- Off timer can be set using remote control the unit with timer set will stop operate at set time 37
- Off timer control 37
- On timer can be set using remote control the unit with timer set will start operate earlier than the setting time this is to provide a comfortable environment when reaching the set on time 60 minutes before the set time indoor at fan speed of lo and outdoor fan motor start operate for 30 seconds to determine the indoor intake air temperature and outdoor air temperature in order to judge the operation starting time from the judgment the decided operation will start operate earlier than the set time as shown below 37
- On timer control 37
- Timer control 37
- When the power supply is cut off during the operation of air conditioner the compressor will re operate within three to four minutes there are 10 patterns between 2 minutes 58 seconds and 3 minutes 52 seconds to be selected randomly after power supply resumes 2 this type of control is not applicable during on off timer setting 37
