Page 35
ELECTRONIC FUNCTION 9.4.2.4 Low evaporator coil temperature T2 protection When the evaporator coil temp.T2 keeps lower than TE5 for 5 minutes, the compressor and outdoor fan will shut off. When T2 is higher than TE6, the compressor and outdoor fan will restart 9.4.2.5 High condenser temperature T3 protection(only for AWSI-HMF024-N11) When T3≥TE10, the compressor will stop and restart until T3<TE11.
Page 36
ELECTRONIC FUNCTION 9.4.3 Heating Mode 9.4.3.1 Compressor running rules: Once the compressor starts up, it will run 7 minutes. And then it will follow the below rules: When indoor room temp.T1 is higher than Tj, the compressor and outdoor fan will shut off. When T1 is lower than Tk, the compressor and outdoor fan will start up.
Page 37
ELECTRONIC FUNCTION For AWSI-HMF024-N11: When the compressor is on, the indoor fan can be set to high/med/low/auto. And the anti-cold wind function has the priority. If the compressor stops caused by the room temperature rising and T2≥TE1-6, the indoor fan will be forced to run at breeze for 127 seconds, if T2<TE1-6, the indoor fan will stop immediately.
Page 38
ELECTRONIC FUNCTION Auto fan action: When T1-Ts>2℃, the indoor fan will run at low speed. When T1-Ts≤0℃, the indoor fan will run at medium speed. 9.4.3.4 Defrosting mode: Defrosting action: For AWSI-HMF024-N11: Condition of defrosting: AC will enter defrosting mode if any of the following items is satisfied. (1) If T3<TC1 and the compressor keeps running over 45 minutes.
Page 39
ELECTRONIC FUNCTION Defrosting action: For other models: Condition of defrosting: 1,AC will enter defrosting mode if all of the following items is satisfied. 1.1 After the compressor keeps running 8 minutes, ΔT ΔT ≥4℃(ΔT=T2-T1) max- 1.2 AC meets A1 or A2. A1: The cumulative compressor running time is between 45~120 minutes.
