The Steffes Power Line Carrier (PLC) control system has the ability to communicate with the system through the existing electrical circuits in the structure. With the power line carrier option, direct wired low voltage connections from the power company's peak signaling switch connect directly to the transmitting device. The switch signals peak control times to the transmitter, the transmitter sends the signals to the Comfort Plus system, which receives this information and responds accordingly.
In addition to providing peak control signals, the transmitter also provides outdoor temperature information for automatic charge control, room temperature set back, and anticipated peak utility control signals (if applicable).
The PLC system is optional and must be ordered separately. If utilizing a PLC system, an Owner's and Installer's manual will accompany the transmitting device. Refer to this manual for information on the installation and operation of the power line carrier control system.
