Control System 279
1. Brief Introduction about Controlling System
The control system adopts modular design, that is, all indoor units communicate with outdoor units, refer to the
following figures for the control structure between indoor units and outdoor units. In the structure, the indoor
control board receives the information from users (for exam. set temp., fan speed etc.) and environment (ex,
indoor coil temp., indoor temp. etc.) ,and organize it to control the action of relevant parts such as EXV,
four-way valve etc , then transmits the signals to outdoor control board through the following communication
circuit. Outdoor main control board can deal with the information from indoor unit and figure out the best
running mode, then transfer the instruction to the outdoor auxiliary units and indoor units to carry out it.
The four units combination control structure as following:
