Operation starts in advance so that the room temperature reaches the preset value at
the set time.
●
The operation time is obtained as follows depending on the room temperature when
operation starts.
(1) Calculation method of the moved-up time.
Moved-up time (MT) = Moved-up time depending on the temperature difference (OT) +
compensation time (HT).
MT is at least 1 minute if OT is not zero.
Cooling
(MT) 00 ~ 60 min.
(OT) 00 ~ 60 min.
(HT) –60 ~ 60 min.
Obtain OT (moved-up time depending on the temperature difference) from the table below.

The preset temperature value shown above does not include any shift value.
(2) Compensation
1 The “Attained” state is monitored and a “Not attained” check is done to revise the
compensation time (HT).
“Attained” monitor
Continuously monitored during “NICE TEMPERATURE” operation.
(Cooling)
When the room temperature < Set value + compensation shift, it’s operated same
as above.
“Not attained” check
Performed once when the “NICE TEMPERATURE” timer is completed.
(Cooling)
When the room temperature > Set value + compensation shift +1°C, it’s operated
same as above.
❈
If the room temperature is 1°C from the set value + compensation shift,
compensation is not done.
