1.6 Target audience, prerequisites This document assumes that users of the RXB Konnex controllers are familiar with the tools ETS Professional and/or Synco ACS and able to use them. It also presupposes that these users are aware of the specific conditions associated with EIB/KNX. In most countries, specific EIB/KNX know-how is transmitted through training centers certified by the EIBA (see www.eiba.com/ or www.konnex.org/). For details concerning the Konnex bus see document CE1N3127.
1.7 Bus supply for RXB controllers RXB controllers can work without bus supply if the following conditions are adhered to: • • • • • Parameterize only using the HandyTool (not with ETS or ACS). No integration in a building automation and control system (e.g. Desigo, Synco). No changeover mode (sensor signal via bus). No outdoor temperature via bus No master/slave combinations. Otherwise, the Konnex bus, used by the RXB room controller for communication, requires a bus supply.
1.8.2 LTE mode LTE mode was specifically designed to simplify engineering. Unlike with S-mode, there is no need to create the individual connections (group addresses) in the tool. The devices autonomously establish connections. Definitions In order to make this possible, the following circumstances are predefined: • Every device or sub-device is located within a zone • Every data point (input or output) is assigned to a zone • Every data point (input or output) has a precisely defined "name".
2 Definitions / Tools 2.1 Signals and parameters (presentation) The inputs, outputs and parameters of an application can be influenced in various ways. These are identified by the following symbols in this description of functions: Room unit Parameters identified by this symbol are influenced by the room unit. ETS Professional Parameters identified by this symbol are set using ETS Professional (EIB tool software). STOP The RXB2... KNX controller parameters can be set with ETS3 and later. The RXB39.
Note LTE-mode communication objects A list of all S mode communication objects is located in section 13.5; a detailed description of the Konnex data types in section 13.9.
2.2 Supported tools The RXB Konnex controllers can be commissioned with the following tools: • ETS Professional (ETS3 and later supports RXB2... ; ETS4 and later supports RXB39.1) • Synco ACS (V 5.10 and later supports RXB2... ; V8.22 and later supports RXB39.1). • HandyTool l (QAX34.3). STOP Note! • Be careful when using different tools. The following rule applies: Last one's right! • If you use OCI700 as an interface, it is connected to the service plug of the controller or of the room unit.
2.4 ACS Parameter setting in ACS This manual does not describe how the physical address is defined. This information can be found in the ACS description.
2.5 HandyTool Parameter setting using the HandyTool Tthe QAX34.3 room unit contains the function "HandyTool" allowing you to parameterize the RXB room controllers (from version 2.36). The following settings are possible in the room controllers: • Parameter • Physical address • Zones Group addresses (bindings) cannot be assigned. This must be carried out in ETS. QAX34.3 mmroom unit In addition to its room unit functionality, this device also allows for parameterizing the room controllers.

3 Select communication mode As stated in section 1, the RXB Konnex room controllers operate either in S-mode or LTE mode. They are used in S-mode when networked with the Desigo building automation and control system, and in LTE mode with the Synco system. Note ETS Professional The factory setting of all controllers and the basic setting of the tools is 0 = S-Mode. This minimizes the bus load. Exception: ACS changes the setting immediately to 1 = LTE + S. The ETS Professional is used in Desigo networks.
3.1 Zone addressing in LTE mode (in conjunction with Synco) This section applies only to LTE mode. In cases where RXB Konnex controllers are used in LTE mode (e.g. in conjunction with Synco) zone addresses need to be allocated. These must be defined together with the Synco devices at the planning stage. The zones to be defined are as follows: Geographical zone (Apartment . Room Subzone) Apartment = ---, 1...126 Room = ---, 0...63 Subzone =---, 0...15 Timeswitch zone (Apartment .
Outside air temperature zone Zone The outside air temperature (all Synco devices of series 700) is exchanged in this zone. = ---, 1...31 Master/slave zone (Apartment . Room Subzone) Apartment = ---, 1...126 Room = ---, 0...63 Subzone =---, 0...15 In cases where RXB controllers are to be operated in master/slave mode, a master/slave zone must also be defined. For the master, it is usual to enter the "geographical" zone of the master. The same master/slave zone is used for the slave as for the master.
ACS Professional Reducing the bus load HandyTool The zones are defined under Communication. Individual zones can also be disabled via "Command" if they are not being used. This has the advantage of reducing the load on the bus.
3.2 Geographical zone and time switch zone application example RXB with RMB795 To explain the philosophy of the room group, we use the following example. We assume to have a building with 3 floors accommodating a number of companies.
Sport Ltd uses 2 room groups For implementation of the application example, we focus on the floor plan of Sport Ltd.
Settings on the central control unit On the RMB795 central control unit, only the room group, that is, the "Geographical zone (apartment)" can be set. The room and the subzone use a fixed assignment (Room = 1, Subzone = 1). This means that for setting a room group on the central control unit, following applies: Room group = geographical zone (apartment.1.1).
3.3 Procedure for engineering Using the "C3127_Planning and Commissioning Report, Communication Synco 700", the plant and the required communication settings can be represented in an easy-tounderstand way. Proceed as follows: 1. 2. 3. Example Sport Ltd Enter general information, such as plant name, device names, device types, applications, etc. Transfer the device addresses of all bus users and the basic settings of communication from the floor plan.

4 Applications, parameters 4.1 Application selection Most of the RXB Konnex controllers store a number of software applications (e.g. RXB22.1/FC-12 with FNC03 and FNC05). The tool is used to select the required application. ETS Professional and ACS differ greatly in this regard. ETS Professional The tool displays all applications as "devices". The required application is defined by adding a "device".

5 Room operating modes 5.1 Description The room operating modes available with Desigo RXB are Comfort, Precomfort, Economy and Protection. In addition, there is a frost protection limit, at which, for example, an alarm can be triggered. Each room operating mode has separately adjustable heating and cooling setpoints.

Principle: "Occupied" takes precedence over “Unoccupied“.
Presence detector The presence detector is connected directly to a digital input on the room controller (see page 142); alternatively an EIB/KNX presence detector connected to the EIB/KNX bus may be used (see diagram below). The two inputs are OR-linked: If one signals presence, presence applies.

5.4.8 Third-party (S-mode) examples The following examples show two typical applications of time schedulers in conjunction with local control of the room operating mode. Example 1 Rooms with neither a room unit nor a presence detector The room operating mode in rooms 1…3 of a building is determined by the Room operating mode time schedule. Window contacts are installed in all the rooms. The following conditions are specified: • Overall, the building is in use from 06.00 to 20.00.
• The occupant(s) of Room 1 are working overtime. At 18.00 hours the room operating mode changes to Economy, even if the room unit is set to Auto (1). Comfort mode can now be re-activated with the Auto switch on the room unit (2). Comfort remains active for the pre-defined Temporary Comfort mode period (see page 143). In Protection mode however, the Temporary Comfort period is also overridden and the room operating mode changes to Protection (3).
5.5 Determine the room operating mode with Synco (LTE mode) In LTE-mode the effective room operating mode of the room controller depends on the central Room operating mode time schedule and/or on local influences such as window contacts, presence detectors or room units. The diagram below shows how these influences are processed by the room controller, and their priority: Central (ACS) Central (Synco controller) Local Controller Window contact DI Prio 0. 1. 1.

5.5.6 LTE-Mode Examples The following examples show two typical applications of the time schedule in conjunction with local control of the room operating mode. Example 1 Rooms with neither a room unit nor a presence detector The room operating mode in Rooms 1...3 of a building is determined by the Room operating mode time schedule. Window contacts are fitted in all rooms. The following conditions are specified: • Overall, the building is in use from 06.00 to 20.00.
• The occupant(s) of Room 1 are working overtime. At 18.00 hours the room operating mode changes to Economy, even if the room unit is set to Auto (1). Comfort mode can now be re-activated with the Auto switch on the room unit (2). Comfort remains active for the pre-defined Temporary Comfort mode period (see page 143). In Protection mode however, the Temporary Comfort period is also overridden and the room operating mode changes to Protection (3).
5.6 Determine the room operating mode without a bus (stand-alone) If no bus is connected, the effective room operating mode of the room controller depends on local influences such as window contacts, presence detectors or room units. The diagram below shows how these influences are processed by the room controller, and their priority: Local Controller Window contact DI Prio 1. Presence detector DI 3. PPS2 3.

Internal correction by controller The room controller corrects the setpoints as follows following a local shift: • Precomfort:: – The values are shifted in parallel to the Comfort values B . – The cooling setpoint cannot be lowered following central shift C . – The heating setpoint cannot be increased following central shift C .
7 Temperature measurement 7.1 Room temperature measurement Sources The value valid for temperature control can originate in various sources: – A room unit via PPS2 7.1.1 – An analog sensor via analog input B1 7.1.2 – Mean value of several sensors 7.1.3 – The bus. 7.1.
The sensors connected to terminal B1 can be tasked with different functions: Parameter setting Room Return air No sensor Only measured value acquisition Supply air (cascade) (RXB2... only) Note ETS Professional Description Room indoor air sensor (can also be used for averaging, see below).

Directly connected valve actuators Different applications support different valve actuators, and these do not all require the same number of outputs on the controller. – Thermal actuators are driven with an AC 24 V PDM signal – Motorized actuators are driven with an AC 24 V 3-position signal. – Electromechanical actuators (motors with spring return) have a special PDM algorithm that ensures that 50 position changes per day are not exceeded. This causes a slower control behavior.
Thermal valve actuators • It is not possible to ensure exact parallel running of more than one thermal valve actuator. If several fan-coils are controlled by the same room controller, preference should be given to motorized actuators. If thermal actuators must nevertheless be controlled in parallel, third-party thermal must be parameterized regardless of manufacture. This applies also if an external power amplifier is used to drive the actuators. • Thermal actuators operate at a raised temperature.

8.6 Room supply air cascade control (FNC08) Room supply air cascade control makes it possible to reach the required room temperature very quickly. On the basis of the measured room temperature, the controller calculates a setpoint for the temperature at the air outlet of the fan coil. A limit value can be applied to this temperature to prevent the introduction of uncomfortably cold / warm air into the room.

9 Fan control 9.1 Description 1 / 2 / 3-speed fan (RXB2...) All fan coil applications incorporate single-speed, two-speed or three-speed automatic fan control. The fan speeds are enabled and disabled via volt-free relay contacts. The controllers operate with an algorithm optimized for thermal or motorized valve actuators for each fan speed. Room unit Certain room units allow the user to select the fan speeds MANUALLY (in Comfort mode only).
The fan runs at fan speed 1 for as long as the heating/cooling valve remains partly open, or in the case of an electric heater, while the heater is in operation. • It is enabled as soon as the controller specifies a valve position or an electric heating output greater than 0. • It is disabled when the controller specifies a valve position or electric heating output equal to 0 and the minimum fan switch-on time has elapsed.

9.3 Description DC 0...10 V fan (RXB39.1) The fan coil applications with RXB39.1 incorporate continuous automatic fan control (DC 0…10 V). In addition the fan can be enabled and disabled via a volt-free relay contact. Controller RXB39.1 Controller outputs (fan) Output characteristic Outputs G0 / YC3 Q33 / Q34 DC 0…10 V signal for the fan Enable relay for the fan The output characteristic of the fan signal (0…10V) is defined via parameters P150 and P151. Output signal YC3 10 V E.g. 1: Pos.
Function The fan speed is controlled by a PI controller depending on the control deviation of the valve or reheater. The fan starts running at the min speed when the valve or reheater demand exceeds 4%; it is deactivated when the demand is 0% (hysteresis). Control strategy fan in sequence Control strategy fan in parallel When the valve or/and electric reheater is fully open AND the room temperature exceeds the fan offset (P162, P163), the fan output signal grows up to the max. value (P152, P154).

This running is activated by means of the sensor selection (return air sensor). The fan running time and period can be defined, see "Periodic fan kick", section 9.7.
9.3.3 Room unit (RXB39.1/FC-13 only) Certain room units allow the user to toggle the room operating mode and automatic fan operation or manual selection of the fan steps (in Comfort mode only). The reaction of the controller upon the user's inputs can be parameterized in the applications of FC-13.
9.3.4 CO Values representing fan speed Besides operation via a PPS2 room unit, he fan can also be operated via the KNX bus. In S-mode, control is shared between two communication objects: – Fan command value – Enable fan command value (activates input Fan command value). When Enable fan command value is disabled, the controller controls the fan automatically, and the Fan command value input is disabled.
The following example illustrates the effect of the commanded fan value via KNX bus on the room units's display: Command (from KNX bus) X = 0% QAX LED / cursor position Heating: I 0% < X <=23% Cooling: 0% < X <=33.5% Heating: II 23% < X <=50% Cooling: 33.

9.7 Return air sensor Periodic fan kick If the room temperature is measured with a return air sensor in the fan coil (connected to input B1, see Section 7), the fan must be switched on to ensure that the effective room temperature is measured correctly. The function "Periodic fan kick" is used for this purpose. From version V2.36, a reduced functionality (without time values for Comfort and Economy) is available even if no return air sensor is parameterized.
10 Master/slave 10.1 Description Example of a master/slave configuration: Several controllers are installed in an openplan office. One controller (the master) measures the room temperature and controls the other controllers (slaves) via the KNX bus. This ensures that it will be possible to subdivide the room into smaller rooms, without the need to change the wiring.

11.1 Send heartbeat and receive timeouts In a KNX network, S-mode and LTE mode communication objects can be exchanged between individual devices. The Receive timeout defines the period of time within which all the communication objects requested from a device must have been received at least once. If a communication object is not received within this period, a predefined value is used and an error message is generated. This ensures that interruptions in communication are identified at an early stage.

Shift value e.g. +3.0K (basic setting) Effective temperature setpoint, e.g. 23.0 °C (Mean value between heating and cooling setpoint).
Reset 13 KNX information 13.1 Reset and startup response A reset is initiated under the following circumstances: Processor failure(e.g. watchdog). After a power failure. After a bus power failure. Upon completion of a self test (using the communication object "StatusRequest"). Via ETS (without a startup delay): – After the download of the physical address. – After the download of the parameters. – Via ETS (menu Commissioning, Reset). • After parameter setting in ACS.
13.3 Startup delay After a reset, it takes up to 5 minutes for all the connected room controllers to restart. This is designed to avoid overloading the mains power supply when restarting. At the same time, it reduces the load on the KNX network, as not all controllers transmit data at the same time. The delay is determined by the controller's device address. 13.

14 FAQs Question: What happens if the parameter download process is interrupted? (power failure, bus failure etc.) Answer: The parameter set loaded into the controller will be incomplete. The controller will not start up properly. For example, the fan may run but the valves do not open. You will have to download the parameters again.
Question: Why does a controller with thermal valves not respond immediately when it is enabled in the plant graphics in the ACS view and in the Desigo graphics? Answer: After start-up, the thermal valves are preheated first. This is not shown in the plant graphics. However, if the room temperature is outside the dead band during this period, the fan switches to Speed 1. Question: Why doesn’t the master/slave binding work? Answer for LTE mode: Master/slave zones must be identical for master and slave.
15 Integrate RXB in Desigo/Synco Combinations of RXB controllers with Synco and a Desigo integration are possible and certainly make sense. However, certain combinations must be excluded; for others, certain boundary conditions must be respected. In the following sections the most common combinations are presented. Key Display Time scheduler 10385D69 Heating demand Cooling demand 15.

15.3 Case 3: Display in Desigo, with shared Synco time scheduler • Communication: – between controllers – with Desigo: • RXB display: • Synco display: • RXB time scheduler: • Energy demand: STOP Important note LTE mode via zones Individual addressing or S-Mode Desigo Desigo from Synco to Synco The Desigo time scheduler must be disabled by a specialist. Reason: Integration by means of individual addressing treats the time scheduler and display as one package. They subsequently need to be separated.
15.4 Case 4: Display in Desigo/Synco, with shared Synco time scheduler • Communication: – between controllers – with Desigo: – with ACS: • RXB display: • Synco display: • RXB time scheduler: • Energy demand: STOP Important note LTE mode via zones Individual addressing or S-Mode Individual addressing Desigo and ACS Desigo and ACS from Synco to Synco • The Desigo time scheduler must be disabled by a specialist. • In theory simultaneous display via Desigo and Synco is possible.

16 Working with different tools It is possible to prepare the RXB controllers in the office by setting the parameters in advance, so that only the physical address has to be entered on site. The HandyTool contains a “limited” parameter-setting option which can be used for this purpose. The preparatory work would then probably be carried out with ACS or ETS rather than with the HandyTool. Special caution is required (in relation to data consistency) when using more than one tool.
