ABB i-bus ® KNXParametersVC/S 4.x.1 | 2CDC508220D0211 Rev. A 1297.7.2 Operating mode after bus voltage recovery, ETS download and resetOptions: ComfortStandbyEconomyBuilding ProtectionThe parameter defines which operating mode is to apply after bus voltage recovery, ETS download andreset. The operating mode remains active until a new operating mode is set, e.g. via the Operating modegroup object.NoteThis operating mode should be defined during the planning phase. If the operating mode is definedincorrectly, there may be a loss of comfort or increased energy consumption.7.7.3 Comfort heating setpoint = Comfort cooling setpointThis parameter is enabled if the controller has been parameterized both for heating and for cooling.For this purpose, Deactivated must not be selected for the parameters Basic-stage heating andBasic-stage cooling in the Application parameters parameter window.Options: NoYesThis parameter defines how the comfort values for heating and cooling depend on each other.• no: Two separate comfort setpoints are used for heating and cooling. The related active setpoint isoutput via the Current setpoint object. The changeover between heating and cooling is undertakenusing the method defined in the Application parameters parameter window in the Heating/coolingchangeover parameter. On the selection of the Automatically option, the changeover between heatingand cooling is dependent on the absolute temperatures set for Comfort heating/cooling.• yes: The device has one and the same setpoint for heating and cooling in the Comfort mode.The changeover to heating takes place on dropping below the setpoint minus the hysteresis.The changeover to cooling takes place on exceeding the setpoint plus the hysteresis. The hysteresisis parameterizable. The Comfort heating setpoint and Comfort cooling setpoint parameters arereplaced by the Comfort heating and cooling setpoint parameter. In addition, the Hysteresis for Toggleheating/cooling parameter is displayed.
