what do u mean controller wire no need bro ?

Aircond is counting like that? No matter i'm on Fan 1 , Fan 2 , Fan 3 ? I remember someone told me that set aircond more than 24C then will save electric  , i didn't use those fancy function , my aircond setting is Fan speed 2 at 25C , so my aircond won't act On/Off i think

Any sifu here can enlighten me either the black wire is sufficient for a 2 HP Daikin non-inverter air-con?
My AC guy did this but my main con ( I engaged them differently) tell me that this black wire is not sufficient for a 2HP air-con. It might get melt in the future.

I assume the grey 1 will be the power supply, and the black wire I have no idea what's inside. My main con suggest me to get a 3 x 2.5mm wire instead of 1 x 3 core wire. He was talking on the black wire.
Let me get an image of the wire head and update here. Appreciate reply from you guys.

*another question: how to make sure the wire is certified by SIRIM and not some low grade wire from china? Just to double check. This AC contractor giving me too much prob and I started to lose faith on them.

Thanks to all the sifus 

My wires look like this
[attachmentid=4226037]

[attachmentid=4226045]

and this taken inside the room
[attachmentid=4226038]

Ya currently the wiremen pull a 20Amp wire for AC ppl, then the rest is taken care by the AC guy.

i plan to install 4 aircon for my unit . 1 of my contractor told me single phrase only recommend to install max 2 unit 1.5hp air con ...

got such thing?

Guys, below is the photo of my condo unit and im planning to install and aircond in the hall

my mistake was not preparing the aircond point before installing the plaster ceiling which is a major headache now


Red is where i would like to place my aircond
Blue is my mainbox

I cant put the aircond at the balcony door due to my plan to raise up the curtain all the way to the ceiling.

My question is:
1) is it possible to put my aircond there?
2) Will there be any permanent damage to my plaster ceiling after they hack it to place the cables?
3) can the air cond wiring go through that beam in the middle?
4) How much will it roughly cost for the wiring works?

Thanks

My bedroom size is about 14'x18'
What is recommended HP?

thinking to buy inverter tyupe either samsung,Panasonic(Econavi) or Mitsubishi( Mr Slim)
Mitsubishi is the most expensive

If i choose 1.5HP, will it be any issue?
--> eg: extra current usage to cool down the room especially inverter type
I understand that 1.5hp might not sufficient to cool down the whole room
My thinking is as long as bed area is cool, it is ok for me

Attached is my bedroom plan drawing

Face wall means that bed head facing air cond wall is it?
My concern on HP1.5 is that even though bed area already cool but compressor still work hard to cool the entire room.
On other words, it can't reach desired/setting temperature
Thus extra work out for compressor lead to extra current usage even though i choose inverter type
Would like to know whether my concern is correct?

HP2.0 too expensive though

Why no samsung =( , i got 4pcs ac for my whole house

will die after 3 year?

I'm using panasonic all across my house. And I kinda agree with you. I've got two 1 hp and one 2 hp. Not having wind slowness problem but keep needing to service I dunno whether its because not installed properly (the air cond contractor told me the initial installation was not proper and the water kept flowing back and causing freeze). Thing is i have fixed that problem but it seems the damage is permanent...it just doesn't function well now

what is the different between mitsu electric and heavy industries?
which one better?

Samsung very noisy one la the outdoor

prob is inverter got 1/2hp? my room is only 10*10 liao. small room 1pk is a waste of electricity

which is the most accurate aircon HP calculator?

So which one is cheaper and which one is more reliability?

Do you knew why ppls who invest Aircon for improve their sleeping as well, do you know that?

Very simple one day we works hard but for our sleep at night is really most most improved than you works hard.

From 5-8 hours per days at night for sleep with Aircon even your dream also turn become more sleep drame Leh..

Believed me.. Fast going to install next month you would realise your life got Aircon is really like a boss..

Later you much thanks me.

Wall/ceiling fan is already out dated in 2014 today..

Sorry, Industries is more cheaper or more reliable?

Pana cooling fins dirty up easily.... How to clean it? I tried using paint brush but still cannot take out the dirt

really meh? somehow I do realize your post make me remembering myself now very sleepy whole day liao.
Is it because aircon or lack of exercise? because when I sleep in hotel or when I am in Singapore sleep on aircon walau sleep only 4 hrs but more energetic than I sleep 8-9 hrs like now.. I have already bought new spring bed still same liao even with new spring bed after alarm tend to sleep again because feel too cozy. I am a dilemma now. someone can verify that kimsim's statement is valid?

thank you thank  you for make me to fork out more money on aircon liao 

But aircon creates dry air.it's good for my allergic than humid air. People using aircon live longer.eg: singaporean and japanese

Allergic from child and had asthma. Lucky ate bat and swimming so become better. Just every morning got humid in my nose
