Enter the factory program mode by first entering the programming mode then
pressing the power and fan buttons simultaneously. Use the mode button to
move forward and the Temp select button to scroll back through the factory
program items. Once in the factory mode the following program changes can be
made:
F-1: Voltage Calibration
The systems volt meter can be adjusted plus or minus 10 volts AC. Use this item
to calibrate the voltmeter.
F-2: Calibrate the Current Meter
The systems current meter can be adjusted plus or minus 10 amps. This item is
used to calibrate the systems current meter.
F-3: Compressor Run Time Low Range
The compressor run time can be reset should the compressor have to be replaced.
F-3 covers the range 1 through 999 hours run time.
F-4: Compressor Run Time High Range
F-4 is used to reset compressor run times from 999 through 10,000 hours. Ten
thousand hours would be displayed 10.0 in the display window.
F-5: Short Circuit Test
The short circuit test is normally Off, however, while the unit is being installed
the short circuit test can be turned On. Once the system is installed and no short
circuits are detected the Short Circuit Test should be turned Off. Turning off the
test will speed the cold boot-up time from the AC power off condition.
F-7: Reserved For Future Use
F-7 is a blank memory location reserved for future use.
F-6: Compressor Load Fault Message (CLF) Normally On
Compressor load fault (CLF) occurs when the KLIXON or high head pressure switch
opens causing an interruption of power to the compressor. Typical causes would be loss
of cooling water or high Freon head pressure. The CLF can be turned off during trouble
shooting sessions but should be turned on for normal operation.
F-8: Start Cap Relay Supervisory Circuit (SCR)
The operation of the systems start capacitor and relay are monitored and the
compressor is shut down if either item fails. A sticking or failed start component will
cause the compressor to fail. Shutting down the compressor and flashing SCR saves
unnecessary compressor burnouts. SCR is NORMALLY ON and can be tempo-
rarily turned off for trouble shooting, however, SCR should be turned on after
the problem is resolved.
