Ello everyone! A bit of help please if you dont mind. my reply is underneath.
How would you explain to this person that setting the unit at 18C will not cool the conservatory any quicker than if it was set at 22/23C?
Thank you.

Got home yesterday and the conservatory was hot. The windows has not been open, as usual. It would have been uncomfortable to sit in for any amount of time.
I switched the unit on - 18degC, high fan speed, random vane directions. Within seconds you could sense the temperature drop, and very soon it would have been comfortable to sit in.
We are not using the conservatory in ernest yet, still awaiting for the flooring to go down. Once it is a living space, I will record my findings then, in the other post.
Thanks

Can I ask why you are setting the unit to 18C? THis is not efficient to use the air conditioner.
If it is 28C in your conservatory for example setting the air conditioner at 18C will not cool the conservatory any quicker than if it was set at 22/23C. The system is already working at 100% output when there is a 3C difference between the set point and the actual room temperature.
All your doing is asking it to cool the room to 18C which would be a very unconfortable temperature... too cold. You have got to cool it to a sensible temperature first.
Set the remote control at a reasonable temperature perhaps 22/23C and leave it.
The only thing that will influence how cool the room cools down is the fan speed, the higher the airflow the cooler it will cool down.
Its the same as setting your central heating at 30C when your house is cold. It doesnt warm the house up any quicker its just a "Set point" the target temperature you want to achieve.
Does this make sense?
Also if your outdoor temperature is cooler than the interior of your conservatory it is more efficient to open the windows and doors of conservatory. Usually in a conservatory this is the case as it is always hotter than outside air.
This means the air con will not have to work as hard as cooler outdoor air will get into the conservatory from the outside and cool it as well as the air con.
It only makes sense to close the doors and windows when your indoor temperature is cooler than the outdoor temperature.
Eg if it is 25C outside yet your inside temp is 22C then you need to keep the cool air inside by closing doors etc.
But if its 25C inside and 22C outside it makes sense to use that cooler air outside also to cool the inside. Doing it this way will save energy and the system wont have to work as hard.
Its the same as if you was too warm in winter you would open the window to let the cold winter air in.
How would you explain to this person that setting the unit at 18C will not cool the conservatory any quicker than if it was set at 22/23C?
Thank you.
