Hi Steve
From memory all the Eurofrigo units that used to work on overshot the set point. The important bit, for me, was that they cut out. I compensated by adjusting the set point accordingly.
I used to have wiring diags, etc, but left them behind when I left UK.
Out of interest, I guess from your user name, you are with a Carrier dealer.
If you are Steve A...... please PM me! Got some catching up to do!

Is it controlled by an electronic controller?
Does it cut out at SP (-) Hysteresis

If so the controller is possibly set up for heating and the relay contacts (Change over) are reverse wired.

A normal refrigeration control cuts out at SP and cuts in at SP (+) Hyst.
