3. 3 Operation Modes and Functions 3.3.1 Auto mode function requirement TS range is 62 ℉ ℉ ℃ ℃). When T1<TS-1, select the setting temperature of TS-1 for Heating operation’s temperature. When TS+2≥T1≥TS-1,select the Fan-only mode. When T1>TS+2, select the setting temperature(TS ) for Cooling operation’s temperature. - Page 9 When the unit is off, the compressor stops at first, and the indoor/outdoor fan will stop for a delay of 5seconds. (If it operates at heating mode, the outdoor fan will be off for a delay of 30 seconds). The ION/TIMER functions are valid at the cooling mode. 3.3.4 Drying mode function requirement At Drying mode, TS can’t be controlled by display panel, and LED display as T1.
- Page 10 The ION/TIMER functions are valid at the heating mode. 3.4.6 Heating mode function requirement(for Heat Pump) TS range is 62 ( 17 ℉ ℉ ℃ ℃). T1≤TS+41 , compressor operates; ℉( ℃) T1﹥TS+42.8 , compressor stops; ℉( ℃) T1﹤41 ℉( ℃), heat pump mode is invalid;...
- Page 11 It’s invalid for compressor’s delay operation protection when unit is at defrosting function mode. On defrosting process, if malfunction occur, or power off, or change for non-heating mode, unit will esc defrosting function mode. At Heat pump mode, if P1 occurs, compressor, indoor/outdoor fan stop immidiately.
