SET DATA
1) Based on the difference between TA and TS, the
operation frequency is instructed to the outdoor unit.
2) Cooling operation
Every 90 seconds, GA calculates TA-TS, the fluctuation,
and the correction amount of compressor frequency
TA
(n) –
TS
(n)
: Room temp. difference
n
: Detecting counts
(n) : Room temp.fluctuation
TA
(n-1)
– TS
: Detecting counts of 90 seconds before
n – 1
3) Heating operation
Every 1 minute (60 sec.), GA calculates TA-TS, the
fluctuation, and the correction amount of compressor
frequency.
TS
(n) –
TA
(n)
: Room temp. difference
n
: Detecting counts
(n – 1): Room temp.fluctuation

TA
n – 1
: Detecting counts of 1 minute before
4) Dry operation
The frequency correction control is same as those of the
cooling operation.
However the maximum frequency is limited to approxi-
mately "S6".
Note) When LOW is set up, the maximum frequency is
limited to approximately "SB".
1) The judgment of selecting Cooling/Heating mode is
carried out as shown belows
When TA exceeds Tsh+1.5°C after 10 minutes at
thermostat off, the operation mode
TA ˚C
Cooling
+1.5
TSC or TSH
–1.5
When
TA is lower Tsc-1.5°C after 10 minutes at thermostat off, the operation mode
changes COOL to HEAT mode.
2) For the automatic capacity control after judgment of cooling/heating, see Item 4.
3) For temperature correction of room temp. control at automatic heating, see Item 3.
