Carrier 48/50AJ specifications System Pilot User Interface

Items in the Configuration and Service Test modes are password protected. The display will flash PASS and WORD when required. Use the ENTER and arrow keys to enter the four digits of the password. The default password is 1111.

Pressing the ESCAPE and ENTER keys simultaneously will scroll an expanded text description across the display indi- cating the full meaning of each display point. Pressing the ESCAPE and ENTER keys when the display is blank (MODE LED level) will return the display to its default menu of rotating AUTO VIEW display items. In addition, the pass- word will need to be entered again before changes can be made.

Changing item values or testing outputs is accomplished in the same manner. Locate and display the desired item. If the display is in rotating auto-view, press the ENTER key to stop the display at the desired item. Press the ENTER key again so that the item value flashes. Use the arrow keys to change the value of state of an item and press the ENTER key to accept it. Press the ESCAPE key and the item, value or units display will resume. Repeat the process as required for other items.

If the user needs to force a variable, follow the same process as when editing a configuration parameter. A forced variable will be displayed with a blinking “f” following its value. For example, if supply fan requested (FAN.F) is forced, the display shows “YESf”, where the “f” is blinking to signify a force on the point. Remove the force by selecting the point that is forced

with the ENTER key and then pressing the and ar- row keys simultaneously.

Depending on the unit model, factory-installed options and field-installed accessories, some of the items in the various Mode categories may not apply.

System Pilot™ Interface — The System Pilot (33PILOT-01) device is a component of Carrier’s 3V™ system and serves as a user-interface and configuration tool for all Car- rier communicating devices. The System Pilot device can be used to install and commission a 3V zoning system, linkage compatible air source, universal controller, and all other devic- es operating on the CCN system.

Additionally, the System Pilot device can serve as a wall-mounted temperature sensor for space temperature measurement. The occupant can use the System Pilot device to change set points. A security feature is provided to limit access of features for unauthorized users. See Fig. 3 for System Pilot details.

CCN Tables and Display — In addition to the unit- mounted scrolling marquee display, the user can also access the same information through the CCN tables by using the Service Tool or other CCN programs. Details on the CCN tables are summarized in Appendix B. The variable names used for the CCN tables and the scrolling marquee tables may be different and more items are displayed in the CCN tables. As a refer- ence, the CCN variable names are included in the scrolling marquee tables and the scrolling marquee names are included in the local display tables in Appendix B.

GENERICS STATUS DISPLAY TABLE — The GENERICS points table allows the service/installer the ability to create a custom table in which up to 20 points from the 5 CCN categories (Points, Config, Service-Config, Set Point, and Maintenance) may be collected and displayed.

In the Service-Config table section, there is a table named “generics”. This table contains placeholders for up to 20 CCN point names and allows the user to decide which points are dis- played in the GENERICS points table under the local display. Each one of these placeholders allows the input of an 8-character ASCII string. Using a CCN interface, enter the Edit mode for the Service-Config table “generics” and enter the CCN name for each point to be displayed in the custom points table in the order they will be displayed. When done entering point names, down- load the table to the rooftop unit control.

IMPORTANT: The computer system software (ComfortVIEW™, Service Tool, etc.) that is used to interact with CCN controls always saves a template of items it considers as static (e.g., limits, units, forcibil- ity, 24-character text strings, and point names) after the software uploads the tables from a control. There- after, the software is only concerned with run time data like value and hardware/force status. With this in mind, it is important that anytime a change is made to the Service-Config table “generics” (which in turn changes the points contained in the GENERICS point table), that a complete new upload be performed. This requires that any previous table database be completely removed first. Failure to do this will not allow the user to display the new points that have been created and the CCN interface will have a different table database than the unit control.
