The E-Top HR-02 KNX multizone wiring controller adapts to diverse space scales with flexible 8-zone or 16-zone control options—8 zones suit medium-sized areas like 3-4 bedroom houses or small office floors, while 16 zones cater to large-scale spaces such as multi-floor hotels, hospitals, or spacious commercial buildings. Its core strength lies in centralized wiring design: all thermal actuator, circulation pump, and boiler wiring is routed through one controller, eliminating scattered connections to cut installation time and simplify maintenance, plus it includes dedicated outputs for circulation pumps and boilers to ensure synchronized operation (e.g., activating pumps/boilers only when a zone needs heating to avoid energy waste). The controller also offers broad compatibility, working with any KNX room thermostat on the market, and each zone can connect up to 5 thermal actuators—allowing fine-tuned heat distribution within a single zone (like adjusting heat for different parts of a large living room or office) to boost both comfort and efficiency
