Hi there

I asked terminator to look into this for me.

The outdoor fan runs constantly throughout the cycle.

Filters are clean, fan speed is set to low but this is because the unit will cycle off even quicker due to being oversized slightly. Never have to run the fan at full speed unless the room temp has difference of 10C off set point to warm up quicker.

Why does it have to be on high fan speed? Surely if its on low then the outdoor unit is isnt having to work as hard to get heat from the air as the heat is being put indoors slower due to lower air flow? Surely the higher the fan speed the more current the outdoor unit draws as the heat is being rejected indoors a lot quicker???
