The Eelectron HA88B01KNX is a combined KNX valve and load actuator: 4 Triac outputs (24–230 V AC) for thermoelectric valve drives, 4 relay outputs rated 16 A at 230 V AC, and 8 dry-contact inputs, all in a 4-module DIN housing. It is sized for one room or zone of a hotel or office: valves on the Triacs, fan coil speeds or lighting on the relays, pushbuttons and window contacts on the inputs.

The relay block follows the F-series logic, so the 4 relays can also serve as 4 load outputs, 4 PWM valve channels, 2 shutter channels or 2 three-point valves, or be interlocked in groups of 2, 3 or 4 for 2-pipe/4-pipe fan coils with up to 3 speeds. Inputs 1–4 accept NTC probes, up to 4 complete PI thermostat modules run inside, and 7 logic blocks handle the rest of the room logic.

Key Features

  • 4 Triac outputs, 24–230 V AC, 500 mA each: 4 ON/OFF or PWM valve channels or 2 three-point valve channels
  • 4 relay outputs 16 A cos φ 1 / 8 A cos φ 0.6 at 230 V AC: loads, PWM valves, 2 shutter channels, 2 three-point valves or interlocked groups of 2/3/4 relays
  • Manages 2-pipe or 4-pipe fan coils with up to 3 speeds; unused outputs remain free for other equipment
  • 8 dry-contact inputs for on/off, dimming, shutters, scenes, sequences and step commands
  • Inputs 1–4 configurable as signalling-LED outputs (LD00A01ACC / LD00A11ACC) or NTC probe inputs (TS01A01ACC / TS01B01ACC)
  • Up to 4 thermostat modules (2-stage, integrated PI controller) and 7 logic blocks with proportional-control and dew-point algorithms
  • Manual front buttons and status LEDs for local relay switching
  • Triac outputs share one supply voltage (24 V or 230 V, never mixed); output 1 must be used first
  • 4-module PC-ABS DIN housing; 250 group addresses / 250 associations
