•
T°room ≤ (T°set+T°camb) -3°C MAXIMUM frequency;
•
(T°set+T°camb) -3°C < T°room ≤ (T°set+T°camb) -1°C MODULATED frequency;
•
(T°set+T°camb) -1°C < T°room. ≤ (T°set+T°camb) +1°C MINIMUM frequency;
•
T°room. > (T°set+T°camb) +1°C compressor OFF;
The frequency is recalculated and modified as necessary at intervals of 3 minutes. The speed of the internal fan
works, if not specifically set, in accord the temperature of the internal heat-exchanger, in particular:
•
T°int. heat-exchanger < 31°C IDU fan and air-sweep stop to prevent cold air ;
•
31°C ≤ T°int. heat-exchanger ≤ 38°C IDU fan starts working SUPER-LOW speed ;
•
T°int. heat-exchanger > 38°C IDU fan and air-sweep operate in according with Remote Control ;
4.3.1. Defrost:
DEFROST is enabled after 20 minutes of the compressor start to the occurrence of any of these conditions:
•
T°out - T°ext. heat-exchanger > 7°C and T°out > 5°C (for next 5 minutes);
•
T°out - T°ext. heat-exchanger > 15°C and -1°C < T°out ≤ 5°C (for next 2 minutes);
•
T°out - T°ext. heat-exchanger > 8°C and -8°C < T°out ≤ -1°C (for next 2 minutes);
•
T°out - T°ext. heat-exchanger > 7°C and T°out ≤ 8°C (for next 5 minutes);
•
T°est. exchanger ≤ -8°C and defrost function isn’t activated in the previous 120 minutes;
The compressor reduces the frequency to 38 Hz and then work at least for 28 sec. after which the outdoor fan is
turned off. After another 2 sec. also 4-ways valve is disabled, so the compressor increases the frequency to the
limit of 60 Hz. The defrost ends when the T°ext. heat-exchanger ≥ 12 ° C or 10 minutes after it.
In particular the end of the defrosting expects to decrease the frequency to 38 Hz followed by a stage at a constant
frequency of 28 sec. Finally 2 sec. to enable 4-way valve and further 5 sec. before that frequency starts to
increase.
4.4 Dehumidify only mode :
When used in this mode, the air conditioner only eliminates the humidity in the room. In this mode, both T°room
and fan speed settings are ignored, which correspond to minimum.
After setting the desired temperature, T°room is constantly monitored by software and it is compared with T°set.
Depending on the difference between these two temperature, compressor is turned ON/OFF in according to values
described
below
:
•
T°room - T°set <-2°C compressor OFF;
•
T°room – T°set > 1°C compressor ON;
The compressor (ON) switches one stage to the max frequency for 6 min. and one at a minimum for 10 min.
4.5 Fan mode:
In this mode the air conditioner does not perform any action with regard to temperature and air humidity in the
room. At this stage you can select the fan speed and air sweep.
All other outputs are switched off and only DIRTY
FILTER alarm ( FS ) is enabled.
