- When the ICC receives a call for second
stage heating operation, “H” is displayed on the dual 7-segment LEDs.
“H” indicates second stage heating operation
55)) DDeeffrroosstt OOppeerraattiioonn
– When the ICC starts a defrost cycle, a lower case “d” is
displayed on the dual 7-segment LEDs.
Lower case “d” indicates defrost operation (in heating mode)

• 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 call for unit operation
is received.

• The 3-minute time delay can be bypassed when a call for compressor operation is
present by pressing the TEST button for 1 second and releasing. The compres-
sor will begin operation and the dual 7-segment will stop flashing.

• The ICC has a built in 30 second minimum unit run time. If a call for compressor
operation is received by the ICC and the call is removed, the compressor will con-
tinue to operate for 30 seconds. The dual 7-segment LEDs will flash “c”, “C”, “h”,
or “H” while the minimum run timer is active.
11 SSeeccoonndd CCoommpprreessssoorr//FFaann DDeellaayy
• The ICC starts/stops the outdoor fan one (1) second after the start/stop of the
compressor upon a call for compressor operation to minimize current inrush
and/or voltage drop.

Call for Compressor Operation (Y1 LED)
• If a call for compressor operation is received by the ICC (first stage/second stage cooling or
first stage/second stage heating), the red Y1 LED will illuminate.
• The ICC has an on/off fan delay of one (1) second for each stage of heating or cooling.
• The ICC ignores the lower pressure control for the first 90 seconds of compressor operation.
• On heat pumps, the ICC ignores the LPC during the defrost cycle.
• The 7-segment LED can display five (5) codes during a call for unit operation:
1) First Stage Cooling Operation – When the ICC receives a call for first stage cooling
operation, a lower case “c” is displayed on the 7-segment LEDs.
Lower case “c” indicates first stage cooling operation
2) Second Stage Cooling Operation – When the ICC receives a call for second stage
cooling operation, an upper case “C” is displayed on the 7-segment LEDs.
Upper case “C” indicates second stage cooling operation
3) First Stage Heating Operation - When the ICC receives a call for first stage heating
operation, “h1” is displayed on the 7-segment LEDs.
“h1” indicates first stage heating operation
4) Second Stage Heating Operation - When the ICC receives a call for second stage
heating operation, “h2” is displayed on the 7-segment LEDs.

“h2” indicates second stage heating operation
5) Defrost Operation – When the ICC starts a defrost cycle, a lower case “d” is displayed
on the 7-segment LEDs.
Lower case “d” indicates defrost operation (in heating mode)
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. The 7-segment LEDs will flash “c”, “C”, “h1”, or “h2
while the short cycle timer is active and a call for unit operation is received.
