6.3 Brief Description of Modes and Functions
1. Temperature Parameters
◆
Indoor preset temperature (Tpreset)
◆
Indoor ambient temperature (Tamb.)
2. Basic Functions
Once energized, in no case should the compressor be restarted within less than 3 minutes. In the situation that memory function
is available, for the rst energization, if the compressor is at stop before de-energization, the compressor will be started without a
3-minute lag; if the compressor is in operation before de-energization, the compressor will be started with a 3-minute lag; and once
started, the compressor will not be stopped within 6 minutes regardless of changes in room temperature;
(1) Cooling Mode
①
Working conditions and process of cooling
Cooling conditions and process(09k)
a. When Tamb.≥Tpreset the unit starts cooling. In this case, the IDU fan motor, ODU fan motor and compressor run, and the IDU fan
motor runs at set speed;
b. When Tamb.=Tpreset-3℃, the compressor continuously operates below the frequency of 15Hz (not including 15Hz) for 15mins. If
Tamb.=Tset-3℃ still keeps the same, the compressor stops operation;
c. When Tamb.≤Tpreset-4℃, the compressor stops operation; ODU fan motor stops operation with a delay of 30s and IDU fan motor
operates at set speed;
d. When Tpreset-2℃＜Tamb.＜Tset, the unit will maintain its previous running status.
Cooling conditions and process(12k)
a.When Tamb.+Tindoor supplementary≥Tpreset, the unit starts cooling. In this case, the IDU fan motor, ODU fan motor and
compressor run, and the IDU fan motor runs at set speed;
b. When Tamb.+Tindoor supplementary≤Tpreset-2℃, the compressor stops operation; ODU fan motor stops operation with a delay
of 30s and IDU fan motor operates at set speed;
c.When Tpreset-2℃＜Tindoor amb.+Tindoor supplementary＜Tpreset, the unit will maintain its previous running status.
Under this mode, the four-way valve will be de-energized and temperature can be set within a range from 16 to 30
o
C.
If the compressor is shut down for some reason, the indoor fan and the swing device will operate at original state.
②
Protection
◆
Antifreeze protection
Under cooling and dehumidifying mode, 6 minutes after the compressor is started:
If T evap≤2
o
C, the compressor will operate at reduced frequency.
If T evap≤-1
o
Cis detected for durative 3 minutes, the compressor will stop, and after 30 seconds, the outdoor fan will stop; and under
cooling mode, the indoor fan and the swing motor will remain at the original state.
If T evap. ≥10
o
Cand the compressor has remained at OFF for at least 3 minutes, the compressor will resume its original operation
state.
◆
Total current up and frequency down protection
If I
total
≤6, frequency rise will be allowed; if I
total
≥7, frequency rise will not be allowed; if I
total
≥8, the compressor will run at reduced
frequency; and if I
total
≥9, the compressor will stop and the outdoor fan will stop with a time lag of 30s.
(2) Dehumidifying Mode
①
Working conditions and process of dehumidifying
If Tamb>Tpreset, the unit will enter cooling and dehumidifying mode, in which case the compressor and the outdoor fan will operate
and the indoor fan will run at low speed.
If Tpreset -2
o
C≤Tamb≤Tpreset, the compressor remains at its original operation state.
If Tamb.< Tpreset -2
o
C, the compressor will stop, the outdoor fan will stop with a time lag of 30s, and the indoor fan will operate at
low speed.
②
Protection
Protection is the same as that under the cooling mode.
