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 You may use the devices listed in Section 1.4 only to control and monitor heating, ventilating, air conditioning, and chilled water plants. Intended use Trouble-free and safe device operation presupposes transport, storage, mounting, installation, and commissioning as intended as well as careful operation.
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.
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.
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.
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.
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).
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 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.
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).
4.4 Possible cases Troubleshooting Faults Cause / Solution Bus operator unit does not start. • 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). 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.
5 Commissioning Only qualified persons trained by Siemens or its delegates may prepare for use and commission the devices. 5.1 Start commissioning 5.1.1 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".
6 Notes "Commissioning" menu • 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.
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.
