Rheem ARL-JEZ 16 Seer Series, Installation Instructions Manual, Page: 23 / 40

23
• Y2 – Call for unit second stage operation (cooling)
Low Volt Fuse
• If required replace with 3 A automotive ATC style blade fuse
Low Pressure Control (LPC Input – E14)
• Low-pressure control is factory installed
• Low pressure control is an automatic resetting device
High Pressure Control (HPC Input – E14)
• High-pressure control is factory installed
• High pressure control is an automatic resetting device
Compressor Solenoid Output (E14)
• Compressor solenoid output is controlled by the control for second stage cooling
operation.
Ambient Temperature Sensor
• Included on control but not required in the cooling only condenser application
TEST and SW2 Buttons
• TEST and SW2 buttons used to enter Test and Fault Recall Mode
ICC CONTROL OPERATION
Installation Verification
• 24V AC power on R and C must be present at the ICC for it to operate
• Line voltage must be present at the ICC for the compressor and the outdoor fan
to operate
• When line and 24VAC control voltage is present and there is no Y1 call, or other
diagnostics displayed, the control will display an “O” for standby mode
• If a Y1 call is initiated within 3 minutes of unit power-up or last compressor activa-
tion the control will display a flashing “c” and the red Led will activate to solid on
Call for Operation (Y1 Call)
• The ICC has an on/off fan delay of one (1) second.
• The ICC ignores state of LPC for 90 seconds upon compressor start
• The ICC will cause the compressor to be energized for 30 seconds minimum run
time except when TEST button is pushed without a Y1 call
Call for Operation (Y2 Call)
• 5 sec delay from Y1 to Y2
• 1 minute recycle when Y2 call ends
• The control will not allow the 2 stage solenoid to be energized for 1 minute after
the solenoid has been deenergized.
3-minute Anti-short Cycle Timer
• The ICC has a built in 3-minute time delay between compressor operations to
protect the compressor against short cycling (Status flashing c).
• The 3-minute time delay can be bypassed when a Y1 call is present by pressing
the TEST button for 1 second and releasing (Status solid on c).
30 Second Minimum Run Timer
• The ICC has a built in 30 second minimum unit run time (Status flashing c).
1 Second Compressor/Fan Delay
• The ICC starts/stops the outdoor fan 1 second after the start/stop of the compres-
sor upon a Y1 call to minimize current inrush and/or voltage droop.
Low Pressure Control (LPC)
• Upon a Y1 call, if the ICC senses an open LPC it will not allow the compressor to
be energized (diagnostic code 21).
