Also inverter starting was runing slow speed to maximum JET speed vs non inverter full load power.

hehe..you see the pictures posted on this forum..
i see plenty of the contractors drill through the beam so the wire can go through 

No battery leak in remote control, still very clean inside. What kind of shop sells universal remote? Does any electrical appliance shop sells this?

Guys,

I'm asking opinion on placement of 2 AC outdoor units.



Currently preferring Option A.

Thanks.

Look like Pana out of quality control.

Exported to thailand made lagi better than localized quality control cut here & theres

So next time no more cheaper Pana brand already..

Did Pana going to improves thier remote control and add in easy clean design for more customers choice

Against Pana always do facelift design from previous model they call it patrol control of that sensor turn on blue LED light to spoil my dark room and my eye always keep on that blue light, at the end I had do DIY for apply tited in black color for cover up that few LEDs light on FCU.

Actually they no points to keep so much LEDs light.
As a good design for only power on green color will do.

Last time we knew national is the best Aircon n also much expansive.
Like compressor is original come from Japan then the rest just packaging in malaysia by matsushita under japanese company.

Now compressor n parts all made in China and just the casing and packing from pana malaysia only.

Using the diagnostic function it states error code f91. Googling that up i came up with:

Abnormality / Protection control = Refrigerantion cycle abnormality
Abnormality Judgement = 2 times occurance within 20 minutes
Emergency operation =
Primary location to verify = • No refrigerant (3-way valve is closed)
Well it was blowing out air. Noticed it wasnt cold but the contractor said it will take some time for the compressor to work and its a hot day. Turned out it didnt change until night time when i turned it on again.

Just received the MHI 1hp inverter air-con SRK10YL-S4 today, read the manual, found out that the MHI inverter air-con needs 7 wires (3 wires to the out door unit, 4 wires from the out door unit to the in door unit), any one can confirm the needs of 7 wires?

My current Panasonic inverter Cs-S10NKH needs only 4 wires...

Thanks ozak and weikee.

"Most installer will tap the power from indoor, and go to the compressor"... Is this safe?

The leaflet was indicated 4 wires only... But the manual wiring drawing needs 7 wires 

Pana inverter so far has many Aircon shop not recommended, due to easily failed.

Cause power supply located indoor side n taken too much standby power for the board itself and easily made on overheating burned.

So they recommend me on non-inverter Gas R410a Pana brand, more durable and just 1pc of PCB to control in/out.

But the manual drawing of wire shows 3 wires to outdoor unit, 4 wires from outdoor to indoor (seems the MHI design the 'control of air-con' is from the outdoor unit to communicate to the inddor unit), the contractor needs to pull 7 wires to match the wire drawing. Unless change the wiring as per attachment (red wire is for communication between outdoor and indoor unit, but no control of power supply from outdoor to indoor unit).

Btw, the leaflet stated 4 cores of wiring.

Panasonic's wiring seem much simple...

btw, I opened the outdoor unit and check, can only find 4 slots for wiring, I expect 7 slots... as per the manual...    Will call the MHI main distributor and confirm again.

They need to pull 3wire from the db for supply (3 wires from DB to outdoor unit). Than another set of 4core wire tie together with the piping to the indoor unit (4 wires from outdoor to indoor unit) = pull 7 wires ?

Noted and thanks.
Checked, there is only one terminal box in the outdoor unit... spoke to MHI distributor and just found out that the wire terminal is having two layers (2x live, 2x neutral, 1x signer between outdoor & indoor, 1x earth).

Look like MHI needs more wiring... means more $$...

Standby power like a once you turns off the Aircon.
If switch of main plug to be totally don't have keep standby power mode at all.

No sure it is parallel join....

Just received the confirmation from MHI distributor... the wiring should be as the photo.

Thanks for the explanation. If it is parrallel, does it means only needs 4 wires?

Thanks, my contractor said 4 wires will do  He said the air-con on/off switch linked to the indoor unit (3 wires - L, N, E), the same 3 wires will linked to outdoor unit + 1 wire for signal link between inddor & outdoor units.
