Off: Compressor stops.   
Decrease:  Decrease  the  running  frequency  to 
the lower level.   
Hold: Keep the current frequency.   
Resume: No limitation for frequency. 
 
16.4.4 Auto-mode 
This  mode  can  be  chosen  with  remote 
controller  and  the  setting  temperature  can  be 
changed between 17~30℃(63~86°F). 
In auto mode, the machine will choose cooling, 
heating or  fan-only mode according  to ΔT (ΔT 
=T1-Ts). 
-2℃(-3.6°F )  ≤ΔT≤2℃
(3.6°F ) 
Indoor  fan  will  run  at  auto  fan  of  the  relevant 
mode. 
The louver operates same as in relevant mode. 
If the machine switches mode between heating 
and cooling, the compressor will keep stopping 
for  15  minutes  and  then  choose  mode 
according to T1-Ts. 
If  the  setting  temperature  is  modified,  the 
machine will choose running function again. 
For MCD1-24HRFN1-MT0W(GA), 
In  auto  mode,  the  machine  selects  cooling, 
heating or fan-only mode on the basis of T1,Ts 
and T4.

16.4.5 Drying mode 
Drying mode works the same as cooling mode 
in breeze speed. 
All protections are active and the same as that 
in cooling mode. 
For MCD1-24HRFN1-MT0W(GA), 
In drying mode, AC operates the same as auto 
fan in cooling mode. 
All  protections  are  activated  and  operate  the 
same as they do that in cooling mode. 
Low Room Temperature Protection 
If the room temperature is lower than 10°C, the   
compressor  ceases  operations  and  does  not 
resume until room temperature exceeds 12°C. 
16.4.6 Timer function 
16.4.6.1 Timing range is 24 hours. 
16.4.6.2  Timer  on.  The  machine  will  turn  on 
automatically when reaching the setting time. 
16.4.6.3  Timer  off.  The  machine  will  turn  off 
automatically when reaching the setting time. 
16.4.6.4 Timer on/off. The machine will turn on 
automatically  when  reaching  the  setting  “on” 
time,  and  then  turn  off  automatically  when 
reaching the setting “off” time. 
16.4.6.5 Timer off/on. The machine will turn off 
automatically  when  reaching  the  setting  “off” 
time,  and  then  turn  on  automatically  when 
reaching the setting “on” time. 
16.4.6.6 The timer function will not change the 
AC current operation mode. Suppose AC is off 
now,  it  will  not  start  up  firstly  after  setting  the 
“timer  off”  function.  And  when  reaching  the 
setting time, the  timer  LED  will  be  off and  the 
AC running mode has not been changed.
