Heating mode:
Current
frequency(Hz) Current limit
value(A) Frequency limit
HEAT_F16 IHEATLMT12 Decrease the frequency to
HEAT_F4 and run at HEAT_F4 for
3 minutes.
After that, the frequency will be
adjusted according to the capacity
demand and rise to the upper
level every 3 minutes
(When the frequency>Heat_F4 via
capacity demand).
HEAT_F15 IHEATLMT11
HEAT_F14 IHEATLMT10
HEAT_F13 IHEATLMT9
HEAT_F12 IHEATLMT8
HEAT_F11 IHEATLMT7
HEAT_F10 IHEATLMT6
HEAT_F9 IHEATLMT5
HEAT_F8 IHEATLMT4
HEAT_F7 IHEATLMT3
HEAT_F6 IHEATLMT2
HEAT_F5 IHEATLMT1
If the current frequency is lower than HEAT_F4, the frequency will
not be limited.
After 10s of the compressor start, if the current>IHEAT, the AC will
display the failure for 30 seconds and stop. The AC will restart 3
minutes later.
7.3.7 Indoor / outdoor unit communication
protection
If the indoor units cannot receive the feedback
signal from the outdoor unit for 2 minutes, the
system will stop and display the failure.
7.3.8 High condenser coil temp. protection.
When T3>65
℃
for 3 seconds, the compressor
will stop while the indoor fan and outdoor fan will
continue running.
When T3<52
℃
, the protection will reset and the
compressor will restart after 3 minutes.
7.3.9 Outdoor unit anti-freezing protection
When T2B<0 ℃ for 250 seconds, the indoor unit
capacity demand will be set as zero and reset to
normal when T2B>10
℃
.
7.3.10 Oil return
Running rules:
1.If the compressor frequency stays lower than
RET_OIL_FREQ1_ADD for
RET_OIL_TIME1_ADD, the system will rise the
running frequency to RET_OIL_FREQ2_ADD for
RET_OIL_TIME2_ADD and then resume back to
former frequency.
2.During the oil return process, the EXV will stay
at 300p setting while the indoor units will keep the
current running mode.
7.3.11 Compressor preheating functions
----Preheating permitting condition:
If T4 (outdoor ambient temperature) ＜ 3 ℃ when
newly powered on or if T4
＜
3
℃
and compressor
had stopped for over 3 hours, the compressor
heating cable will be activated.
----Preheating mode:
A weak current flows through the windings of the
compressor through its wiring terminal, then the
compressor stays heated while it is off.
----Preheating release condition:
If T4
＞
5
℃
or the capacity demand isn’t zero,
preheating function will stop.
7.3.12 Compressor crankcase heater
----Preheating permitting condition:
①
When T4<3
℃
within 5 seconds of being
plugged in, the crankcase heater will be
active.
②
When T4<3
℃
and the compressor is not
running for 3 hours, the crankcase heater will
be active.
----Preheating release condition:
When T4
≧
5
℃
or the indoor has any capacity
demand, the crankcase heater will stop working.
