IMPORTANT The CPU reset button deletes the application program in the CPU (stored in RAM). If the reset button is pushed when the CPU contains an application, the device must be re-downloaded. Step 3. Commissioning The Zone Manager CPU can be commissioned (given a C-Bus address) using an operator terminal such as the XI58 (on the PC that has the XI584 software and/or CARE installed). This operation is performed the same as for other C-Bus controllers. The following steps describe the most common procedure using the PC to commission the CPU just before downloading from the XI584. As for other C-Bus controllers, commissioning is required only after an initial power-up or if the CPU reset button was pushed. The following steps assume the Zone Manager Plant and Controller are configured in CARE (see Data File Setup section):. Connect the PC COM port to the Zone Manager B-port using the XW565 (or XW566) prefabricated cable.. Start XI584. Sign on and run XI58. Assign the controller number using the procedure for C-Bus devices (see the XI584 User's Guide, form 74-3555). 3. Select Continue again, and select Request Download. The operator terminal should then display. Please Execute Download. 4. Select Utilities and drop down to the item File Transfer/Download. Click on All and initiate the Download. Commissioning is complete. The B-port Transmit and B-port Receive LEDs on the Zone Manager should start blinking rapidly, indicating communication between the PC and the Zone Manager. Any Download errors or connecting problems appear in the Download Results list box. A loss of communication with the B-port during downloading generates an alarm after three minutes. Press Enter and try again to download. If there is trouble establishing communication between the PC and the Zone Manager, check the following items: XW565 cable connections. XW565 cable connection is to the same PC COM port as selected in the CARE Download System Settings menu. IMPORTANT Carefully watch all C-Bus alarm activity following a download. Follow up as necessary on all problem alarms. Fig. 8. Connect Operating Device. Close Cover Put the device cover back on (See Fig. 9). DATA FILE SETUP Fig. 9. Close Cover. M8558 M8559 Generate the CARE data file for the Zone Manager/RIO/Excel 0 VAV controllers. This data file has a mix of hardware points for the necessary inputs and outputs to control fans, dampers and other equipment. In addition to the inputs and outputs, a custom control program is written to control the outputs per the sequence. It also resets the program once the data from the operator interface indicates a normal condition for the new dedicated smoke control equipment. Wire conditions must be programmed to provide annunciation of trouble conditions. Also required for a dedicated application is a weekly time program to test control points, fans and dampers by exercising the equipment and verifying feedback automatically during low building activity periods. 95-7509 9

The internal memory in this series of controllers is supported by a Varta 67 CR / AA 3V lithium battery (not rechargeable). When the battery requires replacement, a low battery condition is indicated on the controller and sent to the MMI and central monitoring station. Replace when needed with the same battery type. For service, contact your local Honeywell Home & Building Control office as listed in the phone book, or contact a regional office as shown at the end of this document. 5 95-7509 9
