This is where Syscom were called upon to complete major floor and plant refurbishments. The project spanned across 15 floors of terminal units with each floor containing its own AHU plant consisting of two to four AHU’s. The BMS controllers were upgraded from the old Siemens AS1000/ASI to PXC/RXC controls and integrated into the existing Desigo system. The required outcome was for the occupied building to be able to maintain comfort conditions for all occupants and meet critical control conditions within the property.
