2) The machine will quit from the rating capacity test mode if running for 5 hours or changing fan speed or
setting temperature.

Turbo function in heating mode. (press the “ TURBO ” button on remote controller)
1) Elevate current frequency (excluding F8) to a higher grade. If indoor fan is in low speed or pause caused
by defrosting or anti-cold-wind function, frequency of compressor will not be elevated one grade until these limit has
been released.
2) Indoor fan changes to turbo speed and anti-cold-wind function is valid.
9.8 Auto mode function
9.8.1 This mode can be chosen with 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 Δ T( Δ T =T1-Ts).

9.8.2 Indoor fan will choose auto speed of relevant mode.
9.8.3 If the machine switches mode between heating and cooling, compressor will keep stopping for 15
minutes and then rechoose mode according to Δ T.
9.8.4 If the setting temperature is modified, the machine will rechoose running function.
9.9 Forced operation function
9.9.1 Forced cooling and auto function can carry out with a touch button. In these two modes, the machine can be
changed by remote controller to any other mode at any moment.
9.9.2 When the machine is off, pressing the touch button once, the unit will enter forced auto mode. When the
machine is off, pressing the touch button twice within 5s, the unit will enter forced cooling mode. When the unit is
running at forced auto or forced cooling mode, pressing the touch button continuously, the unit will be turned off.
9.9.3 In forced operation mode, all general protections is available.
9.9.4 In forced cooling mode, the unit will run with fixed frequency F2 at low speed. 30 minutes later, the unit will turn
to normal auto mode with setting temperature 24
℃
.
9.9.5 In forced auto mode, the unit will run with setting temperature 24

9.10 Action of 4-way valve
In heating, fan-only, standby or turning off mode, 4-way valve is off, while in cooling\drying and forced
