My power supply is installed near my Daikin indoor unit and so far it works flawlessly. The air-cond installer that I deal with is no professional. He just keep quite and looks like doesn't want to talk to customer.

I set >26c because it uses less energy as claim by many inverter type air cond manufacturer.

26c, better use natural air outside in the evening. Way to stuff for me. Maybe is only me. I use A/c for <=23, else i just off it.

My room exposed to the sun in the morning until afternoon. It's very hot and ceiling fan alone is not enough. That's why I opted for air cond. 26c is fine for me

Btw, how come inverter air cond compressor also will stop spinning like non inverter? Shouldn't it spinning at variable speed without stopping?

Why is that the power supply for the aircon? Never see before.

Hitachi inverter aircon also does the same thing if the temperature is set to higher such as 26c, when the aircon sense the ambient temperature is lower than your room and the aircon doesn't need to cool the room anymore, hence it shutdown to further reduce the energy use, when it start back again, it still under partial load not like traditional aircon which does full load running.

Dunno, this is what I was told by my concealed piping contractor, my electrician, my wetwork contractor (ex-aircond installer) and Daikin telephone service technician helpdesk.

It doesn't matter is stop or run at low rpm. As long as it save bill, I m happy.

This aircon manufacturing will use many way to program the controller to optimise what best way to save. So different brand have different way to program run the aircon.

Normally a power supply is mean a voltage regulator converter from AC to DC or high to low. Or in consumer way we call driver.

Any indication on the price and where to get?

Sharp, so far so good Cheap too. about 800+- when I brought one.

I'm curious about my inverter aircon wiring. Can help me to take a look? Is it done properly? It seems like my power cable is being connected to the indoor unit and the installation manual stated it should be connected to the outdoor unit. Correct me if I'm wrong.

Yes. it is wrong wiring. Need to correct the wiring. Most probably the protection unit is at the outdoor unit. So your aircon now don't have protection if anything happen.

Arh!!! I really fed up with the aircon installer. He do job without heart 1... uneducated as well! I think the wrong wiring has something to do with my condenser fan as well coz it operates full load no matter i switch to the lowest temperature or higher temperature.

Normal lah. Most of this aircon man is by experience. They don't even know how to read manual.

Your manual diagram said have 4 wire to your indoor unit from your outdoor unit. 1-Live, 2-neutral, 4-earth and probably 3-signal.

But your wrong connection is parallel wiring. And missing 1 wire to outdoor unit. Either earth or signal wire which is on no.3. The total whole connection is wrong.

its like that one, thats why sometimes need to double check their work one..

just bot a Mitsubishi 1.5hp MS-GF13VC @rm850 cash n carry, i ask for 1.0hp but was given 1.5hp, didn't check and only notice this morning when my a/c man start to install it, got to pay him extra to mod the copper piping too
