That's exactly the unit we just had installed. On the 43 degree day last week, the place was comfortable within 10 minutes after switching on around midday (we live on the South side of a steep slope and don't feel the heat until later than most).
We used the old return air grille slot, which resulted in 85X36 intake area. It whistles a bit with the fan running on full. With the fan on auto and only the downstairs zone running, you would not know it is running. Instead of the wifi Airzone, we use a wall-mounted controller (RC-EXZ3A) with Intesis added for wifi. Unlike remote control systems, changing the AC Cloud app results in the wall-mounted controller updating and vice-versa.
For a simple controller, there's a lot to learn. Zones seem critical and I am yet to work them out. Standard naming is zone 1, zone 2, etc. I can't work out how to name them. We only have three zones configured. The fourth switches to 'SPL' (spill) if you turn off zone 1 (downstairs) and only want bedrooms on. I have no idea of the impact of that on running costs and suspect the spill runs into zone 1.
I've got a café restaurant, the kitchen is the main hotspot, literally. We're cooking up 200 to 500 meals on the weekends, so it gets pretty toasty. Dining area is afresco so can't cool that I think. And then there's the middle pass-through retail shopping area, about 8m by 6m, which also needs some cooling. I'm thinking a multi-split system would be the way to go. It's versatile, so I can target both the kitchen and the shopping area with the same system. Mitsubishi's got this SCM100ZS-W Multi Set on sale. It's a multi-split with a 10.0kW capacity, perfect for handling the heat in the kitchen and keeping the shopping area comfortable too. What do you think?
Got my local Bunnings to price beat by 10% + another $40 for opened box, but was last unit.. Thanks Gokku !
I've got this classic Queenslander house, two stories with lots of woodwork, so it's pretty open and not super sealed. It gets a bit warm in the summers, especially in a few rooms, but not so hot that I need to cool the whole place just yet. I'm thinking about a solution that lets me cool some rooms for now but gives me the option to expand to the whole house later if I need to. With this Mitsubishi sale, I'm eyeing the FDUA140AVNXWVH-Set from their FDUA series. It's a ducted system with a 14.0kW capacity. Seems like it'll do the job for a few rooms now and has the muscle to handle the whole house when I'm ready to seal it up better. What do you think?
