There are two adjustments screws, a small brass one apparently moving

One screw will be for the temp setting, the other to vary the
differential (or hysteresis) between switch on/switch off. (Ie to stop
it coming on and off too frequently)

Some fridge compressors don't like being started until the gas
pressures have equalised, so the differential needs to take this into
account.
