8.7 WHM MENU SETTING DESCRIPTIONS
The required settings for WHM Menu items will vary depending on the number of units
connected to the Modbus network and required setpoint and operating conditions to be
maintained on the network. Set the menu options in accordance with the descriptions provided
in the sections 9.8.1 through 9.8.10 which follow.
NOTE
It is recommended that the WHM Menu settings described in the
following sections be performed first at the WHM Master. This will
simplify the number of required entries since most of the settings
will be “pushed” to the appropriate Slaves.
