If “cooling” is selected during “sensor dehumidification” operation the operation continues as it is with the thermo ON. The 3 minutes delay is not started. The set temperature and fan speed depend on the remote control signal. It is same for “cooling” – – – – “sensor dehumidification”. It is same for “AUTO” sensor dehumidification cooling “sensor dehumidification” “cooling”.

The filter sign lights after 100 hours operation of the room fan. The lamp goes out when the POWER SWITCH set to OFF and ON again.

After the failure mode is started (indicator lamp flickering), rapid mode changing cannot be done.

.
If the operation is made by the nice temperature reservation during the sleep operation, the normal operation continuously occurs, and for the advance time, the temperature difference between the set temperature without sleep shift and “room temperature” is used.

●
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.

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.
(Heating) When the room temperature < Set value + compensation shift, it is regarded to be “attained” and 5 minutes are reduced from the compensation time. (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.
(Heating) When the room temperature < Set value + compensation shift 1
°
C,
it is regarded to be “Not attained” and 5 minutes are added to the compensation time. (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.
