Communications (Network Programming)
Once multiple iGrow controllers are wired together (as shown in Figure 4.21), you will need to set up each iGrow
1800’s program settings for proper communications. Note that the most important iGrow1600/1800 in the
network is the one you choose to be the Site Master. The Site Master controls all network communications and
is the only unit that a Weather Station and PC can be connected to.
Site Master

Communications” screen you’ll find several editable fields. By default the text Disabled will be highlighted. Use
the + and - buttons to change this setting to Site Master. Now press the BACK button three times (or until you
see the Main Status screen) to save your changes. That is all that’s necessary to setup the Site Master. Your
Site Master is now ready to communicate with you network and PC.
