Notes:
(1) The indoor fan is operated in the ÒLoÒ mode, OFF for 5 minutes and ON for 1 minute, repeatedly according to the humidity judgement when
the thermostat is turned OFF.
(2) The commpressor is operated forcedly for 3 minutes after operation is started.
(3) The minimum ON time and OFF time of the compressor are 3 minutes.
(4) At the start of operation, the thermostat will be off when room temperature

temperature Ð0.66¡ .
(5) The following procedure is performed to prevent excessive cooling during operation other than start. However, this procedure applies only when the
thermostat is intermittent:
Whether THERMO ON is to continue or not depends on the thermal condition when the 3-minute forced operation ceases.
･
ÒTHERMO ON continuesÓ when room temperature setting temperature +1¡ : (The THERMO operation value is usually the same as that at Òstart of
① ≧
operationÓ)
ÒForced THERMO OFFÓ when room temperature < setting temperature +1¡ : (The same THERMO operation value as that at Òstart of operationÓ is
②
usually used for recovery)
Therefore, if the air-conditioner is stabilized under this thermal condition, it will enter intermittent operation, which is Ò3-minute operation/3-minute stopÓ.
(6) ompressor speed is determined by instruction sent from indoor unit and corrected by outdoor unit according to such factors as capacity, fan speed,
number of units being operated, outdoor temperature, etc.

(4) If the set time is changed during sleep operation, all data including set temperature, time, etc. is cleared and
restarted.
(5) If sleep operation is canceled by the cancel key or sleep key, all data is cleared.
