d3 Power Supply ON/OFF 2 (Restarting Function After Power Failure)
This function is used to start the unit operation again automatically when the power supply is recovered after the power
failure over 2 seconds.
The standard unit is started operation again automatically with all the same operating conditions such as operation mode,
etc. in case of the power failure within 2 seconds.(The compressor is started operation again after three minutes guard in
addition to 2 seconds power failure as a maximum.)
When this function is used in the condition that there is no person to operate the unit, provide the system with monitoring
for disaster prevention
NOTE
• In case of the power failure during the unit stoppage, the unit remains stopped after recovering the power supply. When the compres-
sor does not reach xed temperature, the system may not restart automatically after turning on the power supply by hot-start control.
•
*Hot-start Control:
The control program that cannot operate if xed temperature is not being supplied after the power is turned ON.
d4 Prevention for Cooling Discharge Air Temperature Decrease
This function is used to change Thermo-ON/OFF conditions at cooling operation and prevent discharge air temperature
decrease. In the result, the perception of cold draft is eliminated.
Thermo-OFF Conditions:
a. Cooling Operation (including Dry Operation) and
b. Indoor air discharge temp. <11 ºC has been kept for 3 minutes.(Thermo-OFF when discharge air temperature is
low.)
Thermo-ON Conditions:
a. Indoor discharge air temp. >13 ºC and
b. Thermo-ON depends on indoor discharge air temperature.(Not Thermo-ON when discharge air temperature is
low.)
d5 Prevention for Heating Discharge Air Temp. Decrease
This function is used to prevent discharge air temperature decrease by lowering actual fan speed than the indications on
the remote control switch.
Indications on Remote Control Switch Actual Fan Speed

MEDIUM LOW
LOW LOW
d6 Room Temperature Control for Energy Saving
When outdoor temperature air thermistor is detecting that the air-conditioning load is low from the outdoor temperature.
This function is used to automatically save energy.
d7 Not Prepared
E1 Ventilation Mode (KPI) / All fresh mode (Econofresh)
Ventilation Mode (KPI)
This function is used to set the ventilation mode of the total heat exchanger. The setting condition and the ventilation
mode are as shown below.

00 Automatic Ventilation
Selecting effective ventilation mode (Total Heat Exchanging Ventilation or Bypass
Ventilation) for energy saving by detecting the temperature difference between the outdoor
temperature and the room temperature.
01
Total Heat Exchanging
Ventilation
The heat exchanging is performed continuously when the total heat exchanger is oper-
ated.
02 Bypass Ventilation
The heat exchanging is not performed continuously when the total heat exchanger is
operated.
