BF-3030, featuring compact construction but powerful functions, can be widely used in solar water heating systems, solar and heat pump water heating systems, etc.
The controller enables the timed heating and water feeding functions respectively to be performed in three defined time segments (i.e., cycles) every day, and allows users to set the water level for each timed water feeding cycle separately.It also features some other important functions, such as thermostatic water feeding, forced water feeding at low water level, and protection against dry heating in case of water-shortage.
The current water temperature, current time, and current water level can be displayed in real time during operation (the water level is displayed in 4 colors).
With the manual water feeding and manual electric heating functions, it is able to ensure easy system commissioning and manual intervention.
Thanks to the wide range of rated power supply, the controller is able to ensure stable, reliable and durable operation by adapting to AC80V~240V power supply.
