High-end User Interfaces

The FCU-503 is fully compatible with the high end, attractive and user friendly RDU-Touch and CCS comfort control user interfaces.

Set up for you

All our FCU-503 controllers are supplied pre-programmed for your project requirements. Our aim is to take the on-site burden away from our customer by setting up the controllers prior to dispatch reducing on-site commissioning costs for our customers.

Flexible Control

As standard the FCU-503 controllers provide advanced FCU and UFH control solutions incorporating flexible fan control, fabric protection, set back, limit control, system flush / valve exercising and BACnet communications.

Two for one control

Do you need to control heating and cooling in a bedroom and heating only in a dressing room or en-suite? Control both completely independently from the FCU-503, reducing hardware requirements and utilising a single RDU-Touch or CCS user interface for both spaces.
