Indoor Fan Motor Operation - Panasonic CS-XE9CKE Service Manual

Values of T1, T2, and T3 depend on remote control setting temperature, as shown in below table. After the adjustment of T1, T2
and T3 values, the operation mode for that particular environment and remote control setting is judged and performed, based on
the above operation mode chart, every 30 minutes.
Remote Control Setting Temperature (°C)
There is a temperature shifting on T1, T2, and T3 if the operation mode judged is changed from Cooling/Soft Dry to Heating or vice
verse.
Operation Mode change from
Cooling/Soft Dry → Heating
Heating → Cooling/Soft Dry
Example of operation mode chart adjustment:
From the above table, if remote control setting temperature = 25,
T1 = 25 + 7 = 32; T2 = 25 + 6 = 31; T3 = 25 - 7 = 18
The operation mode chart for this example is as shown in below figure and the operation mode to be performed will depend on
indoor intake air temperature and outdoor air temperature at the time when the judgment is made.
