The TROX PWX fancoils are supplied with specially-designed on-board controls packages, as standard. Two different STD controls packages are offered:

  • BACnet control, offering the full flexibility of uniquely addressed terminal units, which interface with Building Management Systems (BMS) and provide feedback on each unit’s performance
  • TROX can also offer standalone controls that allow user control of individual units where no BMS is present.

To complement these control packages, TROX is also able to offer a full water-side control package which has been designed to work seamlessly with either control option.


TROX UK has in-house test laboratories where all the PWX design solutions can be verified by the project team.
