off and restart 30s later, if protection happened
3  times  when  fan  motor  restarts  continuously,
the  unit  will  stop  and  the  LED  will  display  the
failure.
When outdoor fan speed keeps too low (lower
than  100RPM)  or  too  high  (higher  than
1500RPM)  for  60s,  the  unit  will  stop  and  the
LED  will  display  the  failure.  Malfunction  is
cleared 30s later.

For A6 Duct& HESP Duct:
If a fault occurs on the air volume regulator or
the regulator enters protection mode, it sends
the error message CF and an instruction to
reduce fan speed to the master. The message
and the instruction can be inquired with the
remote controller or the wired controller. (Fault
and protection information are displayed for
one minute). After a fault occurs, the master
unit shows the error code E3 and the fault count
for one minute. If the fault occurs three times,
then the fan is unable to resolve the problem
independently. External shutdown by a remote
controller, wired controller, or central controller
must be used to clear the fan fault and fault
count. The fan runs normally for 5 minutes
while clearing fault count.

No malfunction

1:P0 Overcurrent
2:Overpressure

8:Communication fault
9:Parameter fault
10:L3 Current limited

12:Target speed cannot be met during the
static pressure calculation process.

15.3.5 Inverter module protection

The Inverter module has a protection function
about current, voltage and temperature. If these
protections happen, the corresponding code
will display on indoor unit and the unit will stop
working.

15.3.6 Indoor fan delayed open function

When the unit starts up, the louver will be active
immediately and the indoor fan will open 7s
later.
If the unit runs in heating mode, the indoor fan
will be also controlled by anti-cold wind
function.

15.3.7 Compressor preheating functions

Preheating permitting condition:
If T4

＜

℃

(37.4°F) and the machine connects

to power supply newly within 5 seconds or if T4

＜

℃

(37.4°F) and compressor has stopped for

over 3 hours, the compressor heating cable will
work.
Preheating mode:
A  weak  current  flow  through  the  coil  of
compressor  from  the  wiring  terminal  of  the
compressor,  then  the  compressor  is  heated
without operation.
Preheating release condition:
If  T4≥5

℃

(41°F) or the compressor starts

running, the preheating function will stop.

15.3.9 Condenser high temperature T3

protection

---55°C(131°F)<T3<60°C(140°F),

the

compressor  frequency  will  decrease  to  the
lower  level  until  to  F1  and  then  runs  at  F1.If
T3<54°C(129.2°F),  the  compressor  will  keep
running at the current frequency.
---T3<52°C(125.6°F),  the  compressor  will  not
limit  the  frequency  and  resume  to  the  former
frequency.
---T3>60°C(140°F)  for  5  seconds,  the
compressor will stop until T3<52°C(125.6°F).

15.3.10 Evaporator low temperature T2
protection

---T2<0°C(32°F), the compressor will stop and
restart when T2

≧

5°C(41°F).

---0°C(32°F)

≦

T2<4°C(39.2°F), the compressor

frequency will be limited and decreased to the
lower level
