11.5. Operation Control
11.5.1. Thermostat Control
• Depending on differences between room temperature and setting temperature, compressor operation is decided and starts
operation.
• If temperature difference matches values shown below, thermostat switches off.
11.5.2. Indoor Fan Control
• Manual Fan Speed
Operation starts at High, Medium or Low speed set by remote control.
• Auto Fan Speed
When operation start, or shifting to thermostat ON condition from thermostat OFF condition, indoor fan operates as below.
11.5.3. Odour Cut Control
• Odour cut operation removes the odour generated at indoor heat exchanger by using drain water come out from indoor heat
exchanger.
• Press “Odour” button at remote control to enable odour cut operation.
• Odour cut operation starts when compressor or thermostat is on.
11.5.4. Freeze Prevention Control
• After compressor starts operation for 4 minutes, the outdoor unit will stop its operation if indoor pipe temperature falls below 2ºC
for 6 minutes.
• After 3 minutes stops, compressor restarts operation if indoor pipe temperature is 3ºC or more.
• This phenomenon is to protect the indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid from
returning to the compressor.
