The building automation systems we program

Elyos programs, takes over and services building automation systems from Siemens (Synco and Desigo), Distech Controls, Priva, Honeywell Trend and KNX. [to confirm] We get them talking to each other and to your supervision system over BACnet, Modbus, KNX or M-Bus. New installation or existing one, in Brussels and across Belgium [to confirm]: send us your controller reference and we will tell you what we can do.

Distech Controls

Siemens, Distech Controls, Priva, Honeywell, Trend and KNX are trademarks of their respective owners.

Siemens Desigo

PX
PXC
Desigo Insight
Desigo CC

Where you find it: PX or PXC controllers in the control panels, and Desigo Insight or Desigo CC supervision on the operator workstation.
What we do on it: takeover of an existing installation, extensions, migration from PX controllers to the PXC generations, upgrade from Desigo Insight to Desigo CC, troubleshooting. [to confirm]

Siemens Synco

Synco 700
RMU
RMH
RMK

Where you find it: stand-alone controllers in the plant room or on air handling units, for example from the Synco 700 range, with an RMU, RMH or RMK reference on the label.
What we do on it: configuration and adjustment, takeover of a controller already in place, extension modules, connection to a supervision system, troubleshooting. [to confirm]

Priva

Compri HX
Blue ID

Where you find it: Priva Compri controllers, including the HX generation, or Blue ID on more recent installations.
Worth knowing: support for Priva HX hardware ends on 1 January 2027, and Priva offers a migration to Blue ID. If your building runs on Compri HX, now is the time to plan what comes next.Last checked: 9 November 2026, on priva.com
What we do on it: takeover and troubleshooting of Priva installations [to confirm], and planning the migration from Compri HX to Blue ID. [to confirm]

Honeywell Trend

Where you find it: Trend IQ controllers in the panels, from IQ3 units still in service to IQ4 and IQ5, with or without a supervisor workstation.
What we do on it: takeover of a site with no supervisor or backup, migration from IQ3 to IQ4 or IQ5, a BACnet gateway to your supervision system, troubleshooting. [to confirm]

Distech Controls

ECLYPSE
BACnet
IP

Where you find it: Distech Controls ECLYPSE controllers, on the IP network and communicating over BACnet.
What we do on it: programming, takeover of an existing installation, connection to your supervision system. [to confirm]

KNX

Where you find it: KNX push buttons, sensors and actuators that control lighting, blinds and temperature room by room in commercial buildings.
What we do on it: KNX integration in commercial buildings. KNX runs the rooms, the BMS runs the heating and cooling plant, and our job is the gateway between the two. We do not work on home automation. [to confirm]

BACnet, Modbus, M-Bus: getting your equipment to talk

In the same building, the boiler may speak Modbus, the air handling unit BACnet, the meters M-Bus and the lighting KNX. To see all of it on one supervision system, you need the right gateway, a BACnet to Modbus gateway for example, and a points mapping table checked point by point. That is what we do.

BACnet
The open protocol of building automation: BACnet/IP over the IT network, or BACnet MS/TP over a serial bus. Most supervision systems read it.
Modbus
A simple protocol found on many boilers, heat pumps, chillers and variable speed drives. Modbus RTU runs over an RS-485 bus, Modbus TCP over the network.
M-Bus
The bus for energy, heat and water meters. It provides the readings a BACS needs to monitor energy use.
KNX
The standard for room-by-room installations, linked to the BMS through a gateway.

Our job: choose the gateway, address the devices, draw up the points list and its mapping, then check every value on the supervision system. [to confirm]

System not listed?

Another brand, a controller whose name nobody remembers, a supervision system that no longer opens: send us a photo of the label and of the control panel. We will tell you whether we can take it over or connect it to the rest of the installation, or whether it is better replaced.

How we take over an existing system

Which controller do you have?

A photo of its label is enough to start: the brand and reference are printed on it.
