PS2500/4500 Main Controller – BACnet/Modbus Protocol
Main Controller for A/C and Fan coil in Building
Management System (BMS) application, with BACnet or
Modbus protocol
The PS2500/4500 - Family consist of main controllers, with
BACnet or Modbus Protocol, for A/C and Fan Coil BMS
applications. It has a modular, user-friendly design with various
A/C or Fan Coil applications built-in, field selectable. This
modularity allows you to have one main controller for different
A/C or Fan Coil applications and suit it according to customer’s
needs on the spot.
The PS2500/4500 - Family also offers cost efficient capabilities,
such as, occupancy sensor, and smart algorithm for maximum
energy saving.
Each of the PS2500/4500- controllers is factory pre-programmed
to save valued time on field programming.
Please note the PS2500/4500 are also available as a
CTU2500/4500, with additional advanced features.
