Browse Forums Heating, Cooling & Insulation Re: Actron ducted ac efficiency 3Dec 23, 2017 2:09 pm I’ve checked the manual I don’t think I can adjust the throttling temp. The a.c controller is in the hallway below the air filter I’m assuming the temp sensor is inside the unit. I think it’s a dumb spot as it’s directly opposite my main bathroom which for some reason is always hot and humid even though it’s insulated the same as the rest of the house. My only guess is the hot roof air enters the bathroom through the fan vents. Our master ensuite though never seems to be humid. I try usually closing the sliding door to the bathroom with the air on but as soon as you open it you can feel the hot humid air. Re: Actron ducted ac efficiency 4Dec 23, 2017 2:33 pm Any adjustments to throttling range would be an installer setting and not detailed in your user manual, hence the suggestion to contact your installer. What is the brand of unit? Some brands can be changed to control from either sensor bulb in wall controller or return air sensor. If your exhaust fans in the bathroom don't have barometric or shut off dampers, maybe you could retrofit these http://www.draftstoppa.com.au/draftstoppa. Is your main bathroom on the western side of your house? Re: Actron ducted ac efficiency 5Dec 23, 2017 2:47 pm It’s an Actron Sra 153c 14.7kw net reverse cycle. Wat size would this ac suit as originally the house was 25 square but due to promo it got upsized to 27 square. I also paid extra for 2700 high ceilings. Re: Actron ducted ac efficiency 7Dec 31, 2017 11:43 am Interesting I found a formula on what size a/c one should purchase to adequately cool a home. My house is approx 260metres square so they estimate wih 2700high ceiling you should have 150 watts per metre square. This equates to 39000 was or a 39 kilowatt system. Yet the builder supplied us with a 14kw system 3 zones and advised only 2 zones are to be used at any one time even though f we want we can run 3 zones. The other stupid thing is the installer has done the family room as our big open area whereas they could have change dit around and had one zone cool a small room with a door on it instead they now have one vent to cool a massive area or I can turn on another zone to cool the same area. how dumb Re: Actron ducted ac efficiency 8Jan 09, 2018 9:34 pm 6banga Interesting I found a formula on what size a/c one should purchase to adequately cool a home.

In addition, there are rooms which you do not necessarily have to cool (e.g. garage, storage, etc.). Also, it is highly unlikely would need to cool all the bedrooms as well as living spaces at once.
