WHM Programming & Start-Up Procedure - Continued
18. Separately enter the desired Start and End time (12:00am to 11:59pm) and then press
ENTER to store each entry.
19. This completes the required entries for the WHM Master. All but two of the required menu
setting will be automatically “pushed” to the WHM Slaves as they are brought on-line. The
options that are not “pushed” to each WHM Slave are:
 Comm Address (in Setup menu)
 WHM
Mode
20. Enter the desired Comm Address and WHM Mode (WHM Slave) at the C-More Control
Panel on each of the WHM Slaves on the network.
21. After the required entries are made at each WHM Slave, check to ensure the REMOTE
LED on the C-More Control Panel for each unit in the WHM network is illuminated. When
illuminated, it indicates that RS485 communications are operating properly.
22. The WHM menu contains two additional menu options which can be set at the WHM
Master. These options are WHM Auto Mstr and WHM Auto Timer. In order to view or
change these two options, the Level 2 Password (6817) must be entered as follows:
a. Press the MENU key on the front panel of the C-More and access the Setup Menu.
b. Scroll to the Password menu option and press the CHANGE key.
c. Enter 6817 and then press the ENTER key to store the password.
d. Press the MENU key on the C-More and scroll back to the WHM Menu.
23. Scroll to the WHM Auto Mstr option. The default value for this option is Off (disabled). If
you wish to enable this option, select Yes and then press the ENTER key to store the
setting.
24. If the WHM Auto Mstr option was set to Yes (enabled) in step 23, proceed to step 25. If
this option remains set to No (disabled), skip step 25 and go to step 26.
25. Scroll to the WHM Auto Timer option. This option is used to select the elapsed time
interval between failure of the WHM Master and switch-over to a new WHM Master. If
desired, this time interval can be changed to any value within the allowable range of 10 to
120 seconds. To alter this setting, press the CHANGE key and enter the desired time
interval and then press ENTER to store the new setting.
26. The WHM Auto Mstr and WHM Auto Timer options will be automatically “pushed” to the
WHM Slaves on the network.
This completes all programming for the WHM.
