Hello Heta, Sorry to hear that you are having this problem. I will send you some instructions on how we can resolve this for you.

I recently purchased the 7.1 kW Brontë SRC71ZRA-W model instead of the 63 as our summers are getting unpredictably hotter, and the winters, your guess is as good as mine. No regrets in my decision as these units are very efficient and my family and self are very happy with the wise choice. I don’t need to worry about “will the home be cool enough during summer heatwave?” The difference, in my opinion, between your two models are the indoor units as they both use the same outdoor unit, and I think it could be cosmetic. My SRC71ZRA is probably more rectangular-ish than the DXK but whatever it is, you won’t go wrong with the Brontë 7.1kW SRC71ZRA. Just remember that they need to be serviced once every two years to keep them in good working condition, and if you are in Western Sydney, get your unit from Globalrez and insist on having his best installer put your unit up. Kind regards, Romeo Alfa

Thank you for your reply, I have bought the MHI 6.3kW DRK21ZRA-W today for $1,628 (Northern Brisbane). Getting installed for $650 in two days. While the 7.1kW woould certainly have done the job, according to the MHI Room Sizing Chart, the 6.3kW should be sufficient for my needs and in my circumstances (44sqm).

It is replacing a working 7.1kW system (Celestial) that was installed in December 2003. Yes, this is correct, it is 20 years old and it is still working! (it did stop working once when an Asian gecko fried a circuit board in the interior unit many years ago). I attribute its lengevity to the fact it did not get that much use over the last 20 years.... because it is pretty expensive to run. I only used it when it got really hot over summer. When I installed it in 2003 I had an asbestos roof and no ceiling insulation. Additionally, the lounge room I was cooling was exposed to both the morning and afternoon sun. The temp in my ceiling space was over 70C!! So I was trying to cool my interior AND my ceiling space. Not ideal by any stretch of the imagination.

Im 2009 I had ceiling insulation installed (pumped in cellulose fibre) courtesy of the government rebate at the time. Understandbably this made a huge difference to the overall efficiency of the Celestion 7.1kW

About 3-4 years ago my asbestos roof was replaced with a metal roof. Anticon insulation blankets were placed immediately underneath the roof sheeting. I also replaced the cellose fibre with "ceiling insulation batts" (I had to as the cellulose insulation had become contaminated with asbestion during the removal of the asbestos roof). Finally, I installed two whirlybirds to ensure that any warm air in my ceiling space is removed to reduce, if not eliminatre, any heat soak into the home interior.

On the exterior I have installed external sun shades on the eastern side to stop the sun from heating the side of the house. At the same time I had the celing insulation installed in 2009 I planted a wall of golden cane palms trees along the western side of my house which are now 5 metres high and serve as a very effective sunblock. All the shading has greatly reduced the heat soak from direct sunlight, but of course does not stop heat soak through the walls (which are not insulated) from the ambient temperature.

Despite the huge improvements to the insulation of my house, the 20 year old Celestion is still expensive to run. Because it is old technology (non inverter), when it is running, it is running at 100% capacity. So I am biting the bullet and replacing it (at considerable expense).

So hopefully the 6.3kW will be sufficient and efficient enough to nake a significient reduction in running costs. I am hoping that when in use it will spend most of the time using only minimal power as the inverter technology kicks in. Hopefully I can use it more often and have it cost less.

The 6.3kW is rated to operate from 2.3kW to 7.1kW (power consumption being from 0.2kW to 2.5kW). The 6.3kW system's minimum power comsumption of 0.2kW is half that of the 7.1kW system's minimmum of 0.4kW. Only time will tell what the actual runnins costs will be. If I encounter a very hot day, the 6.3kW is actually rated to a MAX of 7.4kW

How long have you had your 7.1kW for? What are your running costs?

Incidentally, I have also purchased a MHI 2.5kW SRK25ZSA-W (installation is taking place tomorrow, $550). It is to replace an 20 year old Mistral 1.3kW split system in my bedroom that finally stopped working earlier this year at the end of summer (It has required repairs 2-3 times over the last 20 years).

I hope that that I get many trouble free years out of these two MHI systems.

Re regular servicing, Why do you think regular servicing is necessary? What exactly do you think needs to be serviced? I never had a regular service performed on either of my two split systems since being installed 20 years ago. Nor did I perform any exterior cleaning of either of the two units. All I ever did was clean the interior filters. So to me regular servicing seems a myth. If properly installed, the system will never leak gas (my 20 year old Celestion unit is proof of that).

Thanks again for taking the time to reply to my enquiry.

Kind regards

Doug

I am also wondering the same ...

Hi Stefano, the models (SRK71ZRA-W & DXK24ZRA-W) are exactly the same, they just vary depending on which reseller you may purchase the unit from.

Hello Garry,

Thank you for reaching out to us. The temperature on the remote does not go lower then 18degrees. This is so our units can work at optimum capacity to cool and heat your desired area.

Can this be changed? I’ve just had one installed and I’m devastated it can’t be set to a lower temperature for keeping the chill off during the night

Hello Brett,

Thank you for your enquiry. Did you mean the temperature that you run the Air conditioner on or the temperature that you can set to turn on when outdoors is a certain temperature?

I believe the Brontë 7.1kW model uses inverter technology. That was my first point of selection, and that was subsequently confirmed by the retailer too prior to delivery. With our rising power costs, we need this energy saving technology to help maintain efficiency.

Unable to comment as I don't know how big your old Hisense is, in comparison to your new 8Kw Bronte and 3.5Kw Avanti. I am assuming that your old Hisense is much bigger in Kw, hence the better heat efficiency. Speaking from my experience with my new Bronte, the high fan doesn't produce higher heat, just better distribution and hence lower in temp. It's my 2 1/2 weeks and I must say I like my Bronte. I close all unused rooms and the lounge room gets warm and comfy at setting 20.. On those very cold nights, I set it to 21, and soon, the lounge temperature gauge tells me it has reached 20, and that's comfy. Regards.

The Hisense was 7kw, which is why it surprises me that the MHI Brontë 8kw does not appear to be as warming and I use the high fan and vent positions for better distribution. The rooms were assessed for the correct MHI unit by the installer before installation. I’ve also read the instruction manual from front to back and all settings appear to be as they should be.

I would first suspect the remote control. When did you last change the battery in the remote? I would do that first, and if it still mal-performs, and as your unit is still under warranty, I would make contact with Mitsubishi. I am not technically minded, and hence would get the experts involved. Best of luck. Regards,

It has been a while.

I’ll try that.

Thank you.

All sorted thanks to Darren from MHI in Perth WA. FYI: Turns out the reason I was having trouble was on my end! The timer function on A/con remote does not work when an WI-FI unit is plugged in. Instead you need to use the AC Cloud app to do it through patterns. I was also trying to access the WI-FI unit through wireless but thanks to Darren I found out that it needs to be accessed first through bluetooth. regards NK.

Hello Harry, Really sorry to hear the issues you've been having. We’d suggest submitting a warranty service request via the page below and we’ll get an authorised service agent in your area to get in touch and organise a time to come and assess. external link 

I hope this has been of some assistance however if you need anything further, don’t hesitate to contact us directly on 1300 138 007.

Yep. Same problem here. In mid winter I have it set to 18 degrees, any hotter and it's way too hot. On a 38 degree summer day I have to set it to 30 degrees to not make it freezing cold inside

Hello MLaw, Thank you for reaching out to us with regards to your remote. I would suggest these few spot checks be carried out first. 1. Please change the batteries , if this still persist ; 2. At the bottom of the remote you will see the ACL button, this will need to be pushed with either a ball point pen or bobby pin, please hold this down for at least 10 seconds .

3. If the above does not result in eliminating the error code, we ask that you do a full restart from your electricity main. Switch off the main power switch for at least 6-8 minutes , once you do a full restart this should remove the flashing signal.

If this does not work, please lodge a service and warranty request by following the below link and a service agent will be able to attend to do a visual check on the issue.

Hi Nothing but the truth, Yes, Mitsubishi Heavy Industries air conditioners incorporate inverter technology, which modulates the compressor’s speed to maintain temperature while keeping power consumption to a minimum. This means they’re super-efficient and ultimately cheap to run!

Hope this helps but please let us know if you have any further questions.
