Wellset solutions: building automation hardware

EC conversion, heating plant control, I/O modules and SAIA PCD controller retrofit: open, documented products with no captive licence.

Wellset, Workswell’s product brand

Wellset distributes building automation hardware stocked and shipped from Switzerland, including products developed by Workswell, for electrical installers, integrators and technical consultancies. Products designed for concrete renovation problems, documented and based on open protocols.

Three product families

  • EC conversion: EC-SWAP converts a two-speed asynchronous ventilation motor to EC while keeping the existing control, without reprogramming the controller. The EC-SWAP-PRO, announced for 2027, adds control by an air quality sensor.
  • Smart & controllers: WS-SMART-HG for heating plant control (6 heating circuits, 2 DHW cylinders, BACnet / Modbus), WS-SMART-IO as a remote input/output module for air handling units (Modbus RTU), and the WS-HG switchboard with built-in control.
  • PCD & controllers: WS-PCD for the retrofit of SAIA PCD1 and PCD2 controllers, taking over the existing connectors directly.

How to order

The catalogue, datasheets and quote requests are on wellset.ch: business account with a UID number, net quote within 24 business hours. The availability and compliance status of each item are kept up to date there.

A building to measure, a consumption to understand?

A first conversation is usually enough to gauge the savings potential and the data available.
