>> Features of centralized control using power line communication

01 Using the power line for the FCU control communication cable

① When group-controlling fan coil units by room or individually controlling each unit from a central control
device, communication line work must usually be done for each product. However, there is no need for
separate communication line work as this product is already supplied with power, and the control system
carries signals over the power line without the need for additional communication line work.
② In installations with multiple products like an RS-485 communication system, there is no need to check
for misconnection of communication lines, poor contact of lines, disconnection of wiring, etc., and the
installation and commissioning time is shortened.

02 Minimization of Noise Impact

① Utilizes cutting-edge technology to minimize the impact of noise caused by electricity and radio waves.
② Noise effects are minimized, allowing smooth communication at high speeds.

03 Centralized control available in large-scale environments

① Even in environments with over 25,000 fan coil units installed, centralized control can be performed
smoothly and swiftly.
② Additional expansion and changes in office layouts can be easily accomplished by adding power line
communication modules and changing addresses.

04 Energy-saving benefits

① Allows for individual control of products based on government-recommended temperature settings
② Utilizes features such as scheduled operation and centralized control of room occupancy from the central
control room
