The controller is designed for comfortable control of the autonomous electric room heating system with the possibility of programming the operating modes for a week (operation of the electric radiator in four heating modes according to the schedule of 1/7 days). Programming of modes is carried out by means of a push-button interface. Multistage control of the system serviceability (including the presence of grounding) with the display of error codes allows to quickly and accurately determine the cause of malfunction and eliminate the breakdown. All operating modes are indicated by 4 significant LED indicators. The controller is equipped with two analogue temperature sensors and has freeze and overheat protection as well as a digital real time clock (with power backup for more than 1 year);
