6.8.1.2 Low Regulation Temperature - Lrt
This alarm is generated if the regulation sensor falls below the value (COO-A16)-r01 if the relative set points are used (A86 = 0), or A88-r01 if the abso-
lute set points are used (A86 = 1) for a time A17. It is cancelled when the regulation sensor reaches the value COO-A16 if the relative set points are used
(A86 = 0), or A88 if the absolute set points are used (A86 = 1). Warning only.
6.8.2 Filter Maintenance Warning - HFI
Theltermaintenancewarning(HFI)isdisplayedwheneverthenumberofhoursofoperationsetinparameterA91(PArmenu,PAalarms)isreached,
whichdenestheltermaintenanceinterval.
Thelterisanoptionalcomponent;ifthelterisnotinstalled,whentheltermaintenancewarningisdisplayeditwillbenecessarytocleanthecondenser
coil; see the use and maintenance manual C17000903.
The maintenance interval is factory set to 3000 hours (A91=300). Parameter A91 can be set from the PAr menu: the value entered is multiplied by 10 to
denethenumberofhoursofoperationbeforethemaintenancewarningisdisplayed(e.g.settingA91=1correspondstoanintervalof10hoursofopera-
tionofthelterbeforethemaintenancewarningisdisplayed).
Theltermaintenancewarningcanberesetbyresettingthelteroperatinghourscounter(OFi)bypressingandholdingtheUPbuttonfromthemain
screen (during the reset, the “ON/stand-by” icon will blink rapidly on the display for 2 seconds).
6.8.3 Maximum Pressure - HP1
Activatedwhenthemaximumpressureswitchintervenes,andthecompressorisshuto󰀨.
This alarm is resolved automatically when the pressure switch is reset, and the compressor is therefore restarted.
If the alarm reoccurs 3 times within the space of an hour, a manual reset will be necessary to restart the compressor (see sec. 6.8.10).
6.8.4 Minimum Pressure - HP1
Activatedwhentheminimumpressureswitchintervenes,andthecompressorisshuto󰀨.
This alarm is resolved automatically when the pressure switch is reset, and the compressor is therefore restarted.
If the alarm reoccurs 3 times within the space of an hour, a manual reset will be necessary to restart the compressor (see sec. 6.8.10).
6.8.5 Phase Sequence - PH
Triggered in air conditioners with three-phase power supply when the correct phase sequence is not used.
Restore the correct phase sequence, then perform a manual reset (see section 6.8.10) to resolve the alarm.
6.8.6 High Condensation Pressure - HP
Generatedifthecondensationpressure/temperaturesensor,whereconguredandnotinerrorstate,exceedsthevalueA97.Resetswhenthecondensa-
tion pressure/temperature sensor falls below the value A98-A07. Warning only.
Alarm present only in “Advanced” models.
6.8.7 Low Condensation Pressure - LP
Generatediftheexternalcondensationpressure/temperaturesensor,whereconguredandnotinerrorstate,fallsbelowthevalueA98.Resetswhenthe
condensation pressure/temperature sensor exceeds the value A99+A04. Warning only.
Alarm present only in “Advanced” models.
