Auto AHU — User Manual

Auto AHU helps you build an AHU (Air Handling Unit) display screen without drawing it by hand. Build the unit directly in the preview, then export a ready-to-use display.

1. Settings

Open Settings (top right). Everything there is saved in your browser:

• Display size — width and height of the atvise display in pixels.
• Modbus table — the controller type your unit uses (currently: Carel).
• Node path prefix — the base address for your project (e.g. AGENT.OBJECTS.Klimat). It is put in front of every register, so you only set it once.
• Icon library — the atvise folder holding the icons (default SYSTEM.LIBRARY.PROJECT.OBJECTDISPLAYS.6.%20Ikone).
• Icons — the object display name used for each component. Leave a name empty and the icon is drawn straight into the display instead.

2. Title and heat exchanger

• Title — click the title in the preview to rename it. Press Enter when done.
• Heat exchanger — click it to choose Plate or Rotary, or to centre it. Drag it left or right to move it; double-click it to centre it again.

3. Add components to each line

There are four lines: Exhaust (Izpuh), Intake (Zajem), Return (Odvod) and Supply (Dovod).

• Add — hover a pipe and click one of the + markers. Type to search, then pick a component (or press Enter for the first match); it is placed exactly at that spot. The list shows the components that belong on that line, and the same component can be added more than once.
• Edit — click a component to open its options:
  • Signal — continuous or discrete (dampers, humidifier).
  • Readout — value boxes next to the icon (temperature, humidity, CO₂, pressure, flow, position, speed).
  • Setpoint — a setpoint box for the measured value.
  • Indicator — a ΔP switch or alarm icon on the component.
• Move — drag a component along its pipe.
• Remove — click the × that appears on hover, press Delete while it is selected, or use Remove in its options.

Use Element size in the bottom-right corner of the preview to make all components smaller or larger.

4. Export

Click Copy to atvise (top right). The finished display is copied to your clipboard — paste it into atvise as a new SVG display.

Tips

• If a component looks unbound or missing data after import, double-check the node path prefix, icon library and Modbus table in Settings.
• You can revisit and change anything — the preview and export always reflect your latest choices.
