AdiaPure
User documentation for the AdiaPure humidifier controller and its screen.
AdiaPure is the controller for a demand-controlled hybrid adiabatic humidifier. It reads a humidity demand, drives the water pump and the atomisation-stage valves, watches the water quality and the hydraulics, and reports everything on a built-in screen, over the network and on the fieldbus.
This documentation covers:
- Hardware revision: v0.3
- Firmware: the version currently built in
Software/(the AdiaPure application firmware and the screen firmware)
What the product does
The controller sits between your building's control system and the humidifier. It:
- takes a demand — a percentage from 0 to 100 — from an analogue input, a digital on/off input, a fieldbus register, or a return-air humidity transmitter;
- turns that demand into water: it starts the pump and opens the atomisation valves for as long as the demand requires, pulsing them between a low and a high opening level;
- limits the output when the air leaving the humidifier is already too humid, so that condensation inside the unit is avoided;
- flushes the valves on a timer and whenever the water quality drifts out of range;
- raises alarms for water quality, pressure, temperature, leaks and pump faults;
- keeps a history of measurements and alarms in its own non-volatile memory.
The three user interfaces
| Interface | Where it lives | Who uses it |
|---|---|---|
| Screen | A touch panel on the humidifier, connected to the controller board by a single cable | Operators, day to day |
| Web interface | Served by the controller on the local network, port 80 | Installers and administrators |
| Fieldbus and USB | Modbus RTU/TCP, BACnet/IP, BACnet MS/TP, USB | Building management systems and service technicians |
The screen and the web interface show the same values and can change the same settings. See Connectivity for how to reach each one.

Conventions used in this documentation
- Board terminals are identified by their reference designator, for example
J12. The board carries no printed labels, so this documentation is the only place where the terminal map exists. The functional name used in the schematic is given in brackets, for exampleJ12(MEn). - Screen labels and web interface labels are written in
backticksexactly as they appear, so you can match them against what you see. - Values that the product measures carry the unit, for example
24.0 °Cor0.5 bar. - A percentage is written
0–100 %when it is a demand or an opening level.
