Field Confi guration Jumper
Note: The JW1 fi eld confi guration jumper should be clipped
ONLY when power is removed from the ICC control.
Water Coil Low Temperature Limit Setting: Jumper 1 (JW1)
provides fi eld selection of the temperature limit setting for
FP1 of 30ºF or 10ºF [-1ºC or -12ºC] (refrigerant temperature).
Not Clipped = 30ºF [-1ºC]. Clipped = 10ºF [-12ºC].
Diagnostic Port
The diagnostic port E25 is for a diagnostic tool only. Do not
attempt to connect other components or use a telephone
cord. Damage will occur.
Memory Card
The memory card stores all of the unit confi guration
data, referred to as shared data. The shared data is the
information required for proper unit operation.
NOTE: The memory card for the unit has specifi c shared
data for this unit. The memory card is attached to the
control box with a tether.
Normal Control System Operation
Installation Verifi cation:
24VAC power on R & C must be present at the ICC control
and the Blower control for the system to operate properly.
Line voltage must be present for the compressor, blower,
and pumps to operate properly.
The ICC control displays a "0" for standby mode. Standby
mode indicates line voltage and 24VAC are present at the
ICC, and there is not a command for unit operation from the
serial communicating thermostat.
Zero (0) displayed indicates the unit is in standby
Command for Compressor Operation (Y1 LED)
If a command for compressor operation is received by the
ICC (fi rst stage/second stage cooling or fi rst stage/second
stage heating), the LED will illuminate.
The ICC has an on/off pump delay of one (1) second for each
stage of heating or cooling.
The Blower control has an on/off indoor blower delay for
heating and cooling.
The ICC ignores the low pressure control for the fi rst 120
seconds of compressor operation.
The ICC ignores the low temperature protection
temperatures for the fi rst 120 seconds of compressor
operation.
The dual 7-segment LED displays four (4) operational status
codes:
1) First Stage Cooling Operation – When the ICC receives a
command for fi rst stage cooling operation, a lower case
"c" is displayed on the dual 7-segment LED.
Lower case "c" indicates fi rst stage cooling operation.
2) Second Stage Cooling Operation – When the ICC
receives a command for second stage cooling operation,
an upper case "C" is displayed on the dual 7-segment
LED.
Upper case "C" indicates second stage cooling operation.
3) First Stage Heating Operation – When the ICC receives a
command for fi rst stage heating operation, a lower case
"h" is displayed on the dual 7-segment LED.
Lower case "h" indicates fi rst stage heating operation.
4) Second Stage Heating Operation – When the ICC
receives a command for second stage heating operation,
an upper case "H" is displayed on the dual 7-segment
LED.
Upper case "H" indicates second stage heating operation.
5-Minute Anti-Short Cycle Timer
The ICC has a built in 5-minute time delay between
compressor operations to protect the compressor against
short cycling. The dual 7-segment LEDs will fl ash "c",
"C", "h", or "H" while the short cycle timer is active and a
command for unit operation is received.
Flashing lower case "c" indicates a command for fi rst stage
cooling has been received.
Flashing upper case "C" indicates a command for second
stage cooling has been received.
Flashing lower case "h" indicates a command for fi rst stage
heating has been received.
