It is designed for both simple and very complicated applications with user-friendly control. It controlls also output of electric heating bodies due to required temperature course which is contained of time intervals and required temperature created by the user. As a standard, intervals from 1 min. up to 24 hours and 7 programmes can be stored at a time with lengths of 1 min. up to 24 hours.
