Do you have an 1800 BTU or 18000 BTU system? Did you have to have the system installed by a professional or were you able to do it yourself? Did you notice a dramatic difference in your electricity bills after the upgrade?
it has an inverter, so the system seems pretty efficient, it doesnt crank up the temp to the setting on the thermostat, then wait and kick back on hard once the temp drops below a certain point.
Read up on the inverter models, they are pretty trick, the one I have .. the outside unit is very quiet.. I love it! 18000 btu, I dont know the power draw, sorry, but it doesnt seem excessive. I have solar panels and my meter spins backwards with the house AC and the ductless split unit running at the same time, and it's FUCKING HOT!
also, I installed it, the outside unit comes pre charged with coolant, you hook up the lines, and there is a shraeder type valve, like on a bicycle, that you drain air out, you dont need gauages, it's a trip. Probably the most difficult part which wasnt even difficult, was properly wiring mine with flex conduit to the garage where I had 220 run. Some run on 110.
As Potlike stated, there are videos and the internet to help you install or build or make just about ANYTHING.
I checked the specs and that controller looks SWEEEET! Do you have any likes/dislikes about it?
likes: everything
dislikes: price ......... I think it set me back 630 dollars. (or something very close)
