8.3 Main Protection
8.3.1 Three minutes delay at restart for
compressor
1 minute delay for the 1
st
time start-up and 3
minute delay for subsequent starts.
8.3.2 Temperature protection of compressor
top surface.
The unit will stop working when the compressor
top temp. protector activates, and will restart
after the compressor top temp. protector resets.
8.3.3 Temperature protection of compressor
discharge pipe
When the compressor discharge temp. is
getting higher, the running frequency will be
limited as per the below rules:
---Compressor discharge temp. T5>115
℃ for
5s, compressor stops.
---108<T5<115
℃ , decrease the frequency to
one lower level every 3 minutes.
---90<T5<105
℃ , keep running at the current
frequency.
----T5<90
℃ , no limit for frequency.
8.3.4 Fan speed is out of control
When Indoor Fan Speed is measured too low
(<300 RPM) for certain time, the unit will stop
and the LED will display the failure.
8.3.5 Inverter module protection
The Inverter module has a protection function
based on current, voltage and temperature. If
these protections activate, the corresponding
code will display on the indoor unit and the unit
will stop working.
8.3.6 Indoor fan delayed start function
When the unit starts up, the louver will be
activated immediately and the indoor fan will
start 10s later.
If the unit runs in heating mode, the indoor fan
will be also controlled by anti-cold draft (Warm
Start) function. Indoor fan will start operating
only after the indoor coil's surface temperature
becomes hot enough. During this delay period,
the defrost light will be illuminated
8.3.7 Compressor preheating functions
Preheating permitting condition:
If T4 (outdoor ambient temperature)
＜
3
℃
and
the machine is connected to the power supply
recently or if T4
＜
3
℃
and compressor has
stopped for over 3 hours, the compressor
heating circuit will activate.
Preheating mode:
A weak current flow through the coil of
compressor through the wiring terminal of the
compressor, then the compressor is kept warm
without operating.
Preheating release condition:
If T4
＞
5
℃
or the compressor starts running,
the preheating function will stop.
8.3.8 Zero crossing detection error
protection
If IC detects that time interval is not correct
continuously for 240s, the unit will stop and the
LED will display the failure. The correct zero
crossing signal time interval should be between
6-13ms.
8.3.9 Condenser temperature protection
---55
℃
<T3<60
℃
, the compressor frequency
will decrease to the lower level until to F1 and
then runs at F1. If T3<54
℃
, the compressor will
keep running at the current frequency.
---T3<52
℃
, the compressor will not limit the
frequency and resume to the former frequency.
---T3>60
℃
for 5 seconds, the compressor will
stop until T3<52
℃
.
8.3.10 Evaporator temperature protection
---T2<0
℃
, the compressor will stop and restart
when T2
>=
5
℃
.
---0
℃≦
T2<4
℃
, the compressor frequency will
be limited and decreased to the lower level
---4
℃
≤T2≤7
℃
, the compressor will keep the
current frequency.
---T2>7
℃
, the compressor frequency will not be
limited.
