INTRODUCTION
Easy and easy compact are electronic microprocessor controllers with LED display, developed for the management of refriger-
a ng units, display cabinets and showcases. They exploit the experience and the success of the previous PJ32 range, with the
objec ve of o ff ering a product that is simpler and more economical.
The structure of the parameters has been enhanced with new func ons for more dynamic and e ff ec ve management of the
temperature control and defrost. easy compact the smallest, most economical easy model, with one relay only, and a simpli fi ed
display.
