The WHM Menu in each C-More can only be viewed when the Unit Type option in the
Configuration Menu is set to RECON WH. Most of the options in this menu are preset at the
factory and cannot be altered by the user.
A full description of each item appears in section 8.7.
NOTE: some of the WHM menu items appear only if they are enabled, either in the WHM Menu
or by a specific menu item. For example, item 31, WHM Header Temp, does not appear unless
item 30, MB Head Temp En = Enable.
NOTE
In addition to the WHM Menu items listed in Table 8-1, the Setup
Menu contains a Comm Address option which must be entered
for each unit to enable WHM control of the system.
