• The ICC has a built in 3-minute time delay between compressor operations to
protect the compressor against short cycling. The dual 7-segment LEDs will flash
“c”, “C”, “h”, or “H” while the short cycle timer is active and a command for unit
operation is received.

•
The ICC has a built in 3-minute time delay between compressor operations to protect the
compressor against short cycling. The 7-segment LEDs will flash “c”, “C”, “h1”, or “h2
while the short cycle timer is active and a command for unit operation is received.

Flashing upper case C
A command for second stage cooling has be received
Flashing lower case h and 1
A command for first stage heating has been received
Flashing lower case h and 2
A command for second stage heating has been received
•
The 3-minute time delay can be bypassed when a command for compressor operation is
present by pressing the TEST button for 1 second and releasing. The compressor will begin
operation and the 7-segment will stop flashing.
30 Second Minimum Run Timer
•
The ICC has a built in 30 second minimum unit run time. If a command for compressor
operation is received by the ICC and the command is removed, the compressor will continue
to operate for 30 seconds. The 7-segment LEDs will flash “c”, “C”, “h1”, or “h2
while the
minimum run timer is active.
1 Second Compressor/Fan Delay
•
The ICC starts/stops the outdoor fan one (1) second after the start/stop of the compressor
upon a command for compressor operation to minimize current inrush and/or voltage drop.
