arrow keys. For any changes
which were made to be accepted by the control you must scroll through the entire
list until a blank screen is shown for a few seconds and then the current temperature
is again displayed.
Settings for Production Units:
DIF -02 differential or amount temperature can fluctuate
HI 2° F high point of temperature adjustment range
LO -20° F low point of temperature adjustment range
CAL -04° F amount displayed temperature offset from actual sensor
DEF.INIT. 02 hrs. time between initiation of defrost cycles
DEF.DUR. 06 min. maximum duration of defrost cycle
DEF>HI 70° F temperature at which coil sensor will terminate defrost
SHO CYC 02 min. the minimum number of minutes compressor is off
FAN HI 10° F coil temperature above which evaporation fans will not run
COIL SEN displays evaporator coil outlet tubing temperature
Operation Notes:
On power-up there will be a click of control energizing relays, then a two-minute delay for
the start of the compressor.
To initiate a defrost after unit has cooled down, unplug momentarily and defrost will start
when power is restored to unit, compressor may however still have a two-minute delay due
to short cycle control.
