In a typical application two 0–10 V outputs modulate proportional valves and the third drives an EC fan, while the five relays cover stepped speeds, valves or lighting as needed; whatever is not used for HVAC can switch other loads.\u003c\/p\u003e\n\u003cp\u003eThe two inputs take pushbuttons, window contacts or alarms, or NTC probes (TS01A01ACC, TS01B01ACC, TS01C01ACC, TS01D01ACC); input 1 can alternatively host the SM03E03ACC plug-in (temperature, humidity, CO₂, VOC) or SM03E02ACC sensor. Two 2-stage PI thermostats drive heating, cooling, 6-way valves and 2\/4-pipe fan coils, and a compensation-curve function adjusts supply temperature to outdoor conditions. With 8 logic blocks, the Virtual Holder occupancy logic and KNX Data Secure, it is the current-generation choice for hotel and office fan coil zones.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e3 x 0–10 V outputs (galvanically isolated, ±5 %, 2.5 mA each, 7.5 mA total) for proportional valves and EC fans\u003c\/li\u003e\n\u003cli\u003e5 relays 16 A cos φ 1 at 230 V AC: K1–K3 group max 30 A, R1–R2 group max 25 A;
