Setting a Second Set Point: LAE AT2-5 Digital Controller

The AT2-5 controller from LAE Electronic features a second set switching mode. This is often used in chillers to manually switch to an extra group of freezer settings when a button is pressed.
This video explains how to activate this mode using the iiSM parameter as well as set the required set point, differential, evaporator time and defrost frequency.
