Mode
0
Setting this value to ‘1’ enables preparation mode. All other ‘P—‘menu items are disabled until this value is ‘1’. Note
that control operations may be affected during preparation mode, therefore the cooling unit should be off. Setting this
value back to ‘0’ creates new default values based upon selections in this menu. After default values are established,
the board exits preparation mode and reboots.
P02

VSD
Configuration

This item should only be used to address the VSDs for the unit. The value entered indicates the model of the VSD:

All fans must be the same model to use this parameter. When ENT is pressed, the board will operate and power
contactors for the VSDs and assign ModBus addresses. This procedure may take up to 5minutes to complete.
