48/50PG and PM

Accessory Navigator Display

The accessory hand-held Navigator display can be used with the 48/50PG and 48/50PM units. (See Fig. 2.) The Navigator display operates the same way as the Scrolling Marquee device. The Navigator display is plugged into the LEN (local equipment network) port on either TB1/TB2 or the J3 port on the ECB (economizer control board).

Fig. 2 − Accessory Navigator Display

Operation

All units are shipped from the factory with the Scrolling Marquee display, which is located in the main control box. (See Fig. 1.) In addition, the ComfortLink control also supports the use of the handheld Navigator display.

Both displays provide the user with an interface to the ComfortLink control system. The displays have up and down arrow keys, an ESCAPE key and an ENTER key. These keys are used to navigate through the different levels of the display structure. The Navigator display and the Scrolling Marquee operate in the same manner, except that the Navigator display has multiple lines of display and the Scrolling Marquee has a single line. All further discussions and examples in this document will be based on the Scrolling Marquee display. See Table 2 for the menu structure.

The four keys are used to navigate through the display structure, which is organized in a tiered mode structure. If the buttons have not been used for a period, the display will default to the AUTO VIEW display category as shown under the RUN STATUS category. To show the top-level display, press the ESCAPE key until a blank display is shown. Then use the up and down arrow keys to scroll through the top-level categories. These are listed in Appendix A and will be indicated on the Scrolling Marquee by the LED next to each mode listed on the face of the display.

When a specific mode or sub-mode is located, push the ENTER key to enter the mode. Depending on the mode, there may be additional tiers. Continue to use the up and down keys and the ENTER keys until the desired display item is found. At any time, the user can move back a mode level by pressing the ESCAPE key. Once an item has been selected the display will flash showing the item, followed by the item value and then followed by the item units (if any).

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 indicating 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 password 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.

There are some points that can be forced from the Scrolling Marquee or the Navigator. If the user needs to force a variable, follow the same process as when editing a configuration parameter. A forced variable, regardless where the force has come from will be displayed with a blinking “.” on a Scrolling Marquee and a blinking “f” on a Navigator following its value. For example, if economizer commanded position (EC.CP) is forced, the Navigator display shows “80f”, where the “f” is blinking to signify a force on the point. The Scrolling Marquee display shows “80.” Where the “.” is blinking to signify a force on the point. Remove the force by selecting the point that is forced with the key ENTER and then pressing the up and down arrow 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 Pilott and Touch Pilot Devices

The System Pilot device (33PILOT-01) and Touch Pilot device (33CNTPILOT) can be used as CCN communication user−interfaces. These devices can be put on the CCN bus and addressed to communicate with any other device on the network. Unlike the Scrolling Marquee and Navigator, these pilots read the unit’s CCN tables and its CCN points can be monitored, forced, or configured. The Pilot devices can be used to install and commission a 3V zoning system, linkage compatible air source, universal controller, and all other devices operating on the Carrier communicating network.

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 device 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/devices. The variable names used for the CCN tables and the Scrolling Marquee menus may be different and more items may be displayed in the CCN tables. Details on the CCN tables are included with the local display menus in Appendix A. Appendix A is structured towards the organization of the local display (Scrolling Marquee) menus. Because of the variety of CCN programs and devices, the CCN tables, sub−tables, and points are referenced within that organization.
