Clg State is a status only item which displays the current
compressor operating state when the unit is in the Cooling
operating state or when dehumidification operation is active.
See page 89 for compressor cooling operating state details .
Htg State (Heat Pump only) is a status only item which
displays the current compressor operating state when the unit
is in the Heating or Min DAT operating state .
for compressor heating operation state details .
INV Cmp Spd is a status only item which displays the current
inverter compressor speed in percent of the maximum .
INV Spd Cmd is a status only item that indicates the current
commanded speed of the inverter compressor .
Comp 3 is a status only item which displays the current on/off
status of the fixe compressor.
Prev Standby is a status only item which displays the most
recent abnormal event that caused the compressor Clg State
or Htg State to transition directly from the Normal to Standby
state . Pressing enter while viewing this item will display the
date and time of that event .
INV Port Temp is a status only item which displays the current
value of the calculated temperature (based on the current
suction pressure reading) at the inverter compressors inlet
port . This value is used in the inverter compressor discharge
line higher temperature limiting protection function .
INV Fin Temp is a status only item which displays the current
inverter compressor control board cooling fin temperature.
This value is used in the inverter compressor fin temperature
limiting protection function .
INV Cmp Amps is a status only item which displays the current
amperage being drawn by the inverter compressor . This value
is used in the inverter compressor current limiting protection
function .
PTD is a status only item which displays the current value of
the discharge line refrigerant pressure .
PTS is a status only item which displays the current value of
the suction line refrigerant pressure .
4 Way Valve (Heat Pump only) is a status only item which
displays the current Heat/Cool (Closed/Open) status of the
heat pump four way reversing valve .
RcvrSol Valve (Heat Pump only) is a status only item which
displays the current Open/Closed status of the heat pump
receiver solenoid valve .
BP Sol Valve is a status only item which displays the current
Open/Closed status of the refrigerant circuit bypass solenoid
valve . This valve is normally closed but opens when needed to
equalize the low and high side refrigerant pressures .

Clg Lo OAT Lk is an adjustable item which sets the low
outdoor air temperature mechanical cooling lockout point .
Mechanical cooling operation is disabled when the outdoor air
temperature sensor input falls below this set point .
Htg Lo OAT Lk is an adjustable item that sets a low outdoor
ambient temperature value below which compressor heating is
See page 118 locked out .
Htg Hi OAT Lk is an adjustable item that sets a high outdoor
ambient temperature value above which compressor heating is
locked out .
EffHtgOATLk is a status only item that displays the current
value that is being used for high outdoor ambient compressor
heating lock out . Normally this value reads the same as the Htg
Hi OAT Lk but can be lower due to the low differential pressure
limiting function while the unit is operating in the Heating or
MinDAT states .
OAT Diff is an adjustable item that sets at differential above
the Htg Lo OATLk and below the Htg Hi OATLk values for
determining when heating becomes re-enabled after being
locked out on outdoor ambient temperature .
INV Period is an adjustable item that sets the sample period
for the PI loop used to control the compressor capacity to
maintain the effective discharge air temperature set point .
INV Gain is an adjustable item that sets the Gain for the PI
loop used for the PI loop used to control the compressor
capacity to maintain the effective discharge air temperature set
point .
INV PAT is an adjustable item that sets the project ahead
time for the PI loop used for the PI loop used to control the
compressor capacity to maintain the effective discharge air
temperature set point .
INV Max Chg is an adjustable item that sets the maximum
change value for the PI loop used for the PI loop used to
control the compressor capacity to maintain the effective
discharge air temperature set point .
Clg Press Lmtg is a status only item which displays the current
compressor limiting function related to refrigerant pressure that is
active during cooling operation
Htg Press Lmtg (Heat Pump only) is a status only item which
displays the current compressor limiting function related to
refrigerant pressure that is active during heating operation
page
C Ratio Lmtg is a status only item which displays whether or
not the high compression ratio limiting function is active
page
Ref DTL Lmtg is a status only item which displays the current
refrigerant discharge line high temperature limiting function that
is active
