Permissions

• Whomever registers the CON·X·US will be assigned the role of Site Manager. As you register a CON·X·US your user information will be automatically populated in the site manager field.
• The Site Manager is responsible for assigning access to users for each site. As the Site Manager your contact information will be displayed in the “Site Manager” field on the “Service Notification” page of the setup tab (see FIG. 4-1).
• To add a user to a CON·X·US enabled boiler the user will need to create an account (reference the Create Account section on of this manual).
• Once the user that you wish to add has created an account, the Site Manager must enter the e-mail address into the Service Personnel Contact Info section of the Service Notification Menu and click the LINK button.
• This will grant access to the CON·X·US enabled boiler and will be populated on the user’s available devices list (reference Select Devices Screen on of this manual).
• NOTE: The UNLINK button can be used to remove a user. If the Site Manager unlinks themselves, the CON·X·US will need to be re-registered.
• For each service provider, the Site Manager can grant either “View Only” access or “View & Edit” access by clicking one of the boxes to the right of the service provider’s name.
• View Only” access will allow that user to view all information without the ability to make any changes.
• If the Site Manager would like to have a user have “View Only” privileges, but receive alerts, the Site Manager must provide the user with “View & Edit” privileges to allow the user to set up the alerts.
• Once the setup is complete, the Site Manager can then change that user’s access level back to “View Only”. “View & Edit” access will allow that user to view all information and make programming changes.
• The Site Manager and any user with View & Edit privileges can select which alerts they receive. One, all, or none of these notification types can be selected. By selecting “Lockout” the Site Manager or user will receive a text or e-mail about a lockout condition.
• Selecting “Block” will result in an e-mail or text message any time the boiler enters a blocking condition. Blocking conditions are not lockouts, but are conditions such as high outlet temperature, high flue temperature, or high Delta T’s, that result in the boiler limiting itself. Blocking conditions can occur often depending on the operation conditions, but could also indicate a problem. Anti-cycling Blockings are not relayed. Selecting “Parameter Change” will result in an e-mail or text message every time a parameter is changed remotely from CON·X·US or locally through the user interface on the boiler.
• When a boiler with CON·X·US goes into a fault condition an alert will be sent out via e-mail or text message. A text message will be sent if a cell phone number is entered and the cell box is checked (see FIG. 4-4 on).
• Otherwise, the user will receive an e-mail.
• NOTE: Only the Site Manager is able to see all linked personnel. All other personnel will only see the Site Manager.
• By accessing the Setup tab, the Site Manager and any user with “View and Edit” privileges will be able to make changes to all accessible parameters and send the parameters to the boiler.
• To send parameters to the boiler simply click the SEND UPDATE button. The REVERT CHANGES button will retrieve the last saved parameters and re-populate all the screens with those parameters.

How to use the sort function

• By clicking on the ACCOUNT button you will be taken to a list of all the boilers registered to the Account Manager or user.
• You can access any boiler on the list by selecting the desired boiler.
• The sort function can be used to sort the list of boilers by serial number, city, or site name.
• If a boiler is gray, this means it is not communicating with the internet. This could mean that the boiler is powered OFF or that the CON·X·US module is not connected to the internet.
