It is the standard way to run radiator valves, underfloor-heating manifolds and zone valves from the panel: each output drives up to 3 valves at 24 V or 4 at 230 V in ON\/OFF or PWM mode, and outputs can be paired for 3-point valves.\u003c\/p\u003e\n\u003cp\u003eThe inputs make it a complete zone controller. Inputs 1–4 take pushbuttons, window contacts or NTC probes, and the device hosts up to 8 complete 2-stage PI thermostat modules (4 linked to the probe inputs plus 4 additional), so a hotel floor or a small office can be regulated without wall thermostats. Eight logic blocks with proportional-control and dew-point algorithms round out the application.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4 Triac outputs, 24–230 V AC 50\/60 Hz, 500 mA rated per output; configurable as 4 ON\/OFF or PWM valve channels or 2 three-point valve channels\u003c\/li\u003e\n\u003cli\u003eUp to 3 thermoelectric valves per output at 24 V AC or 4 at 230 V AC (4 A inrush limit per group of 4 outputs; use activation delays to stagger inrush)\u003c\/li\u003e\n\u003cli\u003e4 dry-contact inputs for on\/off, dimming, shutters, scenes, sequences and step commands\u003c\/li\u003e\n\u003cli\u003eInputs 1–4 configurable as signalling-LED outputs (LD00A01ACC \/ LD00A11ACC) or as analog NTC probe inputs (TS01A01ACC \/ TS01B01ACC)\u003c\/li\u003e\n\u003cli\u003eUp to 8 thermostat modules in total, each 2-stage with integrated PI controller for heating, cooling, valves and 2\/4-pipe fan coils\u003c\/li\u003e\n\u003cli\u003e8 logic blocks with logical, threshold, algebraic and conditional operators; proportional control and dew-point algorithms\u003c\/li\u003e\n\u003cli\u003eOutputs grouped [1–4] and [5–8]: one supply voltage per group, first output of each group must be wired\u003c\/li\u003e\n\u003cli\u003eFront buttons with logic interlock for manual output switching; channels pre-paired for 3-point valves before ETS download\u003c\/li\u003e\n\u003cli\u003e4-module PC-GF DIN housing; 250 group addresses \/ 250 associations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003eVia KNX bus, 21–32 V DC (SELV)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent consumption\u003c\/td\u003e\n\u003ctd\u003e≤ 15 mA (8-output version); ≤ 10 mA (4-output version)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTriac outputs\u003c\/td\u003e\n\u003ctd\u003e4; 24 V AC to 230 V AC, 50\/60 Hz; rated current 500 mA per output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInrush current\u003c\/td\u003e\n\u003ctd\u003e4 A per group of 4 outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax valves per output\u003c\/td\u003e\n\u003ctd\u003e≤ 3 at 24 V AC; ≤ 4 at 230 V AC (depends on valve manufacturer inrush)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (digital mode)\u003c\/td\u003e\n\u003ctd\u003e4 dry-contact inputs (SELV circuits); scanning voltage 3.3 V DC; max cable 30 m (98 ft) twisted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (analog mode)\u003c\/td\u003e\n\u003ctd\u003eNTC probes TS01A01ACC (-20 to +100 °C), TS01B01ACC (-50 to +60 °C); max cable 30 m (98 ft) twisted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermostat modules \/ logic blocks\u003c\/td\u003e\n\u003ctd\u003e8 \/ 8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminals\u003c\/td\u003e\n\u003ctd\u003eMax 2.5 mm² (approx. 14 AWG) solid or stranded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGroup addresses \/ associations\u003c\/td\u003e\n\u003ctd\u003e250 \/ 250\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN rail, 4 modules; LV distribution cabinet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure\u003c\/td\u003e\n\u003ctd\u003ePC-GF, IP20 (EN 60529)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature\u003c\/td\u003e\n\u003ctd\u003e-5 °C to +45 °C (23 °F to 113 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage temperature\u003c\/td\u003e\n\u003ctd\u003e-20 °C to +55 °C (-4 °F to 131 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative humidity\u003c\/td\u003e\n\u003ctd\u003emax 90 % non-condensing, indoor use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEN 63044-3; EN 63044-5-1 \/ EN 63044-5-2; EN 50491-2; LVD 2014\/35\/EU; EMC 2014\/30\/EU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eKNX certified; CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eETS application\u003c\/td\u003e\n\u003ctd\u003eHAxxA01KNX heating actuator application\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (net)\u003c\/td\u003e\n\u003ctd\u003e0.26 kg (0.57 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part no. \/ GTIN\u003c\/td\u003e\n\u003ctd\u003eHA04A01KNX \/ 8054144521152\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003eSibling: HA08A01KNX (8 Triac outputs, 8 inputs).
