Supplementary information
1) Energy-saving warm airflow control
Start timing: Starts when thermo is switched from ON to OFF after HEAT mode and the hot adjust process
have finished.
End timing: Ends when any of the following conditions is met:
(1) The unit is switched to any mode other than HEAT.
(2) The unit enters DEFROST operation.
(3) Intake temperature ! Set temperature
(4) More than 5 minutes after the start of energy-saving warm airflow fan control
(5) The unit is switched to hot adjust.
•Energy-saving warm airflow control keeps the vane in the downward position and maintains the fan speed
when thermo is turned OFF.
2) Thermo differential setting
Overview: Enables the thermo differential feature to be switched by remote controller function selection during
COOL operation. Settings are normal (1 degree), 5 degrees or 10 degrees.
Purpose: When the unit is installed to air-condition equipment items or for similar applications where the COOL
operation is used year-round, the compressor is frequently switched ON and OFF in winter when the
air conditioning load is low. This frequent switching can shorten the compressor service life.
The thermo differential feature is used to reduce the number of times the compressor is switched ON
and OFF, to prevent its service life from being shortened.
Changes: "COOL thermo differential switching" has been added to function selection (mode: 19).
Applicable mode: COOL THERMO only. HEAT THERMO settings can't be changed.
Other: Setting at time of factory shipment is "NORMAL THERMO" (mode: 01).
