CONTROL SYSTEM 11. 11.1 CONTROL SYSTEM General Functions and Operating Rules The DCI software is fully parametric. All the model dependent parameters are shown in Blue color and with Italic style [parameter]. The parameters values are given in the last section of this control logic chapter of the service manual. 11.1.1 System Operation Concept The control function is divided between indoor and outdoor unit controllers.
