HVAC Design Criteria
Typical Architecture for HVAC
Disadvantage of Standalone System
1. Centralized Control is not Possible.
2. Alarms cannot be monitored.
3. Optimization of the system is not possible.
4. Cloud based cannot be implement.
5. New Strategies using Energy Management Software's for increasing the building efficiency cannot implement.
HVAC systems can interface
to Building Automation System (BAS) to allow the
building owners to have more control over the
heating or cooling units. The building owner can
monitor the system and respond to alarms
generated by the system from local or remote
locations. The system can be scheduled for
occupancy or the configuration can be changed
from the BAS. Sometimes the BAS is directly
controlling the HVAC components. Depending on
the BAS different interfaces can be used
Today, there are also dedicated
gateways that connect advanced VRV / VRF and
Split HVAC Systems with Home Automation and
BMS (Building Management Systems) controllers
for centralized control and monitoring, obviating
the need to purchase more complex and
expensive HVAC systems. In addition, such
gateway solutions are capable of providing remote
control operation of all HVAC indoor units over the
internet incorporating a simple and friendly user
interface

Understanding Basic IP Addressing
Network Address
128.1
An IP address would look something like this
128.1.73.21 and is made up of two distinct parts.
The first part of the address, 128.1 is the Network
Address, this connects us to the correct network (like
the area code).
Host Address
73.21
The second part of the IP address, 73.21 is called the
Host address and this connects us to the correct device
(or Host).
The numbers used to make up an IP address are
normally between 0 and 254 (8 bit Logic).

Building automation is the automatic centralized control of a building's heating, ventilation and air conditioning, lighting and other systems through a building management system or building automation system (BAS). The objectives of building automation are improved occupant comfort, efficient operation of building systems, and reduction in energy consumption and operating costs and improve life cycle of utilities
Automation and Control Solutions is made of six business units. Trend is within the Environmental & Combustion Controls (ECC) business unit.
You will notice that each business unit has a peer to peer relationship and reports equally to the overall ACS division.
Since Trend was acquired in 2005 the question has come up from time to time “If Trend is a Honeywell company, then why don’t I just buy from Honeywell?”
If you are interested in purchasing a home security system you likely could be interested in purchasing an ADI security system from the Honeywell ACS Security business unit.
If you run a laboratory and are looking for fume hood controls, you likely would purchase lab controls from Phoenix Controls within the ECC business unit.
Maybe you oversee a county courthouse. You have a limited budget and are in need of major renovations. You may want to work with Honeywell Building Solutions (HBS) on a performance based contract to renovate mechanical systems, provide energy efficient lighting, EMS, and bundle in a new roof.
You may be looking to deploy infrastructure for a local or multi-site national / international energy monitoring and management initiative. Trend within the ECC business unit of ACS would be the right place to go and the next few slides will tell you why.
HMI software is a graphical, real-time, user interface for the building control system.
It enables the user to monitor plant or building services, and make changes to the way the building is controlled from a graphical display. All pages and actions are accessible using a mouse.
The security system ensures that the user is only presented with information and functions that are relevant to their authority or task.
Programming / Configuration tool is graphical method of configuring the controllers and writhing the programs within the controllers. It gives a powerful way of creating the Programs and support documentation.
In some cases the configuration and programming tool may be different.
It may also have a simulation and Live value commissioning features, with the help of which one can reduce the errors easily.
Nowadays, Most Energy Management Software have the capability to record and track the real-time energy usage of a building or floor, and to store that information for later analysis.
Features are explained in Energy Manager Section.
The Network Display would be a touch screen display which provides an interface to the Building Management system or any part of Building Management System. Network Display enables the user to view and adjust operating times, monitor alarms, make adjustments to controller parameters, and display graphs of logged data. Schematic displays provide the ability to view, change and graph data from colour graphics pages. Alarms can be sent directly to the IQView8 where they appear on a special display, an audible, and visual indication of the alarm is given.
The unit is panel or wall mountable with surface and embedded mounting options available enabling the IQView8 to be mounted in a way suitable for its environment and use.
Slide Shows the typical Pages which may be present on the Network Display.
Schematics :- The pages may contain a backdrop, graphic images, animations. multi state graphics (ON, OFF, waiting, error, alarm, overridden ON, and overridden OFF), and static text. The security system enables access to particular pages to be restricted so that users are only presented with the necessary information.
Operating Times :- The interface provides a common view for all types of controllers. An easy to follow wizard guides the user through the process of changing times and configuring exceptions.
Graphs :- Graphs can accessed from the schematic pages, from a list of values on the system (Controls Browser), or from the display and directory navigation (Views Browser). It is possible to zoom in on selected parts of the graph, display spot values, or view the underlying data.
Controls Browser :- The Controls Browser displays a list of sensor, digital input, critical alarm, knob, switch, time zone, driver, and loop modules Once the values are displayed they can be viewed, adjusted, or graphed as appropriate depending on the type of value.
Alarm Handling :- Alarm handling features available in the Alarm Browser notify the user of alarms that have occurred, A flashing alarm icon in the Title Bar indicates that an alarm has been received. Alarms are grouped into categories. The alarm actions for each category can be configured.

The challenge for brands is being able to identify the risks facing their brand online and taking action to protect against the threats they are facing
Currently, brand owners only know about approximately 10% of the threats facing their brand online
As a result, it is imperative that organizations adopt a proactive, precautionary attitude and introduce measures to expose the threats targeting their brand. To reduce the risks, brands must implement robust security measures and proactively monitor any online attacks or infringements so that threats can be addressed early, before any significant damage is done.
Trainer:
So what’s the risk?
Systems that are Internet facing and which may be vulnerable to a cyber intrusion which may be a result of weak system configuration, software that has not been updated to the most current version, and/or lack of additional security such as use of a VPN.
What’s the worst that could happen?
Switch the lights off in a supermarket?
Shut down the HVAC plant in a server room?
Or interact with the system in some ingenious manner?
Perspective is important!
Every system has different security considerations and risks
It is even important to remember on some sites it is easier to walk to the plant room and switch the plant off rather than attack the BMS system
As such different options & applications of the products should be considered
Unauthorised access can have financial ramifications.
VPN Agent Solution
This solution allows connection over the internet to the site via a secure VPN.
A PC running HMI Software, Programming Software tool can access the remote site over the VPN. The VPN Agent automatically connects to the remote site every time the PC on which it is installed is switched on. This is useful for remote alarm monitoring using 963.
With this solution, a modem is connected continuously connected to the remote site and all that is
required on the PC is an internet connection and the VPN Agent software. There is only 1 license included in the VPN Agent
software package, however additional licenses can be obtained on request (extra charges apply).
The diagram below illustrates the VPN Agent connected to remote TREND’s IQ4 controllers.
VPN Client Solution
This solution connects to the remote network in the same way as the VPN Agent. The only difference is that the VPN connection
to the remote site is not made automatically when the PC is switched on; the user must connect to the VPN Client manually
if they wish to access the remote site.
With this solution, a modem is connected using a time limited connection to the site and all that is
required on the PC is an internet connection and the VPN Client software.
There is 1 license included for the VPN Client solution with each individually purchased modem, however
additional licenses can be obtained on request (extra charges apply).
The diagram below illustrates the VPN Client connected to a remote TREND’s XTEND.
Field Devices are the foundation of the company’s Smart Structure. They enable efficiency and contribute to the overall value of these Buildings Management System (BMS). If measurement of control at the Field Device Level is not happening, the Buildings Management System is not performing at its most efficient and optimal level.
In HVAC there are lot of Field Devices depending upon the need all are being installed to meet the specific requirement. Slide shows some field devices and yes there are many more addition to this, again depending upon the requirement it is been installed.
Nowadays, Most Energy Management Software have the capability to record and track the real-time energy usage of a building or floor, and to store that information for later analysis. Increasingly though, energy management systems are being used to supplement the energy monitoring and tracking of EMS with functions including weather information, pricing structures, and more sophisticated real-time energy usage data. An Energy Management Software can enable a company to further reduce energy costs by integrating factors such as weather and energy prices into energy management decision making.
Every building owner aims to achieve the cost-effective operation of their building. High synergy effects and vast savings potential frequently go unused. When designing new or modernizing building management systems, cloud solutions and other IT services provided, present a new compelling cost-effective approach.
BMS cloud solutions – the server hardware, BMS application software, data backup, etc. is centralized here and thus efficiently consolidated: secure and central in the cloud.
