14.2. PROGRESSIVE START-UP
The Aqu@ Scop HT 18-9 is equipped with a progressive starter
(soft start) for the C1 compressor. The starter is situated in the
electrical box of the outdoor unit and marked " AS1 ".
It is important to check the following settings:
²
Start slope 1s
²
Stop slope 0s
²
Minimum starting voltage 60%

IMPORTANT :
The compressors are equipped with a soft starter. The starter is situated in the electrical box of the outdoor
unit and marked " AS1/2 ".
230V +/-10% 50Hz
THE LED’s INDICATE THE FOLLOWING CONDITIONS:
Green

Red diode Meaning Recommended action Comments
On Off No fault
Off Off
No supply voltage present
at starter terminals.
Check the power supply to the PAC.
Check the condition of the 230V
protection fuse. Replace the fuse if it
has melted.
Flashing Off
Insufficient supply voltage
(compressor stopped).
Measure the compressor starter
supply voltage at rest. Cut the power
supply to the PAC and check whether
or not the fault reappears. Refer to
the following cause in the event of
repeated failure.
Defective starter power
supply component.
Cut the power supply to the PAC. If the
fault persists, replace the starter.
On
Flashing
twice Insufficient compressor
starting voltage (<190V).
Check the mains supply voltage at
rest. Contact the electricity supplier if
< 207V.
The alarm resets itself automatically
after 5 min. If the fault re-occurs
during the next start-up procedure,
the compressor seizes and the power
supply has to be disconnected to reset
it.
With the compressor running, check
the mains supply voltage and the
starter output voltage. In the event of
major voltage drop, check the diameter
of the PAC power supply cable. As
a last resort, contact the electricity
supplier.
On
Flashing 3
times Excessive compressor
starting current.
Force the compressor to start several
times and check whether it is a one-
off or recurring fault.
The alarm resets itself automatically
after 5 min. If the fault re-occurs
during the next start-up procedure,
the compressor seizes and the power
supply has to be disconnected to reset
it.
If the fault persists, when the
compressor is running, check for
normal current draw. In the event of
excessively-high current draw, replace
the compressor.
Starter fault. Replace the starter.

sequence
Force the compressor to start several
times and check whether it is a one-
off or recurring fault.
The alarm resets itself automatically
after 5 min. If the fault re-occurs
during the next start-up procedure,
the compressor seizes and the power
supply has to be disconnected to reset
it.
In the event of a persistent fault, check
the compressor power supply cable.
