The Steffes Power Line Carrier (PLC) Transmitter is a device used for communicating information through the local electric circuits to an unlimited number of Steffes microprocessor based heating systems (1000, 2000, 2100, 3100, 4100, and 5100 Series) and other controllable devices incorporating the Steffes PLC receiver. A receiver is built into Steffes microprocessor based heating systems, so the transmitter can communicate directly with the equipment without the cost of additional controls or electrical wiring. Therefore, overall installation costs of an ETS system can be significantly reduced, especially in multiple unit installations and projects such as hotels, motels, apartments, condos, etc.
The transmitter must be wired into the line voltage power serving the installation. The transmitter continuously sends information through the local electric circuits. This information is received by the Steffes heating equipment and other controllable devices with a correlating receiver, provided they are on the same power company distribution transformer as the transmitter.
PLC Communication is very reliable in most applications but can be affected and hindered by connection method used, electrical layout of the application, operation of other equipment in the same electric system, dirty power, etc. Steffes does not guarantee effective communication of the PLC system in all applications and is not responsible for any communication issues outside normal operating malfunctions.
