3) In heating operation, the mode changes to [UL] if thermostat
is turned off.
4) If Ta ≥ 25°C when heating operation has started and when
defrost operation has been cleared, the air conditioner
operates with (H) mode or higher mode for
1 minute after Tc entered in E zone of cool air discharge
preventive control (No. 7).
5) In automatic cooling/heating operation, the revolution
frequency of (HH) is set larger than that in the standard
cooling/heating operation.
However the revolution frequency
is restricted in the automatic
heating operation as shown in
the following figure.
6) Self-clean operation
When performing self-clean operation after stopping the
cooling operation, the mode becomes 210 rpm.
1) In heating operation, the indoor fan is controlled based on
the detected temperature of Tc sensor or Tcj sensor. As
shown below, the upper limit of the revolution frequency is
restricted.
However B zone is assumed as C zone for
6 minutes and after when the compressor activated.
In defrost operation, the control value of Tc is shifted by 6°C.
