Fig. 2.6: Powerline communication between devices
The main purpose of electric wiring in a building is to supply power to various appli-
ances. Such installations are not optimized for the transmission of high-frequency
(100 kHz range) signals. To obtain interference-free communication in this frequency
range, the transmission line between the Sunny Boy Control and the other devices
must be carefully selected.
The transmission line should meet the following conditions.
•
Use only one phase
•
Be as short as possible
Make sure that all devices to be monitored by the Sunny Boy Control are connected
to the same phase, preferably even to the same line. In other words, make sure that
