BF-170M is a type of pressure-bearing solar water heating system controller with a high-power contact output of 3000 W, consisting of a main unit used to control the entire water heating system, and 5 optional super-slim wall-mounted wire controllers to be connected to 4 different water consumers in order to allow users for long-distance regulation of the main unit.
In order to meet various demands of controlling water heating systems, this product is integrated with two groups of functions, i.e., heating control functions (timed auxiliary heating, heat collection circulation, manual heating) and water return control functions (timed water return, manual water return).
This product features a higher versatility and enables customization of control scenarios and parameters according to individual requirements.
BF-170M is an ideal solution for detached townhouses, residential houses, resort hotels, inns and other applications, and able to ensure large-capacity heating operation with stable and excellent performance.
