8.9 WHM PROGRAMMING & START-UP
Prior to programming the required WHM Menu options into the WHM Master and Slaves, all
required hardware installation and network wiring must be completed. In addition, the required
menu entries to be entered must be determined based on the descriptions in the previous
sections.
AERCO recommends that the WHM Master be set up first. By doing so, the Master will “push”
most of the required menu entries to each WHM Slave as each unit is brought on-line. The
following steps assume that the WHM Master and Slaves will be consecutively numbered,
starting at 1 (WHM Master). Proceed as follows starting at the unit which has previously been
determined to be the WHM Master:
