6.1. About the controller
The Kirloskar “PRODIGYTM SERIES” Scroll Chillers have a state of the art control system ‘K
– Smart’ which consists of main controller, the temperature and pressure transducers, expansion
boards, and a backlit LCD display. The K-Smart controller is a rugged microprocessor based
controller. It is designed to provide primary control, monitor the chiller, protect the chiller in
case of any unhealthy condition, interface with building management systems and communicate
both locally and remotely. The K-Smart controller provides flexibility with set points and control
options that can be selected prior to commissioning the chiller or when the unit is live and
functioning. Displays, alarms and other interfaces are accomplished in a clear and simple
graphics / language that inform the user as to the status of the unit. The K-Smart controller is
designed to safeguard the chiller, eliminate the need for manual intervention and to provide a
simple but meaningful man-machine-interface. The K-Smart controller provides the information
that would generally be available via gauges, temperature measuring devices, an amp probe, etc.
In addition to it, it also controls and gives commands to the various unit mounted devices such
as, solenoid valves, etc. to achieve optimum operation of the chiller. The controller also displays
information on alarms, lockouts and various control states.
6.2. PCOOEM+ Board Carel Controller
The pCOOEM+ (medium) is a microprocessor-based, programmable electronic controller that is
fully compatible (hardware and software) with the pCO Sistema family of devices, which
includes programmable controllers, user terminals, gateways, communication devices and remote
management devices. These devices represent a powerful control system that can be easily
interfaced with most Building Management Systems (BMS) available on the market. The
controller is fitted with a 32-bit microprocessor and has up to 4 Mbytes of memory to ensure
high performance in terms of speed and memory space for running the control program. The
program and parameters are saved permanently in a non-volatile memory (fl ash memory),
preventing data loss in case of power failures (without requiring a backup battery);
