Honeywell's Excel 10 Fan Coil Unit Controllers provide application flexibility for two pipe, four pipe or staged heat/cool fan coil unit applications � without the costs or headaches of complex wiring. All four of the Excel 10 Fan Coil Unit Controllers allow line voltage power to be direct wired to the controller transformer and fan speed relays. Reliable temperature and fan speed control, combined with the ease of integrating the Excel 10 Zone Manager into the EXCEL 5000®  System, give building managers the comfort and energy savings they expect from their DDC control system.

The open system advantage

The Honeywell Fan Coil Unit Controller uses the Echelon® LonMark® Fan Coil Unit functional profile for openness and interoperability with third party LonMark devices, giving you freedom of choice in system design.

 

Smart sequencing options conserve
energy and reduce equipment run time

  • Set point reset for electrical demand limit control
  • Energy-saving heating and cooling setpoints for occupied, unoccupied and standby modes
  • Automatic or manual control of fan speed sequencing
  • Configurable fan run times for minimum on, minimum off, run-up and overrun
