Functional specifications
Temperatures and basic functions
To describe the functions there are two temperatures applied.
The preset indoor temperature (T
preset
) and the ambient temperature (T
amb.
).
After energizing the system, the compressor must not be restarted, after a
standstill of at least three minutes. After a blackout, the compressor likewise can
only be restarted after a time gap of at least three (3) minutes, provided that the
system already was switched on (ON status).
If the unit is at on status before
power failure, the compressor shall be restarted with three minutes delay.
After having started the compressor, it runs for further six minutes even if the
ambient temperature changes.
Cooling Mode
Conditions and process
The system starts cooling, if the ambient temperature is higher or equal to the
preset tempe1°C (T
amb
≥ T
preset
+1°C). Under this condition the compres-
sor and the outdoor unit fan are running adequately to the requested perform-
ance. The indoor fan runs at the adjusted speed.
In case of lower or equal ambient temperature in comparison to the preset value
-1°C (T
amb
≤ T
preset
-1°C), the compressor and the outdoor unit fan wil l be
switched off. The indoor fan runs at the adjusted speed.
In the range of ambient temperature being higher than the preset value for -1°C
but lower than the preselection of + 1°C (T
preset
-1°C < T
amb
< T
preset
+1°C) the
system will not change its status.
As to that please compare the following schedule:
In this mode the temperature ranges between 16 to 30°C. On the display of the
indoor unit the symbols “OPERATION, COOLING” and the temperature preset
value are indicated.
After switching
on the unit, the
compressor
starts with three
minutes time
delay!
