2 Enhanced comfort and energy efficiency in hotels with Synco and GAMMA building systems Requirements Single source Types of integration Purpose of the document Structure of the document Synco with special group addresses Engineering notes Hotel buildings require special technical solutions. What is needed are low construction costs, a high level of flexibility to be able to easily rearrange spaces, economical operation and, naturally, excellent comfort for the guests. The buildings must ensure optimum working conditions, low energy consumption, safe operation, protection from damage, and security in emergency situations. Building systems based on conventional technology cannot satisfy most of these requirements. As a supplier of products and systems for all sectors of building automation and control, Siemens offers integrated, energy-efficient and tested solutions from the production of heat and cooling energy to individual room control and from energy distribution to the power outlet in the hotel room, thus meeting all requirements. There are different types of integrated applications: "Integrated room applications" comprise HVAC, lighting and shading control with the option of manual intervention from the room "Integrated room primary applications" comprise HVAC, lighting and shading control with the option of manual intervention from the room, but also including a connection to primary plant, which ensures optimum communication between the room and the heating/refrigeration plant guaranteeing maximum energy efficiency The present Application Manual describes 7 variants of a guest room in a hotel and one variant each of lobby, restaurant, fitness room, and primary plant. With all applications, the focus is placed on energy efficiency and comfort. The different variants offer room automation with fan coil units, radiators and floor heating systems as well as ventilation and VAV plant with a host of products from Siemens KNX range: From simple solutions with fan coil units including switching of electric circuits to VAV systems for larger rooms with automatic lighting and blind control. Manual control is always possible. There is no need to worry about energy savings since these are automatically ensured by the system. Moreover, the best climatic and lighting conditions are guaranteed for all sections of the hotel. Each application variant is subdivided into the following sections: Features/benefits Room setup Device list Function description Secondary documents Synco devices use standard group addresses to distribute system time and information about plant malfunctions. When an application program is downloaded to the Synco devices via ETS, the group addresses are deleted. For this reason, the special group addresses must be downloaded via ETS. Otherwise, the Synco devices will not be able to communicate. The group addresses can be downloaded from the Internet at This document describes examples of room applications and makes proposals for their implementation.

8 Scenarios for hotel rooms For hotel rooms, the following usage scenarios are considered realistic: HVAC A typical HVAC scenario could look as follows: When a room is not occupied, it operates continuously in Economy mode. The moment the guest checks in, the hotel reservation system switches the room s operating mode from Economy to Precomfort. As long as the room is not occupied, its temperature is maintained at the Precomfort setpoint (20 C for heating/26 C for cooling). When the guest enters the room, its temperature is raised to the Comfort level of 21 C in the case of heating/lowered to 24 C in the case of cooling, and then lowered/raised again when the guest leaves the room. When checking out, the room s operating mode is reset to Economy. The guest can adjust the Comfort setpoint to meet his/her individual needs. But when automatically switching to another operating mode, the setpoints are reset to those of the room group. Lighting A typical lighting scenario could look as follows: When the hotel card is inserted, the basic lighting is switched on. Then, other lights can be switched on manually via the pushbuttons. When leaving the room, all lights are automatically turned off after a certain period of time. Shading A typical blinds scenario could look as follows: When the room is not occupied, the blinds are controlled automatically. In the winter after sunrise, the blinds are automatically raised, allowing solar heat to enter the room. On the other hand, when, in the summer, the sun shines on the façade, the blinds are lowered to protect the room from solar heat. For safety reasons, the blinds are automatically lowered after sunset. When the room is occupied, it is up to the guest to control the blinds. Then, automatic operation is deactivated and the blinds can be controlled via the pushbuttons or the room operator unit. 9

9 Hotel-specific functions The functions described below are used primarily in hotels: SOS Alarm function The alarm function can be triggered via pushbutton. When pressed, a signal is sent to the management station. The alarm can be visualized on a suitable display unit (touch panel or webbrowser) or on a panel with signal lamp. The operating elements provided are rockers with "Bell" symbol and pull cords. MUR Make up room The MUR function is activated via pushbutton. When pressed, a signal is sent to the management station. The signal can be displayed on a suitable display unit (touch panel or webbrowser) or can be indicated by a signal lamp on a panel. DND Do not disturb The DND function is triggered via pushbutton. Indication is by signal lamp, inside and outside the room. Minibar Monitoring of minibar Monitoring of the minibar can be implemented by a window contact fitted to the door of the minibar and a pushbutton interface. When the minibar door is opened, a signal is sent to the management station and logged on the UP 588 touch panel as a trend. When using Synco 700 devices (RMB795B, RMS705B), opening the door can either be counted or logged as an event. In each case, 4 channels available. Hotel booking system Integration in hotel booking system Integration of an OPC server with suitable, commercially available software facilitates the connection from the KNX bus to the Micros Fidelio/Opera hotel management system. This makes it possible to automatically switch the hotel room s operating mode when guests check in or out, or based on the booking plan. Fire protection and smoke extraction Shutdown, ventilation or smoke extraction in the event of fire Use of the central control unit RMB795B in connection with the fan coil unit applications allows ventilation to be automatically shut down in the case of fire or to switch on smoke extraction, if required. The sensors are connected directly to the RMB795B. The respective signal is forwarded to the ventilation controller (RMU7x0B) via the KNX bus. On VAV applications, the signal is also fed to the room thermostat or the VAV controllers, which ensure that the VAV dampers will be correctly closed or opened. 10

Every room sends its heat/cooling energy request to the heating/refrigeration plant. These plants are controlled depending on the outside temperature and the heat/cooling energy requests received from the rooms. During nonoccupancy times (rooms not booked), the room temperatures are automatically lowered via the integrated hotel booking system. Open windows are always automatically detected and the temperatures of such rooms are lowered/raised to save heating/cooling energy. The room temperatures are also slightly lowered/raised during the day, if the guest is not present. Lighting control Presence detectors (hotel card switches) help save energy by automatically switching lighting off when the room is not occupied. Blinds control When a room is not booked (or, if desired, when the guest is absent), a weather station outside the building protects up to 4 façades from extreme sunlight in the summer. This function helps to keep the rooms cool. The weather station also protects the blinds from damage caused by strong winds or other natural influences. On sunny winter days, the weather station raises the blinds to let solar radiation make a natural heat contribution. When the guest is present, the blinds can be controlled via the pushbuttons and automatic operation is off. Remote control Integration of a webserver facilitates remote control and monitoring on a PC or smartphone via webbrowser. 13

13 Application Manual Nr. 01 Function description Description of functions Individual room temperature control The room thermostat (RDF) acquires the temperature, controls it via the fan coil unit and calculates the demand for heat or cooling energy. The resulting signal is forwarded to the primary controller via the KNX bus. Time program and hotel booking system Time programs for up to 10 rooms or room groups can be defined in the central control unit (RMB). A time program sets the periods of time the room is not used. During these time periods, the operating mode is set to Protection, resulting in a lower temperature setpoint. After that, the setpoint is raised to the Economy level. Room automation can also communicate with the hotel s booking system. When the guest checks in, the room temperature is prematuraly raised to the Comfort level. During the periods of time the hotel is closed or in non-booked rooms, valuable heating energy is automatically saved by changing the operating mode to Economy. Window contact If one or several windows of a room are opened, the operating mode changes automatically to Economy. This means that heating or cooling energy is saved since the system does not try to compensate for energy losses. Presence-dependent heating control When the presence detector (hotel card switch) signals room occupancy, the room temperature is raised to the Comfort level. Then, it is lowered again to the Economy level. Presence-dependent lighting control When the room is no longer occupied, lighting is automatically switched off. Blinds control The weather station (AP257/32) with its built-in GPS receiver measures solar radiation and controls shading to protect the façade against sunlight. Up to 4 façades can be selected for automatic and individual control. In cold winter nights, the blinds are lowered to improve the building s thermal insulation. On sunny winter days, the blinds are raised, allowing sunlight to enter the room so that energy is gained. When the room is occupied, automatic operation is deactivated. The blinds can then be operated via the pushbuttons. Protection of blinds The weather station acquires continuously the wind speed. If strong winds occur, the blinds are raised to a secure position. Remote control and monitoring Using a webbrowser, all rooms can be controlled and monitored via webserver (OZW). The following parameters can be monitored: Current state of windows and doors Current room temperatures Current room temperature setpoints Current operating modes If required, the following parameters can be changed: The room operating modes, individually or in groups The room temperature setpoints, individually or in groups The time program for every room or for groups of rooms Display of energy efficiency The OZW772 webserver is able to display the HVAC system s energy efficiency, which reminds the user if from the point of view of energy efficiency settings beyond the permitted limits were made. If nonefficient operating states occur, the user is notified via or smartphone app. The limit values can be set by the user. 14

This function helps to keep the rooms cool. The weather station also protects the blinds from damage caused by strong winds or other natural influences. On sunny winter days, the weather station raises the blinds to let solar radiation make a natural heat contribution. When the guest is present, the blinds can be controlled via the pushbuttons and automatic operation is off. Remote control Integration of a webserver facilitates remote control and monitoring on a PC or smartphone via webbrowser. 18

18 Application Manual Nr. 02 Function description Description of functions Individual room temperature control The room unit (QAX) acquires the temperature and makes it available to the room controller (RXB) which controls the fan coil unit and calculates the demand for heat/refrigeration. The result of the calculation is sent to the primary controller via the KNX bus. In the bathroom, the AQR acquires and controls the temperature and feeds the positioning signal to the radiator s valve actuator. Time program and hotel booking system Time programs for up to 10 rooms or room groups can be defined in the central control unit (RMB). A time program sets the periods of time the room is not used. During these time periods, the operating mode is set to Protection, resulting in a lower temperature setpoint. After that, the setpoint is raised to the Economy level. Room automation can also communicate with the hotel s booking system. When the guest checks in, the room temperature is prematuraly raised to the Comfort level. During the periods of time the hotel is closed or in non-booked rooms, valuable heating energy is automatically saved by changing the operating mode to Economy. Window contact If one or several windows of a room are opened, the operating mode changes automatically to Protection. This means that heating or cooling energy is saved since the system does not try to compensate for energy losses. Presence-dependent heating control When the hotel card switch signals room occupancy, the room temperature is raised to the Comfort level. Then, it is lowered again to the Precomfort level. Presence-dependent lighting control When the room is no longer occupied, the lighting and individual electric circuits are automatically switched off. Blinds control The weather station (AP257/32) with its built-in GPS receiver measures solar radiation and controls shading to protect the façade against sunlight. Up to 4 façades can be selected for automatic and individual control. In cold winter nights, the blinds are lowered to improve the building s thermal insulation. On sunny winter days, the blinds are raised, allowing sunlight to enter the room so that energy is gained. When the room is occupied, automatic operation is deactivated. The blinds can then be controlled via the pushbuttons. Protection of blinds The weather station acquires continuously the wind speed. If strong winds occur, the blinds are raised to a secure position. Remote control and monitoring Using a webbrowser, all rooms can be controlled and monitored via webserver (OZW). The following parameters can be monitored: Current state of windows and doors Current room temperatures Current room temperature setpoints Current operating modes If required, the following parameters can be changed: The room operating modes, individually or in groups The room temperature setpoints, individually or in groups The time program for every room or for groups of rooms Display of energy efficiency The OZW772 webserver is able to display the HVAC system s energy efficiency, which reminds the user if from the point of view of energy efficiency settings beyond the permitted limits were made. If nonefficient operating states occur, the user is notified via or smartphone app. The limit values can be set by the user. 19

The pressure setpoints of the ventilation system are shifted depending on the room s demand for supply air. Time program for every room Time programs for up to 10 rooms or room groups can be defined in the central control unit (RMB). A time program sets the periods of time the room is not used. During these time periods, the operating mode is set to Economy, resulting in a lower temperature setpoint. Hence, valuable heating energy can be saved during the night and on days of rest. After that, the setpoint is raised to the Precomfort level. Presence-dependent heating control When the presence detector signals room occupancy, the room temperature is raised to the Comfort level. Then, it is lowered again to the Precomfort level. Constant light control Constant light control maintains room lighting at a constant brightness level by adding artificial light to daylight. Brightness is automatically and continuously adapted by dimming up/down the lighting groups. Offset adjustments allow the configuration of constant light control with only one presence detector. Manual switching and dimming is made possible via the pushbutton. In this case, lighting control is stopped and the brightness level in the room is maintained as long as presence is detected. Presence-dependent lighting control The presence detector (UP258E21) allows up to 4 lighting groups to be switched and controlled and detects presence within its range. If persons are detected, lighting is switched on at the required brightness level. When the persons leave the room, the lighting is switched off again. To extend the monitored range, a master-slave configuration can be implemented. Blinds control The weather station (AP257/22) with its built-in GPS receiver offers efficient control to protect the façade against sunlight. Automatic and individual control of up to 8 façades can be provided. Sun tracking control and shadow outline tracking are another 2 functions that ensure maximum usage of daylight and minimum glare in the room. Sun tracking control continuously adjusts the slats in a way that their position is always at a right angle in relation to the sun. Shadow outline tracking controls the position of the blinds such that the edge of the shadow always maintains the same distance to the window. This optimizes daylight usage, thus reducing the amount of energy required for the lighting. In cold winter nights and when nobody is present in the room, the blinds are lowered to improve the building s thermal insulation. On sunny winter days, the blinds are raised, allowing sunlight to enter the room so that energy is gained.. Protection of blinds The weather station acquires continuously the wind speed. If strong winds occur, the blinds are raised to a secure position. Remote control and monitoring Using a webbrowser, all rooms can be controlled and monitored via webserver (OZW).

The heat/cooling energy requests from all rooms are forwarded to the heating/refrigeration plant and the individual VAV controllers. The ventilation controller controls the supply air temperature and the amount of air demanded by the VAV controller. The heating plant is controlled depending on the heat request from the ventilation controller and room thermostats plus the outside temperature. The refrigeration plant is controlled depending on the cooling energy request from the ventilation controller. Nonoccupancy times during the night can be set for every room in a time program. During these periods of time, the room temperatures are automatically lowered. Open windows are automatically detected and the temperature of these rooms is lowered to save heating energy. The room temperatures are also slightly lowered during the day, if the guest is not present. Lighting control Presence detectors (hotel card switches) help save energy by automatically switching the lighting off when the room is not occupied. A brightness sensor incorporated in the presence detector helps when switching and dimming lights, ensuring that the room is always optimally illuminated, using as little as possible artificial light. Blinds control 55

55 Application Manual Nr. 10 Fitness room room automation A weather station outside the building protects up to 8 façades from extreme solar radiation in the summer. This function helps to keep the rooms cool. The weather station also protects the blinds from damage caused by strong winds or other natural influences and controls them at dusk and according to temperatures to save heating energy during winter nights. Finally, sun tracking control and shadow outline tracking allow a maximum of natural light to enter the rooms, offering optimum working conditions. Remote control Integration of a webserver facilitates remote control and monitoring on a PC or smartphone via webbrowser. Function description Description of functions Individual room temperature control The room thermostat (RDU/RDG) acquires the temperature and controls valve actuator STA23 of the floor heating system. When the room calls for heat/cooling energy, the room thermostat sends a heat request to the heating controller and/or a request for more warm/cold air to the VAV controller. Indoor air quality control The CO 2 sensor acquires the indoor air quality and forwards its signal to the ventilation controller which controls the proportion of fresh air. Demand-dependent supply air temperature control The primary ventilation controller (RMU) controls the supply air temperature and the volumetric air flow depending on the request for heat/cooling energy from the room thermostat and the request for volumetric air flow from the VAV controller. The pressure setpoints of the ventilation system are shifted depending on the room s demand for supply air. Time program for every room Time programs for up to 10 rooms or room groups can be defined in the central control unit (RMB). A time program sets the periods of time the room is not used. During these time periods, the operating mode is set to Economy, resulting in a lower temperature setpoint. Hence, valuable heating energy can be saved during the night and on days of rest. After that, the setpoint is raised to the Precomfort level. Presence-dependent heating control When the presence detector signals room occupancy, the room temperature is raised to the Comfort level. Then, it is lowered again to the Precomfort level. Constant light control Constant light control maintains room lighting at a constant brightness level by adding artificial light to daylight. Brightness is automatically and continuously adapted by dimming up/down the lighting groups. Offset adjustments allow the configuration of constant light control with only one presence detector. Manual switching and dimming is made possible via the pushbutton. In this case, lighting control is stopped and the brightness level in the room is maintained as long as presence is detected. Presence-dependent lighting control The presence detector (UP258E21) allows up to 4 lighting groups to be switched and controlled and detects presence within its range. If persons are detected, the lighting is switched on at the required brightness level. When the persons leave the room, the lighting is switched off again.
