The machine will choose cooling, heating or fan-only mode according to ΔT (ΔT =T1-Ts).
For MS9A-09CR-QC4(A), MS9A-12CR-QC4(A), MS9A-18CR-QC0 models:
ΔT=T1-Ts Running mode
ΔT>2℃
Cooling
-3≤ΔT≤2℃
Fan-only
ΔT<-3℃
Heating
(for cooling only models, they will run at
fan-only mode)
For other models:
ΔT=T1-Ts Running mode
ΔT>2℃
Cooling
-1≤ΔT≤2℃ Fan-only
ΔT<-1 ℃ Heating
(for cooling only models, they
fan-only mode)
AC will run in auto mode in the below cases:
(1) Press the forced auto button.
(2) If AC is off, it will run in auto mode when timer on function is active.
