protects the critical components of the chiller by
responding to the external signals of its system sensors:
- motor temperatures
- refrigerant gas and oil pressures
- correct phase sequence band phase loss
Open Network Integration
Daikin has released a gateway for connection to BACnet,
LonWorks and Modbus networks equipment and building
control systems. BACnet, LonWorks and Modbus networks
are recognised worldwide as the de facto standard within
the building controls industry. BACnet, LonWorks and
Modbus data communication protocols make it possible to
control access, energy management, fire/life/safety, HVAC
and lighting etc.
Simultaneous operation of up to 5 chillers is optional through
EKCSCII sequencing panel (this function enables a Daikin
11MW chiller plant to be operated via a single controller).

- Air conditioning and the environment 2
- Air conditioning systems provide a significant level of indoor comfort making possible optimum working and living conditions in the most extreme climates in recent years motivated by a global awareness of the need to reduce the burdens on the environment some manufacturers including daikin have invested enormous efforts in limiting the negative effects associated with the production and the operation of air conditioners hence models with energy saving features and improved eco production techniques have seen the light of day making a significant contribution to limiting the impact on the environment 2
