1.4 Structure and operation of the System
The System includes metal cabinet CSAHS (Figure 1, position 1) that powers AHU
(figure 1, position 2) with or w/o RF transparent dome (figure 1, position 3). Temperature
set up and control inside each AHU (dome) is carried out using repeater (figure 1,
position 4). Use КР to connect 2-20 AHUs to one CSAHS simultaneously (figure 1,
position 5).
