7.4.5 Prevent Over-Heating
For console: In heating mode, when the indoor unit has no capacity requirement due to indoor room
temperature increased, the Indoor fan will run in breeze. (Anti-cold wind function has the priority)
For ceiling& floor: In heating mode, when the indoor unit has no capacity requirement due to indoor room
temperature increased, the Indoor fan will run in low. (Anti-cold wind function has the priority)
For new four-way cassette (compact)&A5 duct: In heating mode, when the indoor unit has no capacity
requirement due to indoor room temperature increased, if outdoor fan and compressor stop, the Indoor fan
will run in setting fan speed, otherwise, the Indoor fan will run in low. (Anti-cold wind function has the priority)
7.4.6 Defrosting
Defrosting operation (Available for heating only).
Defrosting Actions:
a. Indoor fan switches off, anti-cold wind function is valid.
b. After defrosting ends, indoor fan runs according to anti-cold wind function in heating mode.
7.4.7 Auto-mode
This mode can be chosen by remote controller and the setting temperature can be changed between
17~30
℃
.
In auto mode, the machine will choose cooling, heating or fan-only mode according to the difference
between T1 and TS.
