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 filter maintenance warning (HFI) is displayed whenever the number of hours of operation set in parameter A91 (PAr menu, PA alarms) is reached,
which defines the filter maintenance interval.
The filter is an optional component; if the filter is not installed, when the filter 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
define 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 filter before the maintenance warning is displayed).
The filter maintenance warning can be reset by resetting the filter 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 off.
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 off.
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 configured 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 configured 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.
