HVAC contractors, MEP consultants: we take the controls package
Elyos Building Automation, a controls integrator based in Anderlecht, Brussels, works as an HVAC subcontractor for the controls package: functional design, control panels, programming of the controllers and the building management system (BMS), and point-by-point commissioning. [to confirm] We work for HVAC contractors and MEP consultants across Brussels, Wallonia and Flanders [to confirm], from a specification and the system schematics.
For HVAC contractors
You are the HVAC contractor or the electrician on a project, with the heating, ventilation or air conditioning package. Hand the controls to us: you keep your package, we take what runs it, from fitting the control panels to commissioning with your team, on new builds and refurbishments alike. [to confirm]

At handover, who keeps the program?
Without a backup, the next contractor has to rebuild the program from what the installation does. So the rule is set in our quote [to confirm]:
- The program and its backups
- handed to the building owner at handover, with a copy for you. We keep a dated copy.
- Supervision software licences
- in the building owner’s name.
- Passwords and remote access
- handed to the person the owner names.
During the warranty period, your client comes to you: we step in when you ask us to. [to confirm]
For MEP consultants
As the MEP consultant, you write or check the controls section of the specification. We can help you upstream [to confirm]:
- the functional design: sequences, time schedules by zone, setpoints, alarms and metering;
- the points list for each item of plant, with the protocol of each link;
- a specification review: what is missing to price it, the brands specified, the interfaces with the other packages.
The systems we program
Siemens Synco and Desigo, Distech Controls, Priva, Honeywell Trend and KNX, linked over BACnet, Modbus or M-Bus. [to confirm] Does your specification name another system? Send us its reference and we will tell you whether we can take it on.
What we need to quote
A complete file gets an itemised price, with our assumptions in writing. [to confirm] Please attach to your email:
- the controls specification, or the HVAC specification if it covers the controls;
- the points list, if there is one;
- the hydraulic and air-side schematics;
- the drawings, showing the plant rooms;
- the system specified, if any, and any existing supervision to connect to;
- the planned split with the other packages;
- the tender deadline and the target commissioning date.
Without a specification or schematics, we cannot give a firm price. [to confirm]
Large files: a download link is fine. [to confirm]
Frequently asked questions
Can you work under our name?
Yes, if it is agreed in the quote: we work as your controls team, and the handover documents can carry your name. The building owner still receives the backups, the licences and the access codes. [to confirm]
Do you quote from a specification alone?
Yes, if it describes the functions required and comes with the schematics, ideally with the points list. If anything is missing, we tell you what before we price. On a refurbishment, a visit to the existing installation is often needed. [to confirm]
Do you commission on site with our team?
Yes, point by point, on site. To drive the valves, pumps and air handling units, we need your fitter there, a system that is filled, vented and powered up, and the other packages running. [to confirm]
Which documents do we receive at handover?
The as-built points list, the updated functional design, the control panel wiring diagrams, the commissioning record and a backup of the programs. Enough for your as-built and O&M files, and for anyone to take over the system. [to confirm]
A controls package to price?
Send us the specification and the schematics, and we will come back to you with a price or with a list of what is missing. [to confirm]
