Hi guys,

Now it seems Panasonic models sold out. And seems all new aircons now all using R32. Can I check why I see most halls and master bedroom using cassette type aircon. I don't know why as the build in pipes all conventional type ones. Any special benefits to cassette type?

Also anyone selling Mitsubishi Inverter GR and LN series in this thread. Can PM me price for 1 and 1.5 HP, please tell me installation how much too. Thanks.

Anyone using sharp non inverter 1hp, so far so good?

planning to buy one

Here is the panasonic inverter 1hp current usage from my HA. Can see the step up and down when room temp archieve .[attachmentid=10851449]

Hi there all, any alternatives to Hitachi and Sharp Inverter Models?

I was recommended 1hp inverter aircond with BTU >9700, with these 2 models Sharp AHX9VED2 and Hitachi RAS-X10CJ, however no stock.

Any other model numbers to recommend? My room is Bedroom 2 14 ft x 7 ft. Ceiling height 2-3m?

Interesting. Would you mind to shed some light on how to get this reading?

I am using 1.5 and 2.5 XU units from Panasonic. The mobile app is pretty good but the only drawbacks are some times the app is down due to server issues and it can't store more than 6 different timers per day. Loved the WiFi remote control although I had to pay for one of it since it didn't came as complimentary gift anymore. My electricity bills reduced as well from using 1.0 x 2 units of non inverters.   

Recently I've bought 2 penasonic 1.5 & 2.0 XU series AC from lazada by using save 2.0 voucher and 3 units Panasonic bayu 5 fan.
But I found that, a lot of shop are out of stock for Panasonic products, not sure what happened to Panasonic. What's wrong with Panasonic now?
I prefer to have same brands for whole house.
So still need to buy 4 fan, 2 wall AC, and 1 cassette. But suddenly feel x confident with Panasonic. lol
I asked few shop nearby my house, all Panasonic AC out of stock too.
So I scare the Panasonic spare part might difficult to find in the future, was thinking to continue buy Panasonic AC at lazada or change to other brands.
Any suggestions? Or any recommended brand & model for AC(1hp & 1.5hp wall and 2.5hp cassette?

BTU  should not be the  only criteria  to select an invertor  AC . 

the only advantage  is  it  will  achieve your  SET  temp  faster  . 
doing a rough calculation  maybe  about  1 minute  difference.
after that ...during normal operation  its of no advantage .   

Ahhhh okays. What else I can consider?

Paging for sis ceo684, my neighbor was telling me... he did re-wiring of his airconds cause his installer told him its better to wire from 20A switch --> IDU --> ODU instead of the wiring developer gave which was 20A switch --> ODU --> IDU?

Would it make a differences? So far I got quotes from 2 shops which came to see... none of them commented on this wiring topic.

Usually power goes to IDU nowadays but it depends on the specific aircon model tho, older ones tend to put the master at ODU. Usually the power supply goes to IDU as master controller (nowadays) and power fed to ODU by IDU by a connecting cord.

my neighbor told me that from supply to IDU this way the aircond connection more reliable... then I checked with the electrical subcon, was informed the cassette mounts are supply to ODU while the wall mounts are supply to IDU instead.

Is it cassettes are usually supply to ODU? or maybe aircond units nowadays can do either configuration?

No they cannot  do either configuration  . 

either the IDU or ODU   will be the  power control  depends on the design . electronics design. 
best to check on the installation guide for the AC .

Depends on aircond power/hp. Some high hp aircond need 'direct' supply for ODU.
Most probably cassette is hi hp type, so need direct power supply for compressor.

Something like this.

For any A/C with 3.0 HP and above, usually power goes to ODU.

It all depends on the AC mfg, some Daikin cassette 2hp also power to ODU.
It is normally shown on the spec sheet or installation manual.
