Auto Mode
This mode can be chosen with remote controller and the setting temperature can be
changed between 61°F~86°F(16°C~30
).
In auto mode, the machi ne will choos e cooling, heatin g or fan-only mode according to
ΔT (ΔT =T1 -Ts).

Indoor fan will run at auto fan of the relevant mode. The louver operates same as in
relevant mode.
If the compressor keep stopping for 10 minutes or the setting
temperature is modified, the machine will choose mode according to ΔT again.
Evaporator low -temperature Protection
Condition:
Cooling:
Indoor coil temperature (T2) is lower than TE5 (logical calculation between 28F-35F) for 2 minutes,
Outdoor fan and compressor will turn o. When Indoor coil temperature (T2) is higher than TE6
(logical calculation between 50F-55F) the compressor and outdoor fan will restart.
