For 12k models(Excluding MDCA3-12HRDN1, MDTB1-12HWDN1,MDFA-12HRFN1):
Electrical Control Function
198 Electrical Control System
For other models:
∆ T=T1-Ts Running mode
∆ T
≥
2
℃
Cooling
-1 ≤∆ T<2
℃
Fan-only
∆ T<-1
℃
Heating
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.
1.3.5 Drying mode
1.3.5.1 Indoor fan speed is fixed in low(for console, it is fixed in breeze) and can’t be changed. The louver
angle is the same as in cooling mode.
1.3.5.2 Low indoor room temperature protection
In drying mode, if room temperature is lower than 10
℃
, the compressor will stop and not resume until room
temperature exceeds 12 ℃ .
1.3.5.3 Evaporator anti-freezing protection, condenser high temperature protection and outdoor unit
frequency limit are active and the same as that in cooling mode.
For other models:
Drying mode works the same as cooling mode in low speed.
All protections are active and the same as that in cooling mode.
1.3.6 Timer function
1.3.6.1 Timing range is 24 hours.
1.3.6.2 Timer on. The machine will turn on automatically when reaching the setting time.
1.3.6.3 Timer off. The machine will turn off automatically when reaching the setting time.
1.3.6.4 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.
1.3.6.5 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.
1.3.6.6 Only for MCA2-12HRDN1-Q:
The timer function will change the AC current operation mode. Suppose users set the “timer off” function and
AC is off now, the AC will turn on firstly and then turn off when reaching the setting time.
For other models:
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.
1.3.6.7 The setting time is relative time.
