In the past, HVAC management requires more human resources to maintain or registration sheet. Most of the effectiveness of the newspaper need deliberately SHEET all information and data chillers, Building Inside-outside temperature, the temperature of water inside and outside buildings. The reasons why we must keep track deliberately detailed, hourly, monthly or yearly analyzed to improve the registration form efficiency.In HVAC, history data is required to analyze and solve the problem.
You can see that management of the record sheet is required to save the human information deliberately, otherwise the information is inaccurate and too late to solve the problem quickly.
The idea of solving the difficulty of the HVAC system is to manage things centrally or calls a "Centralized Management".

They must learn and communicate with suppliers of HVAC system to verify whether each computer can connect devices to the console interface or not. (Where, the team could have an interface to retrieve information. The owners have to replace with the new model or to find the controller computer and the module input-output interface.)
Assignment of personnel responsible for particular system.
Estimates based on the structure, complexity and system size. (for the example protocol converters hardware RS232, RS485 communication) Microcontroller Module, Inverter, Computer.
