Ive been having issues recently with some danfoss optima condensers with high subcooling “over condensing”.

we are planning on fitting fan speed controllers to delay the fans running in low ambients but is there a rule of thumb when setting these?

Im after a quick reference to set them up quickly and then fine tune once running.

is there a temperature you lads are using so I can quickly check on a P-T chart and set accordingly depending on refrigerant.
