External stat?

Yes it can be easily done if you know how the control circuit works.
The trouble with AC units is they are built with lots of safety features
to stop the thing if it gets too cold, too hot or a multitude of other reasons.

In principle setting the stat lower is possible but unless the other safeties are
disabled it would trip out on something else.

If you had a system and rewired the control you could easily override the stat
and safety features but just resetting a new stat might lead onto other issues.
As the unit gets colder it starts behaving differently and the safeties are built
in to protect from that.

Thanks for your answer.

The reason i ask is i'm opening a micro pub with a cellar of 7sqm and have been quoted £1500 to supply a chiller that goes down to 11C which is a standard unit to chill a an area at least twice the size required. I can buy a 12000BTU domestic split unit heat pump model for sub £400 pound but they only go down to 16C. As this is overspeced for the size of room I thought it would be well within its capabilities and would not need to run for as long as a lower output unit to reach target temp.

Thanks
