7 1 Overview 1.1 RMZ792 bus operator unit RMZ792 bus operator unit Possible thanks to KNX User-friendly at all levels Functions The RMZ792 bus operator unit is a communicating operator unit allowing you to operate devices from the Synco range in a KNX network. The operator unit can be used both for fixed installation and mobile use (e.g. service). Third-party devices cannot be operated using the RMZ792 bus operator unit. The RMZ792 operator unit allows for central access to Synco 700 control units and central communication units as well as RX.. room controllers and RD.. room thermostats via the KNX bus. Menu-assisted operation using clear text provides for user-friendly and easy access at all levels for users as well as engineering and service staff. The RMZ792 bus operator unit used identical operating elements and the typical Synco operating philosophy such as RMZ790 and RMZ791 operator units for local operation, thus without KNX communication. Operation of up to 150 devices. Supported devices: RM.. control units. (Synco 700 range) RXB2.. and RXL2.. room controllers. RDG.., RDF.., RDU341 room thermostats. QAW740 room unit. OZW771, OZW775 central communication units. Automatic device search within line/area. Access allowed at both user and service levels. Display and acknowledge faults from all devices (bus devices). Freely definable passwords for all access levels. 20 customizable Favorites pages. Supply from KNX bus or external AC 24 V. Fixed installation (front, wall mounting), and mobile use as hand-held device. 1.2 Operator units RMZ79.. operator units The 3 RMZ79.. operator unit types differ with regard to shape, number or operable devices, functional scope, and type of use and site.

11 1.7 Notes This symbol draws your attention to special safety notes and warnings. Failing to observe these notes may result in injury and/or serious damages. Field of application Intended use Electrical installation Commissioning Operation Wiring Storage and transport Maintenance Faults You may use the devices listed in Section 1.4 only to control and monitor heating, ventilating, air conditioning, and chilled water plants. Trouble-free and safe device operation presupposes transport, storage, mounting, installation, and commissioning as intended as well as careful operation. Fuses, switches, wiring and earthing must comply with relevant national safety regulations for electrical installations. Only qualified persons trained by Siemens or its delegates may prepare for use and commission the devices. The devices may only be operated by staff instructed by Siemens or its delegates and who understand the potential risks. When wiring the system, strictly segregate the AC 230 V section from the AC 24 V safety extra-low voltage (SELV) section to protect against electric shock hazard! Refer to the environmental conditions specified in the respective data sheets for storage and transport. If in doubt, contact your supplier or Siemens. The devices are maintenance-free and only require regular cleaning. We recommend removing dust and dirt from system components installed in the control panels during standard service. Call service staff responsible for your plant in case of system faults; do not diagnose and correct faults. Only authorized staff may diagnose and correct faults and recommission the plant. This applies as well to work carried out within the panel (e.g. safety checks or replacement of fuses). Disposal Devices contain electrical and electronic components; do not dispose of them in the household garbage. Comply with all local, applicable laws. Building Technologies 1 Overview /58

12 2 Operation The devices may only be operated by staff instructed by Siemens or its delegates and who understand the potential risks. 2.1 Bus operator unit functions The bus operator unit allows for all operations (set and read data point values). The settings are transferred to the device in the KNX network (bus device), processed and saved in the device. The bus operator unit does not save data. The read values for the user are generated in the device and transferred to the bus operator unit. All devices whose device descriptions are saved in the bus operator unit can be operated. 2.2 Operating concept Basic principles All setting and readout values are arranged as data points (operating lines) in a software menu tree. Using the operating elements, every data point can be selected, displayed or set. The LCD shows all menus as clear text. The bus operator unit contains several programmed languages. The required application is enabled in the commissioning phase (see installation instructions, G3113). Operator elements RMZ792 bus operator unit 1 Display 2 INFO button Function 1: Retrieve important plant data. Function 2: Retrieve explanations on individual data points in the current menu. 3 OK press-and-turn knob Turn: Select operating line or readjust value. Press: Confirm operating line or setting. 4 ESC button Return to the previous menu Cancel value adjustment. 5 Fault button " " with LED LED: Fault display. Press: Acknowledge or reset fault. 12/58 Building Technologies 2 Operation

13 Background lighting The backlit display automatically switches on when using one of the operating elements. It switches off and the start page is displayed when inactive for 30 minutes. In the event of a pending fault, the fault information page is displayed rather than the start page. Display examples Start page Device list, partly with fault symbol Pop-up, set numerical value Help picture with explanation on the selected setting parameter 2.3 Operating levels We differentiate between the following operating levels: Level Symbol Description Info level The INFO button accesses the Info level. Information on menus and data points is displayed for as long as the button is pressed. The Info level allows for retrieving important plant data (fault and service information). No values can be adjusted. Access at the Info level is possible any time and not password-protected. User level The user level is set up as a menu. It allows you to read data points and/or change their values. The user level can be protected using a password against unauthorized access. No password is set when delivered. This level allows for accessing the user level of the bus devices. Building Technologies 2 Operation /58

14 Level Symbol Description Service level The service level allows for accessing other advanced menus and data points of the bus operating device. The service level can be protected using a password against unauthorized access. No password is set when delivered. The service level of the bus operator unit allows for accessing the service level of the bus device, e.g. the parameter settings of the control devices, or information on plant maintenance. Password level The password level offers additional menus and data points to configure and commission the bus operator unit. The password level can be protected using a password against unauthorized access. The password is set to "7" when delivered. Access to the password level of bus devices is not possible from this level. The setting is local only. All operation is menu-based; only the Info level does not use menus. The menus and operating lines are enabled according to access levels. A higher access level also shows the menus and operating lines for the lower access levels. The password level contains the entire menu. A corresponding symbol at the top left shows the active level. Navigate between operating levels Go to the Info level: 1. Press the ESC button repeatedly until the start page is displayed. 2. Press the INFO button or the press-and-turn button to go to the Info level. 3. For navigation within Info pages, repeatedly press the INFO button or the OK press-and-turn button. Go to the user level: 1. Press the ESC button repeatedly until the start page is again displayed. 2. Press the press-and-turn button "OK": 3. If the user level is password-protected, the Access levels menu is displayed. 4. Turn the OK button to select the User level and confirm by pressing the button. 5. Enter the password for the corresponding access level. 6. Press the OK button to confirm the password. Go to the service or password level: 1. Press the ESC button repeatedly until the start page is again displayed. 2. Press both the OK and ESC button simultaneously. The Access levels menu is displayed. 3. Select the desired access level by turning the OK button and press to confirm. 4. Enter the password for the corresponding access level. 5. Press the OK button to confirm the password. The device automatically returns to the start page and the user level if no action occurs within 30 minutes. 14/58 Building Technologies 2 Operation

15 2.4 Menu tree The menu tree of the bus operator unit has three different menus: 1. Info: No values can be changed. The pages are located at the Info level and can thus not be password-protected. 2. Devices: Device list with all bus devices. The menu for a bus device can be opened via the device name. As an alternative, customized Favorites menus provide to key and commonly used data points of bus devices. The data points can be changed and displayed individually. As an option, the menus can be protected using a password (user level) against unauthorized access. 3. Local menus: All bus operator unit settings are entered via local menus. These settings do not apply to bus devices listed in the device list. The menus are visible at the current operating level and password-protected by the passwords of both service and password levels.

16 3 Device operation The bus operator unit provides access to data points of the user and service levels for KNX network devices. Access to the data points of the password level is possible only using local operator units RMZ790 and RMZ791. The bus operator unit does not allow for configuring and commissioning bus devices. 3.1 Device list navigation The device list is generated during commissioning (list of all bus devices). Data points, with the exception of Favorites pages, are always accessed via the device list; see Section 3.2. Select the desired device from the device list to open the device's menu tree. The menu tree and navigation are the same as for local operation using RMZ790 or RMZ791. The following information is displayed when you press the INFO button: Device names and, if set accordingly, device address. Current position in the menu tree (path). Long text for the selected data point. The information is displayed as long as the button is pressed. 3.2 Fast access using Favorites pages The Favorites pages allow for customized user interfaces for daily operation. Favorites pages allow you to combine data points of any devices from the device list. The data points are copied from their position in the menu tree of the corresponding device to the desired Favorites page. This makes navigation more efficient. The symbol at the upper right corner identifies Favorites pages. This allows you to quickly differentiate between Favorites pages and a device's menu tree. 16/58 Building Technologies 3 Device operation

17 3.3 Data point display (visibility) The bus operator unit's interface only displays data points for the Synco 700 control units needed for the current device configuration. In the case of other devices (e.g. RX.. room controller), the bus operator unit displays all data points regardless of configuration. As a result, data points may not reflect real values or setting values may not trigger any action, as the current device's configuration may not support them or may be ineffective. 3.4 Troubleshooting Possible cases Fault / Fault status message Caution! Device version not supported Caution! Device not responding Data does not show real value (e.g. room temperature C). Setting has no effect. Cause / Solution The device list for the bus operator unit and the software version of the target device may not match, or the device is not supported. Determine which versions of bus operator unit and target device are compatible. See Valid Version Set, J3100. Exchange bus operator unit or target device. No communication with target device. Is the device operating? Is the device connected to the KNX bus? Was the device address changed? The data point in the current configuration is useless (device does not support data point visibility). The data point in the current configuration is useless (device does not support data point visibility). 3.5 Customized texts Customized device texts are taken over, i.e. the bus operator unit display is identical to that on the local operator unit (RMZ790/791). The bus operator unit reads the customized text from the corresponding device. The factory-set default text is displayed until the customized text is received. Building Technologies 3 Device operation /58

18 4 Supply The bus operator unit can be supplied in three different ways: Supply from KNX bus (power consumption 45 ma). External supply (from external AC 24 V supply). Supply from Synco 700 control unit (from service interface of the Synco device; use only in exceptional cases). 4.1 Supply from KNX bus If the bus operator unit is used at a place where there is no external AC 24 V supply (e.g. mobile use), the bus operator unit can be supplied via the KNX bus. The slider on the rear of the bus operator unit must be set to "KNX". For the bus operator unit, calculate 45 ma supplied by the KNX bus. To this end, at least 2 Synco control units with decentralized bus supply must be activated, or a central power supply is required (see also document P3127). The bus operator unit is connected using the delivered cable to - a KNX bus plug (figure a) or - a Synco 700 control unit (figure b), or The KNX bus lines (terminals CE+ and CE ) are wired in the floor of the housing (figure c, watch out for polarity). a) b) c) G G0 CE+ CE KNX S KNX S1 G G0 CE+ CE KNX S KNX 3113A05 S1 45 ma G CE+ G0 CE KNX KNX S KNX S1 3113A07 X1 Synco RM...

19 4.2 External supply We recommend AC 24 V external device supply for fixed installation (e.g. on control panel door). In this case, the decentralized/central bus supply does not have to carry the power load required by the bus operator unit, which is thus available to other bus devices. AC 24 V voltage is required to power the bus operator unit externally. It must meet requirements for SELV/PELV (safety extra low-voltage). The transformers used must be safety isolating transformers featuring double insulation as per EN or EN , designed for 100% duty. The slider on the rear of the bus operator unit must be set to "EXT". AC 24 V is supplied to the bus operator unit via terminals G and G0. SP KNX AC 24 V G G0 CE+ CE KNX S EXT SN 3113A Supply via Synco 700 control unit Important note In exceptional cases, power may be supplied to the RMZ792 bus operator unit via a Synco 700 control unit. A Synco 700 control unit can only supply power for a bus operator unit if it features 3 or more extension modules. The slider on the rear of the bus operator unit must be set to "EXT". The bus operator unit is plugged into the service interface of the Synco 700 control unit using the supplied cable. G CE+ CE KNX S EXT 3113A06 G0 S1 Synco RM... N1 45 ma KNX TP1 Fault status messages from extension modules may be displayed when the bus operator unit is plugged in during plant operation. The faults may result in short-term interruption of plant operation. You must acknowledge and reset the fault status messages. Building Technologies 4 Supply /58

20 4.4 Troubleshooting Possible cases Faults Bus operator unit does not start. Bus operator unit restarted cyclically. KNX bus blocked. Operating values of bus devices not displayed properly or cannot be changed. Background illumination of display very low. Control unit signals extension modules' failure, some plant parts fail. Cause / Solution Wrong polarity CE+ / CE Insufficient power supplied by KNX bus (undersized bus supply, bus voltage too low). Wrong switch setting ("KNX"/EXT") or switch in illegal intermediate position. RJ45 plug not snapped in (no contact). The slider is set to "EXT" and the bus operator unit was plugged in during plant operation. Solution: 1. Acknowledge or reset fault status messages. 2. Switch off operating voltage to the control unit, then plug in bus operator unit and switch on operating voltage or 3. Plug in the bus operator unit to a control unit without extension modules (switch off operating voltage prior to plugging in, then plug in bus operator unit, and then switch on operating voltage). 20/58 Building Technologies 4 Supply

21 5 Commissioning Only qualified persons trained by Siemens or its delegates may prepare for use and commission the devices. 5.1 Start commissioning Initial commissioning See installation instructions G3113, supplied with the bus operator unit, for initial commissioning. For initial commissioning, the bus operator unit starts with menu Language. This allows you to select the country-specific language. Then Commissioning menu is now displayed. The access level is set to "Password level". After selecting the country-specific operating language and confirming the selection by pressing the OK button, the Commissioning menu opens; see Section Set user level Set the user level (access level for plant operator) when done with commissioning: 1. Select the start page: Press the ESC button repeatedly until the start page is displayed. 2. Press both the OK and ESC button simultaneously. The Access levels menu is displayed. 3. Press the press-and-turn button "OK": 4. Turn the OK button to select the User level and confirm by pressing the button. 5. Enter the password for the corresponding user level. 6. Press the OK button to confirm the password. Building Technologies 5 Commissioning /58

22 6 "Commissioning" menu Notes Only staff trained by Siemens with associated permissions (access rights) may commission (configure) the RMZ792 operator unit. The RMZ792 bus operator unit does not allow for commissioning (configuring) the devices in the KNX network. Commissioning must occur locally on the device (bus device) in the KNX network using the RMZ790 or RMZ791 operator units or centrally using the OCI700.1 service tool. See the installation instructions for initially starting and commissioning the RMZ792 bus operator unit. The bus operator unit works smoothly if the device address of all bus devices is right. This means that the device address of all bus devices and area/line couplers must correspond to their position in the network topology (area.line.address). Wrong device addresses result in errors when commissioning the bus operator unit. 6.1 Device address The RMZ792 bus operator unit, similar to all other bus devices, requires a unique device address. There are 3 ways to set the device address: One of the methods always reflects the best method depending on use. The device address is factory set to default (area.line.address). A bus operator unit with device address 255 does not send out process data (this applies to all devices with device address 255). Device addresses 253 and 254 are reserved for special devices Automatic address search Automatic address search is ideal if the bus operator unit is installed retroactively in an existing plant without knowing the existing address allocation. When prompted by the operator, the bus operator unit gets the subnetwork address (SNA, comprising area and line) from the higher line coupler. The last setting for area and line is taken over if no subnetwork address is received. The bus operator unit now attempts to find a free device address within the line, starting from 252. The attempt is repeated for an address lower by 1 if the address is taken already. The search is continued until a free device address is found. If no free device address is found, the address retains value /58 Building Technologies 6 "Commissioning" menu

23 6.1.2 Manual address allocation Manual address allocation is sensible when the bus operator unit has a fixed location in the KNX network, and if the address has already been defined and is known from the network plan. Area, line and device address are entered manually by the operator. The bus operator unit gets the subnetwork address (SNA, comprising area and line) from the higher line coupler in the event of change to either area or line. If the line coupler supplies the SNA, the device assumes the line coupler's SNA and overwrites any existing manual settings. The manually entered value is accepted if no SNA is received. The setting value is reset to the previous value if the desired device address is used by another device Allocate addresses using ETS Allocating addresses using ETS (Engineering Tool Software) makes sense if this tool is used in general to allocated addresses in the KNX network. Area, line, and device address are preset in ETS. On the bus operator unit, set the Programming mode to On. Load the device address using ETS. Programming mode automatically returns to Off after an address is allocated to the bus operator unit Troubleshooting Possible cases Faults No communication with other bus devices. Subnetwork address (SNA) not assumed from higher line coupler. Fault status message 6001 >1 identical bus address Cause / Solution Device address has value 255, i.e. no active communication. Set the device address to a value between 1 and 252 (automatic search or manual entry). The subnetwork addresses (area and line) of the line couplers and/or bus devices do not match. Check the subnetwork addresses and reallocate as needed. There is no higher line coupler or the line coupler is configured to not send the SNA to the line. Configure the line coupler accordingly or manually specify the SNA. The network contains several bus devices with identical device address. Correct the device addresses on the related devices. 23/58 Building Technologies 6 "Commissioning" menu

24 6.2 Enable communication Communication is active when: The device has a valid device address. A bus power supply is available. The device is not in the Commissioning menu "Communication" submenu Fundamentals Operating lines See basic documentation P3127, "Communication via KNX bus", for a detailed description of communications. You must have basic knowledge of device addresses and network topologies. Main menu > Commissioning > Communication Area Line Device address Search address --- / Address found --- Programming mode Off / On Off Setting values Area, Line and Device address allow for defining individual device addresses. Automatic address searches are triggered via operating line Search address. Successful address searches are acknowledged with status Address found. Status Address failed means that the address search was unsuccessful. Programming mode must be set to On to allocate addresses in ETS. ETS automatically resets the value to Off after successful address allocation. Notes If a higher line coupler in the network topology supplies SNA information different from the values set for area and line, the line coupler's values are assumed. An error message is triggered if the device address for 2 devices is identical. 6.3 Device list Definition Layout The list of operable bus devices is referred to as Device list. The menu tree of the bus device is opened from the bus operator unit's device list. Bus devices not listed in the device list cannot be operated using the bus operator unit. Bus devices are listed as follows in the device list: 24/58 Building Technologies 6 "Commissioning" menu

25 Information B.L.A Name Status Description Symbol for bus device KNX device address (optional): B : Area [0 15] L : Line [0 15] A : Address [1 255] See also Section 6.3.2, "Display list" submenu. Device name: Heating : Text, max.20 characters ("Heating" is a mere example!) : Device without names! : Name of the device cannot be read See also Section 6.3.7, "Name devices" submenu. Device status: : Device ok, no faults : Device fault : Status read from device : Status cannot be read, possible failure or in commissioning mode See also Section , Device list in the "Main menu". Functions Various functions allow for creating a customized device list reflecting operator needs and requirements: Automatic device search within line/area. Retroactive addition of additional devices: Individual device. All devices within a line. All devices within an area. Delete individual devices from the device list. Assign or change device names in the device list. Determine the device presentation within the device list. Change the order of devices within the device list. Delete the entire device list. The following status messages may be displayed upon device list operations and dependent on the menu: Status messages Description --- Command not yet executed. Command being executed. Searched for Device list created successfully. Added Devices added to list successfully. Address invalid Searched for device does not exist or does not respond. Sorted Device list sorted successfully. Deleted Device list deleted successfully. Rejected Device search not possible due to current area and line settings. Building Technologies 6 "Commissioning" menu /58

26 6.3.1 "Create list" submenu Application Operating lines When the bus operator unit is newly connected to the plant. When the bus operator unit is connected temporarily to the plant as a service device. Main menu > Commissioning > Device list > Create list Area Line * / Start search --- / Searched for --- Number of devices current The network is searched for operable devices as per the set parameters. An existing device list is listed in advance. Device searches are possible only within the selected area. The settings for Area and Line restrict the search for bus devices to the desired portion of the network. This also reduces the search time. Setting * for line means that all lines of the desired area are searched for devices. The search in this case lasts ca. 15 minutes and cannot be interrupted. Operating line Start search starts the device search. The number of devices found is displayed by the value Number of devices current. Important note Notes When creating a device list, any existing devices, device names, and Favorites pages are deleted! The device list can include max. 150 devices. If a network has more than 150 bus devices, the search is stopped after 150 devices. Menu List information displays List error with List complete. In plants featuring several bus operator units, only one device can carry out a search at any given time. The device search across all lines (Line = *) is possible only within the bus operator unit's own area. The settings for Area and Line must not be changed during a device search. If power is interrupted during a device search or if the bus operator unit is unplugged during the device search, the device list is declared List invalid. All commands are ignored during a device search. The local names of the devices are added to the list when creating the device list. Subsequent, local changes to a name are on the device are not updated automatically in the device list. 26/58 Building Technologies 6 "Commissioning" menu

35 7 Data backup Application Create a backup for the settings. Restore backed up settings following unsuccessful changes. Back up or restore settings when exchanging the bus operator unit. Function The bus operator unit's settings can be backed up after commissioning. These settings can be later restored e.g. following unauthorized or erroneous changes or deletion of settings. Data are backed up or restored via 2 different locations: Locally via the internal memory of the bus operator unit. Using a second device, i.e. the internal memory of a second bus operator unit connected to the KNX bus. Backing up to a second device is sensible especially when the bus operator unit needs replacement due to compatibility issues. Backed up settings Backup stores the following settings: Device list including device names, order, and display format. Favorites pages along with all data points. Names and order of Favorites pages. Display settings for fault status messages on the bus (see Section 8.5, Display bus fault status messages). No other settings (device address, language, etc.) are saved. Note The bus operator unit restarts following successful restoration of settings. The following status messages are displayed dependent on the respective action: Status messages Description --- Command not yet executed. Restored Settings restored successfully. Saved Settings backed up successfully. Failed Error while backing up or restoring data. Building Technologies 7 Data backup /58
