Ah you see I was surprised to find out it's consumption is that low. Turns out, the aircon isn't on throughout the night. Most of the power is consumed during the first hr as it cools the room down. Once the room's cool, it's just a matter of maintaining that temp. Do note that I set it at 26-27 degrees, which may be warm to some. Also, ambient temps are lower at night., which means u need less power to cool a room down.

I did another experiment in the afternoon. Observed usage for an hour at about 2pm and found the aircon consumed 0.8KWH in that 1 hour.
nevertheless, impressive still! even without the compressor unit turned on, the FCU also consumes substantial energy...

btw, what's your air-con brand? maybe it's time for me to change after-all! My Fujitsu is only 2 ticks... and I'm spending >$300 on PUB bills! Most of it is electricity!
