Mitsubishi VRF systems control mechanisms can be grouped in 2 main categories: individual and centralized. These control mechanisms are divided into many models with different functions for users' requirements and needs.
Individual Control Elements include wired and wireless control elements. Operation, service and maintenance technical information can be entered over a wide LCD screen. There is a wide range of models with different functions addressing various needs, including models with minimum functions such as ON/OFF, mode changes, and fan speed, or with the function of start-up at different times a day via weekly programming, or with the function preventing over heating or cooling by determining lower and upper limits with adjustable temperature control.
Centralized Control Elements consist of interface elements that ensure the integration of the different functions with the centralized controller models and building automation systems. Thanks to these elements, control from a single control point for each indoor unit connected to the system is possible. Depending on the centralized control model used, many functions including ON/OFF, temperature and fan speed settings, weekly schedule, individual control elements restrictions, electricity-power computing can be utilized.
Without any software, operating and fault information related to the system is displayed on a PC via Internet and is stored using Web interface. In addition, access levels can be determined for data safety by IP filtering feature. Control systems can easily be turned into a part of a more comprehensive automation group by adaption to data based automation systems such as LonWorks and BACnet. Displaying error codes in all individual and centralized control elements also provides great convenience in maintenance and service interventions.
