The Eelectron HA04A01KNX is a 4-channel KNX heating actuator for thermoelectric (electrothermal) valve drives, with 4 Triac outputs that accept 24 V AC or 230 V AC actuators and 4 dry-contact inputs on the same 4-module DIN device. 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.

The 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.

Key Features

  • 4 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
  • Up 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)
  • 4 dry-contact inputs for on/off, dimming, shutters, scenes, sequences and step commands
  • Inputs 1–4 configurable as signalling-LED outputs (LD00A01ACC / LD00A11ACC) or as analog NTC probe inputs (TS01A01ACC / TS01B01ACC)
  • Up to 8 thermostat modules in total, each 2-stage with integrated PI controller for heating, cooling, valves and 2/4-pipe fan coils
  • 8 logic blocks with logical, threshold, algebraic and conditional operators; proportional control and dew-point algorithms
  • Outputs grouped [1–4] and [5–8]: one supply voltage per group, first output of each group must be wired
  • Front buttons with logic interlock for manual output switching; channels pre-paired for 3-point valves before ETS download
  • 4-module PC-GF DIN housing; 250 group addresses / 250 associations
