Fujitsu Lifestyle ASTG24KMCA (7.1kW / 8.0kW) Questions & Answers

Hello Jason. The 7.1 kW sure is a powerful one ! I also reckon you get an expert to give an opinion. If you get the wrong one your electricity bill could be astronomical!!

I leave mine turned on all year, there is no need to turn the isolation sw off unless for maintenance.

Hi, I only placed a review on the aircon, I'm not a serviceman.
Would suggest you contact the original installer of the system or call the Fujitsu trouble desk.

Can the KCMA be fitted with a WIFI Module?

Anil, I've had this on my non wifi unit since I brought it, works perfectly.

Auto it adjusts room temp when reached wanted temp

And COOL will cool to set temp. DRY will remove humidity only, but it will make the room feel cooler as a result- this is great when humidity is high but temperature is not.

Thanks Eri and Lyn. The instruction book just gives the bare basics, with no explanation of what each mode actually does. It's as I thought, but wanted it confirmed. Thanks again. Mel J

Most remote controlled HV seperate economy & powerful buttons,temp required buttons,& auto settings.And most do auto rise & fall when room areas HV reached temp settings.

Yes mine does this. However, I am into home automation and am using a controller that can turn it on and off remotely using my mobile from wherever I am.

Yes, you can set daily on and off times with the remote... the problem being is once it reaches the set temperature the unit switches to economy mode... but it never powers back up once the temperature starts rising again... example I switched it on about an hour ago as its going to be about 40c today.... the lowest setting is 18c so unit was switched on, it has cooled to 18c and has now switched to economy..... give it an hour or so and the temperature will be about 25 and climbing but the unit wont power back up again... come 3pm if I dont press the powerful button about every 30 minutes it will be about 35c inside

No it sounds that younhave a pr9blem i would contactthe manufaectors custoervservice who are very helpful

The installer said i had to keep on for v 1-2 then turn off he stayed untilmi understand how to,use it i used a8rtasker to,install

Sounds to me as though there, is a problem with the unit and I would be contacting the warranty branch immediately. My unit takes a little while to actually operate after being turned on but that is normal. Mine can be too cold if I don't watch it or too hot if I have it set too high. I love it and it's worked perfectly from day one.

At colder temperatures, where the outside unit coolant temperature is below freezing (where it is near 0oC or below outside), the unit collects ice on the compressor coils and has to stop heating to defrost the outside coils (because it become ineffective at transferring heat to the coolant which is condensed to heat the inside air) and restore the ability to transfer a usable amount of heat from the outside air to the coolant, and from there use the it to heat in indoors. When it does that, it shuts down the blower inside, since there is no or little heat residual. Once the outside coils are defrosted (don't know if the unit can sense that or just goes through a fixed time cycle) by the electric heating elements in the outside unit, it restarts automatically. It will periodically go through this cycle as ice continues to build up. At the times it is going though these cycles, it is much less efficient and may be more expensive (i.e. use more electricity for a unit of heat) to run than an all electric space heat. I have not been able to get the information from Fujitsu on the efficiency at low temperatures, so do not know at what temperature point the unit is more expensive to use for heating the a $15 electric heater (it doesn't depend on the price of electricity, since electricity is used in both processes, but does effect the cost benefit of the unit.

It's just making sure not to blow cold air at you and defrosting, it's completely normal and you can buy a base heater that uses a little electricity to help keep the units a bit warmer and may help with this a little.

Hi Ian
Unfortunately there are no other instructions that I'm aware of. The ones provided are complicated, but that's all that is available.

The model we have is the 5KW and we use it on low to cool a large kitchen dining and lounge area. It could also be used on high if required. Certainly the 7KW would cover this area very well. Hope this helps.

I can't honestly answer that question, as our whole cabin is only 8m by 4.4m. We get the benefit of the cool air in both the bedroom and bathroom, the two farthest rooms from the unit when the door to them is open. And it keeps the cabin cool, even thought it has very limited insulation and very high ceilings. We set it to 23* so not on cold but we certainly notice the difference from the outside temperature! I hope this helps.

The "open plan" kitchen-dining-living room we have it in is approx10m x 10m and it can easily fill with cool air on the medium to higher settings.
