• ine voltage must be present at the I
for the
compressor and the outdoor fan to operate
• The I
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 EcoNet 2-Stage Control™ enabled
thermostat.
Command for Compressor Operation
• If a command for compressor operation is received
by the ICC (first stage/second stage cooling or first
stage/second stage heating)
• The I
has an on off fan delay of one 1 second for
each stage of heating or cooling.
• The I
ignores the low pressure control for the first
90 seconds of compressor operation.
• The dual -segment
D displays five 5 operational
status codes.
1) First Stage Cooling Operation –
When the
ICC receives a command for first stage cooling
operation, a lower case c is displayed on the
dual 7-segment LEDs.
2) Second Stage Cooling Operation –
When the
ICC receives a command for second stage
cooling operation, an upper case
is displayed
on the dual 7-segment LEDs.
3-minute Anti-Short Cycle Timer
• The I
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 or
while the short cycle timer is active
and a command for unit operation is received.
• The 3-minute time delay can be bypassed when a
command for compressor operation is present by
pressing the UP button. The compressor will begin
operation and the dual 7-segment will stop flashing.
30 Second Minimum Run Timer
• The I
has a built in 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. The dual
-segment
Ds will flash c or
while the
minimum run timer is active.
3ECOND#OMPRESSOR&AN$ELAY
• The I
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.
