Objectives • The purpose of this class • Identify the Components of the IVU system • Connect to & Navigate the IVU • Make changes in the IVU • Properly setting up schedules and schedule groups • View alarms & set up notifications • Access Historical Data & Reports • Managing your users • Provide you with the confidence to approach the IVU and take control of your BAS.
Introduction to IVU • There are Four different types of IVU systems • CCN Standard (Most common) • CCN Plus • IVU Open (BacNet based protocol) • IVU Pro (Carrier Proprietary, BacNet based protocol)
Components of the IVU The IVU Router/link module
CCN Types STANDARD PLUS • Version 4.0 & 4.2 • Connects to the CCN bus via USB dongle • Connects up to 120 devices (memory based, not actual physical count) • Auto generated graphics (Carrier CCN devices) • Auto discovery of Carrier CCN devices • Uses a Router to connect to the CCN Network • Link module allows for integration to LON/N2/BacNet devices • Allows up to 750 devices to be on the IVU (120) per router • Auto generated graphics (Carrier CCN devices) • Auto discovery of Carrier CCN devices
Open Types STANDARD PLUS • Connects to BacNet MSTP using a USB dongle • Connects up to 120 devices (memory based, not actual physical count) • Auto generated graphics (Carrier Open devices) • Auto discovery of Carrier Open devices • Connects to BacNet MSTP using a USB dongle • Does not currently communicate with CCN • Link module allows for integration to LON/N2/BacNet devices • Allows up to 720 devices to be on the IVU (120) per router • Auto generated graphics (Carrier Open devices) • Auto discovery of Carrier Open devices
IVU Pro • Server based that is installed on a PC • Communicates via BacNet (over IP or MSTP through a Link module) • Does communicate with CCN via Link module • Link module allows for integration to LON/N2/BacNet devices • Provides an unlimited amount of devices to be installed on the IVU, you are only limited by the PC hard drive it is installed on
IVU Network The CCN IVU sits on the CCN Network just like any other controller. It has a CCN address just like any other CCN device. Default at 0,234 and 0,235. The IVU also has the capability to sit on an IP Network and has an IP address that matches the IP scheme of the network. DHCP is supported, but not recommended. The router and link modules (plus versions) also sits on the IP Network as well as the controls network (CCN/Bacnet MSTP/Bacnet IP/Lon) and collects the data to send to the IVU itself The IVU can be left as a stand alone network and not be connected to the buildings network if necessary. RTU1 VAV1 VAV2 PIU1 PIU2 PIU3 Router/Link CCN/BacNet/Lon/N2 WWW IP network IVU CAT5
Connecting to the IVU • To connect to an IVU your computer must be a part of the network that the IVU resides on. • If the IVU is on a buildings network, then any computer that is connected to that network can connect to the IVU using Internet Explorer by simply typing in the IP address of the IVU (i.e. 192.168.1.12) • You may also use a DNS which allows you to name the IVU. Default is IVU. • If your computer is not on the network, you must connect it to the network first, then you can browse to the IVU IP address
Changing Your IP settings If you computer is not on the same network as the IVU, and you do not have permission to join the network, you may direct connect to the IVU. To Direct connect to the IVU, you must connect a CAT5 cable from your PC to the Ethernet jack on the back of the IVU. If you know the IP address of the IVU then all you have to do is change your computer’s IP settings to match the IVU IP settings. If you do not know the IVU IP settings, then you will need to connect a monitor to the IVU and restart it to look up the IVU IP address.
Getting Started! Once you get connected you will be directed to the login screen. Type in your credentials and you are ready to go. User names and passwords are case sensitive so please remember your password. In the event you forget your password the IVU will allow you three attempts to log in. In the event of three failed attempts you will be locked out of the IVU for 30 minutes. An Administrator has the capability of logging in and resetting your password or releasing the lockout.
Navigating the IVU The IVU uses a Hierarchy navigation much like you see in Windows explorer. The Navigation tree on the left hand side of the screen can be expanded and collapsed to view different sections of the IVU. It holds Parent nodes (folders) which share properties with it’s child nodes (subfolders). Anything applied to a parent will automatically be applied to all of its children! The building level is the highest Node and will affect everything set up in the IVU.
Other Ways to Navigate The IVU allows several different ways to navigate the system. There are Tabs At the head of the screen which allow you to view a Graphic, Schedules, Alarms Trends, and Reports. You can use the navigation tree as explained previously. Or depending on the installer, there may be several hot links that will take your Directly to a specific piece of equipment. Such as the color bubles on a floor plan.
Making Changes in the IVU When a Carrier CCN device is scanned into the IVU it automatically recognizes the unit type, version, and configuration settings. Based on these settings the IVU will build a graphic for the device being added to the system. The Graphic will allow you to view and change points based on your access level.
What can be in a graphic? Auto Generated Things to watch for • Fan Start/Stop • Fan Status • Temperatures • Damper Positions • Heating and Cooling Stages • Occupancy status • Enthalpy • Just because a fan is turning in the graphic doesn’t mean it is turning in real life! • On custom graphics did the point get mapped to the right unit? • On Auto graphics is the point looking at an enable or a status???
Adjusting Set points On most types of equipment you can adjust the set points right from The graphic. The dynamic color slide bar gives you the option of Adjusting the heating and cooling set points by typing them into their Respective fields or by sliding the color bars using your mouse. Notice that the top color bar with the green index is the occupied set points, and the lower color bar with the grey as the index is the unoccupied set points.
Once you make your changes you must select OK. This button will appear once you click in any adjustable field inside the IVU. If you clicked on an adjustable field by accident, simply click cancel. The IVU will not allow you to navigate until you select one of these two options.
Forcing a point You can force some points in the IVU, such as Temperatures, Fan start/stops, and damper positions. Whether or not you have this capability will depend on your user level. If viewing a custom graphic it will depend on your installer whether or not you can force points. You force a point by right clicking it and selecting Microblock properties.
This is the Microblock property page. From here you can select force check box and enter the desired information you would like to change it to. Don’t forget to click OK or Apply to effectively download your changes.
What’s the difference??? No force forced
Scheduling in the IVU The scheduling tab on any piece of equipment will show you the current schedules in that unit. Notice the color codes and priority key at the bottom. It is possible to have multiple schedules commanding the same piece of equipment. The white areas shown in the graphic represent the effective schedule for this unit. It is important to remember the Effective Occupancy schedule can be made up of more than one schedule.
Scheduling in the IVU Notice now there is a yellow bar above the white bar. If we check our color key below, we will see that the yellow bar represents the Normal (Occupied) schedule. You can display this at any time by simply clicking on the white effective bar in the graphic. The name will be displayed beside each schedule that is in the graphic. How do we make and adjust schedules???
Making and Adjusting Schedules Equipment/floor level Scheduling groups • You can create schedules at any level inside the Hierarchy tree. • You can add them at a floor plan level which will be applied to every child in that level • Or you can make a single schedule for a single unit • Scheduling Groups simplifies the process of the Hierarchy • You may add members from any level in the tree • You can easily sort and organize your scheduling. KISS method! Be careful when creating schedules in a VVT system!!!
Schedules Tab View Configure
Adding a New Schedule Priority Type • Normal – regular occupied schedule • Holliday – sets the schedule to be UNOCCUPIED! • Override – sets the schedule to Occupied • The Holliday and Override schedules will take Priority over a Normal Schedule • Weekly – Mon thru Sun Time schedule • Date – a single date schedule • Date Range – a set of dates that run congruently • Date List – a set of dates that do not run congruently
Alarms in the IVU In the top right corner of the screen there is an exclamation point. In this picture it is red. When the icon is red, there is an alarm somewhere in the system. By clicking on the icon you will be directed to the building level alarms page. The re is a small table that will appear at the top right of the page that displays the number of Need to Return, Need to Acknowledge, and Closed Alarms in the system. Beside that is a navigation button that will allow you to scroll through the list of alarms one at a time or from top to bottom from the first to the last alarm.
Alarms in the IVU Remember the Hierarchy of the IVU? Below is an example of a unit specific alarm page. Notice that we only see the alarms that are specific to the device that is selected in the Navigation tree on the left hand side of the screen. This allows for easy organization of alarms for viewing and troubleshooting.
Email Alarm Notifications The IVU has the capability out of the box to be able to send email notifications. All it requires is an email account to be assigned to it just as if it were another employee on the network You can select any range of alarms to send out, so your IT dept gets the alarms on CRAC units, and your Maintenance Engineer get the RTU and high temp alarms but not the CRAC unit alarms. An optional software solution may be installed called Alarm Popup. This will allow alarms to be sent over the Network and be displayed in a pop up window on any pc that the software is installed on.
Trends in the IVU It is possible to look at historical data using a trend graphic. Several different trends come setup default in the IVU. Such as Space Temperature and supply air temperature. As seen here you may select more than one point to be in your trend graphic at a time. You may also right click on the graphic and export it into an excel file. (copy the date and paste it ) The trend graphic is dynamic as well and allows you to highlight and select specific times and areas in the graphic itself with your mouse.
Reports in the IVU There are several different reports you can run in the IVU as well Alarms – Active alarms Alarm sources Alarm actions Schedules - Instances Effective schedules Equipment – Points list Network IO settings Trend Usage Audit Log – Transactional history of the IVU You can export any of these reports after they have been run in a pdf or excel format
System Options The system options Page allows for several different configuration changes in the IVU server itself. Your user level will determine what access you have to these screens and functions. My settings – holds user specific settings that can be adjusted by the user at any time. Operators allows you to add/remove users, as well as reset passwords and reconfigure user levels and access General – allows you to adjust the time in the IVU and change the Network IP settings.
Adding a New User In the System Options Page under the Operators tab you can add, edit, or delete users and adjust their settings. Please note that the Name is different than the Login Name. You can create a password for the user upon setup, or you can force the user to change their password at login. Roles determines the user access the person will have. Standard users are recommended for persons that are not familiar with the IVU and are learning to navigate the system.
Questions and comments? The only stupid question is the question not asked
