Because 24v Heavy duty motorized damper has 5nm motor with clutch and timer power off function . When zone fully closes and fully opesn 24v gets cut off. Meaning it's got timed power off function . Also automatic default zone function is to ensure a zone is always open and easy plug in cabling with self diagnostic faulty indicator to zone motors. Simply the best! Sydney wide.

I would like to use something more user friendly , the round gas ones seem ok in principle but are not directional also the larger ones used in bigger spaces tend to sag off the ceiling plaster on one corner due to the above . Im not heavy handed either --any help please as you can see by the pic where i have screwed up the corner Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Ducted air-conditioning vents 17Apr 03, 2015 4:33 pm Pulsing – that is a better way to describe it. My work building has the round vents, if I ever get ducted air conditioning install at another house I've already decided these are the vents I will go for. My other complaint with my current outlets is that the pitch isn't adjustable, so in winter combined with my 31 course ceiling height, it is basically ineffective as a heater. The heated air is blown across the ceiling and not down, so all the hot air is trapped at the ceiling. If I walk around with my hands up in the air, my hands are nice and warm, but everything else is cold! Even in the two rooms with standard ceiling height it is pretty ordinary. Very disappointed there. Re: Ducted air-conditioning vents 18Apr 03, 2015 5:48 pm Carter The heated air is blown across the ceiling and not down, so all the hot air is trapped at the ceiling.

Very disappointed there. Sounds like the return hasn't been done properly. The return should be low down, so that the return pulls the lower cold air out thus pulling the warmer air down. You see it all the time where a return has been put in the ceiling.

I wasnt too concerned as I have a dual system with re fridge aircond which is always the weakest link. If everything else hasnt been designed properly then I guess it will only make things worse. Because of the air cond the system I had to have good airflow. If it didnt then there could be further problem.
