• If any one of the following conditions is satisfied,
defrosting ends and the machine switches to normal
heating mode:
• T3 rises above TCDE1.
• T3 maintained above TCDE2 for 80 seconds.
• Unit runs for 10 minutes consecutively in defrosting
mode.

Evaporator Temperature Protection
When the evaporator temperature exceeds a preset
protection value, the compressor ceases operation.

Auto-mode
• This mode can be selected with the remote controller
and the setting temperature can be changed between
17°C~30°C (62 °F~86 °F).
• In auto mode, the machine selects cooling, heating, or
fan-only mode on the basis of ΔT ( ΔT =T1-TS).

no higher than 30°C (86 °F)) every hour. After 2
hours, the temperature stops rising and the indoor
fan is fixed at low speed.
• When heating, the temperature decreases 1°C(2 °F)
(to not lower than 17°C(62.6°F)) every hour. After
2 hours, the temperature stops decreasing and the
