Board functions: descriptions Control Three types of control are possible. Refer to your order acknowledgement to see which type you have selected: choices • On/Off: Cascade control by activation of fan stages. • Speed control: Fan speed control. • Mixed: Speed control on stage 1, cascade control for the following stages.
The running time of each fan stage is balanced by a time counter. balancing Spray Used to increase the efficiency of the AeroConnect by spraying very fine droplets of water into the ambient air to cool it through evaporation. (units with spray...
Board functions: descriptions (continued) Free cooling During free cooling, the dry cooler is run with a CIAT chiller. Both units are controlled by the board. The three-way valve can be controlled by the board provided the maximum current is 3 A and the maximum voltage is 230 V. Refer to the chiller pump curve to size the valve.
Options Relay boards The boards must be installed in a cabinet. It has dry contacts for displaying three parameters: unit operation, sensor faults Main board and fan stage faults. Additional board For units with a motherboard and a daughterboard. It has dry contacts for displaying two parameters: sensor faults and fan stage faults.
