Description of application and parametersApplication "RTC"Product manual 2CKA001473B9679 │14811.4.5 Summer compensationNoteThis parameter is only available if the "Device function" parameter is set oneither "Single device" or "Master device".11.4.6 Summer compensation — Summer compensationOptions: NoYesIn order to save energy, and to ensure that the temperature difference occurring during entryand exit of a climate-controlled building stays within comfortable limits, the excessive reductionof room temperature should be prevented during high temperatures in the summer ( Summercompensation according to DIN 1946). The room temperature is increased by adjusting thesetpoint temperature for cooling.Raising the room temperature does not, however, mean that you heat up the room. Rather, theadjustment is intended to allow the room temperature to increase to a certain setpoint withoutcooling. This, for example, prevents the air-conditioning system from further reducing the roomtemperature to 24°C with an external temperature of 35°C.However, activation of the summer compensation requires an outside temperature sensor thattransmits its measured value to the bus and can be evaluated by the room temperaturecontroller.The following parameters are available for summer compensation:■ "Lower outside temperature value for summer compensation",■ "Upper outside temperature value for summer compensation",■ “Lower setpoint offset for summer compensation",■ “Upper setpoint offset for summer compensation"Above the "Upper outside temperature value", the minimum setpoint temperature for cooling isthe outside temperature minus the "Upper setpoint offset". The outside temperature has noeffect on the minimum setpoint temperature for cooling below the "Lower outside temperaturevalue". Between the "Lower" and "Upper outside temperature value", the minimum setpointtemperature for cooling undergoes floating adjustment by the parameterized setpointtemperature equal to the outside temperature minus the "Lower offset" to a value equal to theoutside temperature minus the "Upper setpoint offset" as a function of the outside temperature.
