  • Page 58: Limiting Values

    Software "KNX CO2 sensor" Functional description 4.2.4.3.4 Limiting values Four limiting values can be assigned to the CO measured value and two limiting values to the humidity measured value. This makes it possible to trigger actions when the adjustable limits are exceeded or undershot.
  • Page 59 Software "KNX CO2 sensor" Functional description Figure 13: Frequency of switching without hysteresis One can see here that when no hysteresis is incorporated the limiting value object changes its state each time the value is undershot or exceeded. This is different if you parameterise a change of state from '1' to '0' only when the limit value is undershot by the measured value minus hysteresis.
  • Page 60 Software "KNX CO2 sensor" Functional description i The hysteresis must be selected in such a way that the start of the measurement range is not reached or undershot and the end value is not reached or exceeded, as otherwise a change of state can only occur once and not any more until a reinitialisation.

    Software "KNX CO2 sensor" Functional description 4.2.4.4 Room temperature controller The device can be used for single-room temperature control.

  • Page 67: Control Algorithms And Calculation Of Command Values

    Software "KNX CO2 sensor" Functional description 4.2.4.4.2 Control algorithms and calculation of command values Introduction To facilitate convenient temperature control in living or business spaces a specific control algorithm which controls the installed heating or cooling systems is required. Taking account of the preset temperature setpoints and the actual room temperature, the controller thus determines command values which trigger the heating or the cooling system.
  • Page 68 Software "KNX CO2 sensor" Functional description It is possible to configure "Heating", "Cooling" or alternatively the mixed mode "Heating and Cooling" as the operating mode. Using the additional stages is also possible. In this connection, you can set different control algorithms for the heating and/or cooling system. Thus, you can use up to four separate algorithms for two-stage heating or cooling operation.

  • Page 71 Software "KNX CO2 sensor" Functional description the command values change, if required, only at these times. The disadvantage of a continuously varying temperature as a result of this feedback control option is in contrast with the advantage of this very simple 2-point room temperature control. For this reason, quick- reaction heating or cooling systems should not be triggered by a 2-point feedback control system, for this can lead to very high overshooting of the temperature, thus resulting in loss of comfort.
  • Page 72 Software "KNX CO2 sensor" Functional description Figure 21: 2-point feedback control for the single "Cooling" operating mode An additional 2-point feedback control heating or cooling level works exactly the same as the 2-point feedback control of the basic level. The difference is that the setpoint and the hysteresis values will shift by taking into account the configured level offset.

  • Page 75: Adapting The Control Algorithms

    Software "KNX CO2 sensor" Functional description 4.2.4.4.3 Adapting the control algorithms Adapting the PI control There are several systems available, which may heat or cool a room. One option is to uniformly heat or cool the surroundings via heat transfer media (preferably water or oil) in connection with room air convection.
  • Page 76 Software "KNX CO2 sensor" Functional description If the "Type of heating" or "Type of cooling" parameters are set to "Via control parameters" it will be possible to adjust the control parameter manually. The feedback control may be considerably influenced by presetting the proportional range for heating or for cooling (P component) and the reset time for heating or for cooling (I component).
  • Page 77 Software "KNX CO2 sensor" Functional description Adapting the 2-point feedback control 2-point feedback control represents a very simple temperature control. For this type of feedback control, two hysteresis temperature values are set. The upper and lower temperature hysteresis limits can be adjusted via parameters. It has to be considered that… A small hysteresis will lead to small temperature variations but to a higher bus load.

  • Page 99: Room Temperature Measurement

    Software "KNX CO2 sensor" Functional description 4.2.4.4.6 Room temperature measurement Basic principles The room temperature regulator periodically measures the actual temperature of the room and compares it with the given setpoint temperature of the active operating mode. The control algorithm calculates the adjusted command value from the difference between actual and setpoint temperatures.
  • Page 100 Software "KNX CO2 sensor" Functional description "received temperature value" The actual temperature is determined solely via a temperature value received from the bus. In this case, the sensor must either be a KNX room thermostat coupled via the 2-byte object "Received temperature" or a controller extension with temperature detection. The room temperature controller can request the current temperature value cyclically.
  • Page 101 Software "KNX CO2 sensor" Functional description i During room temperature control, the controller always uses the adjusted temperature value to calculate the command values. The adjusted temperature value is transmitted to the bus via the "Actual temperature" object (see "Transmission of the actual temperature"). When determining the measured value using combined sensors, the two adjusted values are used to calculate the actual value.

    Software "KNX CO2 sensor" Functional description 4.2.4.4.7 Command value and status output Command value objects The format of the command value objects are determined depending on the control algorithm selected for heating and / or cooling and, if applicable, also for the additional levels. 1 bit or 1 byte command value objects can be created in the ETS.

Continuous PI control: In case of a continuous PI control, the room temperature controller calculates a new command value periodically every 30 seconds and outputs it to the bus via a 1-byte value object.

A choice of data formats is available for this. The "Controller status" parameter in the "Room temperature control -> Controller general -> Command value and status output" parameter branch will enable the status signal and set the status format...
  • Page 105 Software "KNX CO2 sensor" Functional description "Controller general": The general controller status collects essential status information of the controller in two 1-byte communication objects. The "Controller status" object contains fundamental status information (see Table 8). The "Status signal addition" object collects in a bit-orientated manner further information that is not available via the "Controller status"...
  • Page 106 Software "KNX CO2 sensor" Functional description "Transmit individual state" The 1 bit status object "Controller status, ..." contains the status information selected by the "Single status" parameter. Meaning of the status signals: "Comfort mode active" -> Active if operating mode "Comfort " or a comfort extension "" is activated.
  • Page 107 Software "KNX CO2 sensor" Functional description With a permanently active command value limit, the initialisation behaviour cannot be configured separately after a device reset, as the limit is always active. In this case it is also not possible to configure any object. As soon as the command value limit is active, calculated command values are limited according to the limiting values from the ETS.
  • Page 108 Software "KNX CO2 sensor" Functional description Special case for command value 100% (Clipping mode) If with a PI control the calculated command value of the controller exceeds the physical limits of the actuator, in other words if the calculated command value is greater than 100%, then the command value is set to the maximum value (100%) and thus limited.
