4.4 Functions

The room operator units with control functions can be integrated in a KNX network. The control functions for room temperature and ventilation allow for immediate control of suitable actuators to control heating, cooling, and ventilation.

4.4.1 Measuring

he room operator units measure the room temperature via an integrated sensing

dity

T element. The room temperature can be transmitted to other bus members and serves in KNX as control variable of the integrated room temperature controller. The outdoor temperature received via the KNX bus is only used for indication on the display and has no effect on the control.

he room operator units acquire the relative humidity in the room with the aid of a

T humidity sensing element integrated in the front module. The relative room humidity can be transmitted to other bus members and serves in KNX as control variable of the integrated ventilation controller.

The room operator units determine the CO

concentration via infrared absorption

measurement (NDIR). The sensor provides exact measurements at all times and does not require maintenance or recalibration thanks to an integrated, stable reference light source. The CO

concentration can be transmitted to other bus

members and serves in KNX as control variable of the integrated ventilation controller.

The background-lit symbol informs on the current level of CO2 in the room. The colors green / orange / red of the background lighting indicate good / moderte /

poor air quality. The display can be switched on or off by another bus member, e.g.

switch or timer.

ventilating, and air conditioning actuators via integrated control functions for room temperature, humidity, and air quality.

A proven PID controller for heating and cooling is provided to control the room temperature. The controller supplies a continuous or a pulse-width-modulated PID signal for one heating and one cooling actuator. The room temperature setpoints for the two operating modes heating and cooling as well as a blocking object can be set using the touchkeys and the display, or received from the bus. Changeover to the operating mode Heating/Cooling is automatic. Preset control parameters, adjusted for the heating type or cooling type, are available for selection.

concentration measurements are influenced by air pressure and temperature.

The lower the air pressure, the lower the measured value. Temperature influence is corrected automatically. The sensor allows for correcting the determined measured value to the prevailing average air pressure at the mounting location. To do this, altitude [m above sea level] must be set. The correction has the following effect on an uncorrected measured value of 1000 ppm at normal conditions (0 m altitude, 25 °C):

his application is recommended for smaller offices with a single heater.

T The room operator unit measures and regulates room temperature and sends the regulation signal to the valve drive actuator via KNX bus.

In addition, window contacts and presence detectors influence the control behavior of the room operator unit and increase the room‘s energy efficiency. For example, if

Page 23

no one is in the room or if the window is open, the radiator valve closes and reduces the room temperature automatically. Up to 4 window contacts and presence detectors can be connected via KNX bus.

4.5.2 Presence dependent room climate control with operation of all disciplines

Key (Example of a possible combination of components)

1. Room operator unit QMX3.P02

2. Room sensor QMX3.P70

3. Room operator unit QMX3.P37

4. Presence detector UP 258

5. Switch actuator N 562/11 for fan

6. Shutter/blind actuators N 523/04

7. Universal dimmer N 528/31 with sub-module N 528/41

8. Thermal drive actuator N 605 for up to 6 rooms

9. Thermal valve actuator STA23 (up to 4 per room)

his application is especially suitable for rooms with several heaters, e.g. in offices,

lecture halls or conference rooms.

The room operator unit (1) measures and controls the room temperature and sends the control signal to the thermal actuator (8) via KNX bus. Together with the integrated room temperature control, the sensor provides for a comfortable room climate.

The Room operator unit (2) measures the air quality (CO

) in the room, controls the

ventilation as required and thus saves energy and costs. The buttons on the room operator unit (1 and 3) can be used to control shading, lighting and scenes for example.

Additional room operator units (1) can also be connected, e.g. in large rooms with several doors.

The parameters Heating/cooling type adapt the controller to the heating type. In addition, the controller knows two control algorithms, one for modulating mode (0..100%) and one for PWM m ode (on/off). The parameter "Positioning signal type" selects the mode. The positioning signal type is the same for all operating m ode.

n modulating mode (Obj. 6, 7), for a modulating positioning signal ≠ 0, the applicable,

associated PWM output is "on".

Devices

Provides the room temperature value from the integrated sens or. Value of the outside temperature sensor: See object 53.

Must be placed in a group address to display the value on the display.

In the operating mode "Auto", the controller independently changes over between heating and cooling mode. But only either the cooling or heating mode is always active. If the object room temperature controller is enabled, the operating mode can changeover between "Off” (Obj. 3 = 0) and "Auto” (Obj. 3 = 1). The standard operating mode is "Auto”.

The operating m ode switches to "Auto" if the room temperature controller is enabled (1 = Controller on). The operating m ode switches to "Off" when s witching off (0 =

Controller off). The default value is controller on = 1.

The setpoints for cooling and heating mode do not lock out each other. In operating mode "Auto”, for cooling setpoint <

heating setpoint, the heating m ode is nevertheless active. The controller's comfort setpoints can be adjusted over the bus using these objects. As long as no other values are received by the bus or adjusted on the device with display, the received setpoints of objects 4 and 5 appl

y. Objects 4 and 5 act directly on the internal controller. The display on the device does not change! In other words, you can adjust the active cooling setpoint as desired using object 4 (without limiting by the heating setpoint) without this being visible on the display. The display for setpoint and operating m ode rem ain unchanged. Object 4 is once again overwritten if something is adjusted on the device (s etpoint and operating mode). In other words, you can influence the controller for short periods using both objects .

In PWM mode (Obj. 8, 9 as well as Obj. 6, 7), the cycle time and pulse length is adapted to the type of heating, the s etpoint, and the meas ured room temperature. The minim um cycle is 12 minutes; the minimum pulse length 4 minutes. The modulating positioning signal outputs values 0% or 100% in this operating mode.

The number and type of available objects as well as adjustable parameters can vary depending on basic configuration. For detailed documentation on KNX data point types, see [5].

Heating type* Radiator heating slow

Cooling type

Parameters heating / cooling type allow for adapting the controller to the type of heating / cooling. In addition, the controller features two control algorithms: one for continuous mode (0..100%) and one for PWM mode (On/Off). The mode is selected via parameter "Control value type". The control value type is identical for all operating modes. In continuous mode, the associated PWM output is "On" at continuous control value ≠ 0.

(Radiator heating fast) Floor heating slow

(Chilled ceiling)

X X X X X X X

In PWM mode, cycle time and pulse width are adapted to the type of heating / cooling, the setpoint, and the measured room temperature. The min. cycle time is 12 minutes, the min. pulse width is 4 minutes. The continuous control value issues 0% or 100% in this operating mode.

Commissioning with ACS

6.1 Engineering

Tool ACS790 is used for engineering with devices from the Synco 700 range. This tool is documented in Service- and Operating software ACS790 [6].

For ACS790, version 8.23 or higher must be installed.

During room operator unit mounting, the address labels can be peeled off the devices and stuck to a floor plan or similar to show the KNX IDs and the physical location in one place.

After mounting/installation, the devices are detected after updating the ACS790 device list. The devices can be easily identified in the device list based on the collected KNX IDs, and the physical addresses can be assigned as planned. As a result, commissioning requires only very little effort.

6.2 Commissioning

Depending on the environment, both type and number of adjustable parameters will vary. Prior to commissioning, all devices must be mounted as per the mounting instructions [2] and connected to bus cabling. If available, pushbuttons and external temperature sensors must also be connected to the device. Bus cabling must be tested.

All other indication types are irrelevant for KNX LTE-Mode.

1. Select a room operator unit from the device list via the KNX ID (KNX-IDs must be collected during mounting).

2. Double-click this line to open the "Address assignment" dialog.
