WattMaster WHP Section 2
Installation and Wiring 2-1
Tips Before Beginning
Installation
Take a few moments to review the following before beginning installation of the
WattMaster WHP System.
• Familiarize yourself with all system components and review all documentation. Pay
special attention to “Cautions” and “Warnings” since these may keep you from
experiencing unnecessary problems.
• Before installing controllers, be sure to tag it with its appropriate location. It is also
best to set the controller address switches before mounting. Use the WHP Address
Worksheet to list all WHP unit locations. This will assist you greatly when setting up
the system.
• Be sure and install all wiring according to local, state, and national electric codes.
• Pay close attention to communication wiring since the most common mistakes are
made in this area. Polarity is the most important rule. Make notes on your wiring
diagrams as to which color wire you will be using on each terminal.
• When in doubt - ask! Contact your local WattMaster distributor if you have any
questions. The only dumb questions are the ones you don’t ask.
• Remember - each electronic device contains only one puff of smoke. If you release it,
you have voided the warranty! So please be careful and pay attention.
