1. Temperature Parameters
Indoor preset temperature (T
preset
)
Indoor ambient temperature (T
amb.
)
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 first 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;
(2) Dehumidifying Mode
Working conditions and process of dehumidifying
If T
amb
.T
preset
, 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 T
preset
-2 T
amb
.T
preset
, the compressor remains at its original operation state.
If T
amb
.< T
preset
-2 , the compressor will stop, the outdoor fan will stop with a time lag of 30s, and the indoor fan will
operate at low speed.
(1)COOL mode
The condition and process of cooling
If T
amb.
≥T
preset
COOL mode will act, the compressor and outdoor fan will run, and the indoor fan will run at the set
speed.
If T
amb.
≤T
prese
t-2
, the compressor will stop, the outdoor fan will delay 30 seconds to stop, and the indoor fan will run at the set speed.
If Tpreset-2 ≤T
amb
≤T
preset
, the unit will keep running in the previous mode.
In this mode, the reversal valve will not be powered on and the temperature setting range is 16 ~30 .
Protection function
Overcurrent protection
If total current is high, the compressor will run in limited frequency. If total current is too high, the
compressor will stop, the
outdoor fan will delay 30 seconds to stop, indoor unit will display E5 and outdoor
yellow light will blink 5 times.
Antifreezing protection
When the antifreezing protection is detected, the compressor will stop, the outdoor fan will stop after 30 seconds, and the
indoor fan and swing motor will keep running in the original mode. When antifreezing protection is eliminated and the
compressor has stopped for 3 minutes, the compressor will resume running in the original mode.
Protection
Protection is the same as that under the cooling mode.
