R&D, manufacturing and sales under one roof
Because we develop the hardware, firmware and programming tools ourselves, feedback from the field goes straight into the next firmware and product release.
What we do
From R&D to manufacturing, from sales to technical support and service.
Research and development
Our own team develops the hardware, firmware and programming tools of the Coselium controllers, remote I/O and software.
Manufacturing
We manufacture Coselium controllers and I/O modules and ship them with current firmware and documented factory settings.
Sales and partner dealer network
We supply Coselium products directly; for sales, technical support and service, please contact us. We are establishing our partner dealer network with building automation companies active in installation and commissioning.
Training and technical support
Training, application support, firmware updates, and service and returns (RMA) for our products.
