(2) When
−2°, (−3.6°0) < − =
789:: .
−
;:87:8
> < 1°, (1.8°0)
, the unit will keep its previous
operation status.
(3) When
− =
789:: .
−
;:87:8
> ≤ −2°, (−3.6°0)
,
compressor will stop operation and in 30s later, the outdoor
fan will stop operation;
(4) When the unit is turned off at heating mode, or changes to
another mode from heating mode, the 4-way valve will be de-
energized in 2 minutes later after compressor stops operation
(the compressor is operating during heating mode).
(5) When
:?9:: .
> 30°, (86°0)
, compressor will stop
operation immediately and outdoor fan will stop operation in
30s later.
(6) When the compressor is operating, or changing to heating
from cooling, the 4-way valve will be energized in 2-3 minutes
later.
Condition and process of defrost
(1) When
:?9:: .
≤ 5°, (41°0)
and compressor has
operated for a cumulated time of 3 hours, if
:?9:: 7
<
0°, (32°0),
the unit will enter defrosting mode.
Note: the time will be cleared when
CDEFCCG HIJ. >
5°, (41°0),
compressor has been started up after changing to cooling
mode and defrosting has finished. The time will not be cleared when the
unit stops when reaching temperature point, or for protection, changing
to fan mode, etc).
(2) When heating has operated for continuous 45 minutes, or for
an accumulated 90 minutes, the unit will enter defrosting mode
in 3 minutes after meeting any condition below;
a.
:?9:: 78
> 5°, (41°0),
:?9:: ?
≤
−2°, (28.4°0)
;
b.
−2°, (28.4°0) ≤
:?9:: 78
≤ 5°, (41°0)
,
:?9:: ?
≤ −6°, (21.2°0);
c.
−5°, (23°0) ≤
:?9:: 78
< −2°, (28.4°0),
:?9:: ?
≤ −8°, (17.6°0)
;
d.
−10°, (14°0) ≤ CDEFCCG HIJ. < −5°, (23°0
),
CDEFCCG MNMO − PCIMOQRHENCQ ≤
(CDEFCCG HIJ. 3°, (37.4°0)
e.
CDEFCCG HIJ. < −10°, (14°0)
,
CDEFCCG MNMO – PCIMOQRHENCQ ≤
(CDEFCCG HIJ. −3°, (37.4°0))
After energization, for the first defrosting,
= 0°, (32°0)
; if it is not the
first time of defrosting,
PCIMOQRHENCQ
will be determined by
CDEFCCG MNMO
when quitting defrosting last time; if
CDEFCCG MNMO >
2°, (35.6°0)
,
PCIMOQRHENCQ = 0°, (0°0)
; if
CDEFCCG MNMO ≤
2°, (35.6°0), PCIMOQRHENCQ = 3°, (5.4°0)
.
(3) During defrosting, if operation time for compressor does not
reach 3min, the defrosting will not be entered in the
subsequent 2 hours. At that time, compressor stops operation
and in 30s later, the outdoor fan will stop operation; in another
30s, 4-way valve will stop operation; in 30s later, compressor
will increase its frequency for defrosting. When defrosting lasts
for 450s, or
CDEFCCG MNMO ≥ 10°, (50°0)
, compressor will
decrease its frequency. In 30s later, compressor will stop
operation; in another 30s, 4-way valve will be started up. In
60s later, compressor and outdoor fan will operate. Frequency
for defrosting is 85Hz.
Protections : Total current up and frequency down
When total current
TECEHU ≤ 6V
, increase frequency is allowed; when
total current
TECEHU ≥ 7V
, increasing frequency is prohibited; when total
current
TECEHU ≥ 8V
, the unit operates by decreasing frequency. When
total current
TECEHU ≥ 9V,
the compressor stops operation, and indoor
fan will stop operation after 30s.
3. Common Protection Functions and Fault display under
COOL and HEAT Modes
Overload protection
EDJO
: measured temperature of outdoor heat exchanger under cooling
mode; and measured temperature of indoor heat exchanger under
heating mode.
(1) Cooling overload
a. If
EDJOR ≤ 52°, (125.6°0),
the unit will return to its
original state.
b. If
EDJOR ≥ 55°, (131°0)
, frequency rise is not
allowed.
c. If
EDJOR ≥ 58°, (136.4°0
), the compressor will run
at reduced frequency.
d. If
EDJO ≥ 62°, (143.6°0)
, the compressor will
stop.
(2) Heating overload
a. If
EDJOR ≤ 50°, (122°0),
the unit will return to n its
original operation sate.
b. If
EDJOR ≥ 53°, (127.4°0)
, frequency rise is not
allowed.
c. If
EDJOR ≥ 56°, (132.8°0)
, the compressor will run
at reduced frequency.
d. If
EDJOR ≥ 60°, (140°0)
, the compressor will stop
and the indoor fan will blow residual heat and then
stop.
Exhaust temperature protection of compressor
(1) If exhaust temperature
≥
98°C (208.4°F), frequency is not
allowed to rise.
(2) If exhaust temperature
≥
103°C (217.4°F), the compressor will
run at reduced frequency.
(3) If exhaust temperature
≥
110°C (230°F), the compressor will
stop.
(4) If exhaust temperature
≤
90°C (194°F) and the compressor has
stayed at stop for at least 3 minutes, the compressor will
resume its operation.
Communication fault
If the unit fails to receive correct signals for durative 3 minutes,
communication fault can be justified and the whole system will stop.
Module protection
Under module protection mode, the compressor will stop. When the
compressor remains at stop for at least 3 minutes, the compressor will
resume its operation. If module protection occurs six times in succession,
the compressor will not be started again.
Overload protection
If temperature sensed by the overload sensor is over 115°C (239°F), the
compressor will stop and the outdoor fan will stop with a time lag of 30
seconds. If temperature is below 95°C (203°F), the overload protection
will be relieved.
DC bus voltage protection
If voltage on the DC bus is below 150V or over 420V, the compressor
will stop and the outdoor fan will stop with a time lag of 30 seconds. When
voltage on the DC bus returns to its normal value and the compressor
has stayed at stop for at least 3 minutes, the compressor will resume its
operation.
5.3.1.3 Control of outdoor electric Heating Band
If not in heating mode or temp sensor has malfunction, electric heating
bands of compressor and of condenser will stop operation, otherwise,
the below control logic will be followed.
1. Control of Compressor electric heating Band
a. Conditions for startup: the compressor is off and
meanwhile outdoor ambient temp
≤
-5°C (23°F);
