ΔT = TA - TS
Running mode
ΔT ＞ 4F
Cooling
-2F ≤ ΔT ≤ 4F
Fan-only
ΔT < -2F
Heating (Setting temperature is TS-1F)
 The unit will default to running mode when in auto mode under the following circumstances:
 Powering on, changing mode to auto mode or adjusting temperature in auto mode will cause the
unit to default to running mode again.
 A: In auto mode, if the compressor does not run for 15 minutes check condition B.
 B: If ΔT<-8℉ or ΔT ＞2℉, the unit will default to running mode again according to ΔT until the
compressor stops.
