You supply the hall. We supply the control.
AERDOMA does not compete with the hall manufacturer. It is the control and operations part of the delivery, and it can be connected to a new hall as well as to an existing one — whoever built it.
The hall manufacturer supplies
- the envelope and structure
- fans and air handling
- the heating unit
- civil works
- anchoring and structural design
AERDOMA supplies
- the electrical switchboard
- sensors and metering
- the local control unit
- safety and operating logic
- lighting
- the access system
- bookings
- the cloud application
- energy and operating economics
- reports
- optional camera integration and AI analysis
The scope of supply is set after a technical assessment of the specific hall. We do not compete with the hall manufacturer — we complement them.
Split of scope
So that nobody loses track of who is responsible for what.
| Part | Hall manufacturer | AERDOMA |
|---|---|---|
| Envelope, structure, anchoring | yes | no |
| Fans and air handling unit | yes | no |
| Heating unit | yes | no |
| Electrical switchboard and controller | no | yes |
| Sensors, metering and safety interlocks | no | yes |
| Lighting and access system | no | yes |
| Bookings, cloud and mobile application | no | yes |
| Cameras and optional AI analysis | no | by configuration |
The boundary is physical: we end at the switchboard terminals and at the communication interface. Whatever lies beyond them in the technology stays yours.
What we need from the hall manufacturer
- Hall type and dimensions, number of sectors and number of air handling units.
- Data sheet of the air handling unit including fan power and drive type.
- Type and output of the heating unit and how it is switched or modulated.
- Operating and emergency envelope pressure, and the pressure/wind curve if the manufacturer prescribes one.
- Location of the plant room, doors and anchor points, and the cable routes.
- Prescribed safety devices and how they are required to be wired.
What we need from the electrical and HVAC engineer
- Available power, connection type and protection arrangement.
- Whether there is or will be a standby source on site, and in what mode it should start.
- The required interface to a supervisory system, if one is called for — Modbus TCP or BACnet IP.
- The required archiving scope and the intervals for each quantity.
- How the site connects to the network and whether a dedicated public IP address will be available.
- Lighting requirements: number of circuits, sector split and luminaire type.
I/O and communication points
We supply the input and output schedule written out with named points, not as an estimate. A sample wiring diagram and the I/O overview are in the technical documents.
-
Measured continuously
Temperature, pressure, flow velocity and humidity in both supply and extract, CO and CO₂, envelope pressure through an operating and an emergency sensor, temperature and humidity in the hall, and a weather station outside.
-
Status inputs
Airflow pressure switch, FAN and LIMIT thermostats, flue pressure switch, damper positions, breaker and phase-monitoring relay status, motor thermal contact, switchboard and plant room door contacts.
-
Outputs
Drive control, damper actuators, switching of lighting sectors through contactors, the door lock pulse, and the generator start command.
-
Communication
Modbus TCP and BACnet IP to expose the measured and control parameters to a supervisory system. The drive is read over Modbus. If the air handling has its own control panel with Modbus TCP, the controller connects to it and writes only what the operator is allowed to.
Switchboard, controller and safety interlocks
The switchboard is our own product — we design it, build it and commission it. That is the original business of AJservices and we have been doing it longer than software.
-
Safety is not in software
Safety thermostat with manual reset, motor and surge protection, pressure relief damper, actuator return springs and the fire damper work even when the controller is down.
-
The override rule
The lower layer always overrides the higher one. The server can never permit something the controller has blocked, and the controller can never bypass the hardware branch. This rule does not change during a project.
-
Energy metering
An MID-certified electricity meter as the basis for recharging a sub-tenant. Heat or gas metering according to how the source is built.
-
Lighting and access
Lighting switched per sector with contactor feedback. A reader at the door and a lock with a three-second pulse. No dimming — luminaires in these halls have no intensity control.
Cameras
A camera system can be connected whether it is existing or new. Cameras are assigned to a specific hall or sector and their events can be linked to alarms.
AI evaluation is an optional layer. It is designed and approved separately for every installation, according to what the client actually needs.
Commissioning and service
- Taking over the documents and assessing the hall technically.
- Proposing the I/O scope and wiring diagram and agreeing them with the engineer.
- Building the switchboard and programming the controller.
- Installation, sensor wiring and commissioning on site.
- Testing the safety branches including an outage simulation and a generator test.
- Training the operators and handing over the documentation.
- Remote service access with a record of every intervention.
The hall manufacturer in the application
The hall manufacturer fills in a profile in the application — logo, service line, contact person, e-mail and website. The hall owner and manager see it with alarms and in the hall administration, so that they know whom to call when something fails. Players do not.
The manufacturer has its own role in the hall and sees only the halls it built or that have been entrusted to it.
Documents for public tenders
Without technical documents you do not get into a tender. The data sheet, the I/O overview, a sample wiring diagram and sample tender wording are ready to be taken over.
We write the sample wording to describe function and interface, not our own type plate. A specification that rules out competition tends to be challengeable.
Send us the hall documents
From the hall data sheet and the available power supply we can state the scope of delivery and what still needs to be resolved on site.
