995 Centralised control systems Integrated logics for Plant Management Control strategies Advanced control strategies can be chosen to optimise units life time and the energy efficiency of a chillers plant: J by sequencing it is decided which unit must start or stop J by staging the unit shares the load based on a threshold specified by the user Control options iCM can manage: J Up to 16 units Heating/Cooling mode, with iCM expanded kit J Up to 8 units Heating/Cooling mode J Special control options such as: VPF, Demand Limit, Rapid Restart are managed by iCM in a multiple unit system J Heat recovery option management J Free cooling option management J Manifolded pumps management (evaporator/condenser) – iPM control panel is required J Cooling tower system management – iCT control panel is required J Secondary circuits management - iSM control panel is required What are the main differences between Master/Slave and iCM? For Daikin unit equipped with MT4, iCM are set of functions embedded directly in the unit controller. In addition for those applications not covered by the embedded functions, iCM customized are also available. While Master/Slave can manage systems composed by units model of the same type, iCM can manage cooling, heating and plants made of different kind of units Feature Master/Slave New iCM Number of chillers UP TO 2 UP TO 16 Plants with All Chillers same models YES Plants with all Heat Pumps same models YES Plants with Multipurpose YES YES Mix of Chillers (max 2 circuits) + Multipurpose NO YES Mix of Chillers + Heat Pumps NO YES Chillers with Heat Recovery NO YES Chillers with free cooling NO YES Units with modulable capacity control YES YES Units with step capacity control YES YES Key Benefits J High performance J Lower energy & Maintenance Costs J Increase reliability & lifetime J Remote control and monitoring through Daikin on Site J No additional installation required
