Hi all,

A quick ask re: an Aermec water chiller.

I have an AL75 alarm showing on the Carel controller stating "Anti Freeze alarm"

Since up'ing the water temp set point this alarm is no more.

A general rule of thumb, what water set point would be adequate for a chiller serving a commercial/retail building? I've been advised that anything lower than 9 degrees is more for processing applications, please advise?

Thanks
