The PLC system is a highly accurate and reliable method of control. Communications between the transmitter and a correlating receiver occur on regular basis. It may take up to seven (7) minutes for the transmitter to establish initial communication, depending on the speed of the channel selected and the noise level on the electrical systems. Subsequent communications will occur more rapidly. In the 1000 and/or 2000 series heater, the lower right indicator light on their face plate will illuminate green continuously once the heater begins to retrieve good signal. In the mini receiver device, the red indicator light on its circuit board will illuminate continuously once it is receiving complete information. In the 2100, 3100, 4100, 5100, 6100, 7100, 8100, and 9100 series systems, access the Help Menu to verify power line carrier communication.
NOTE: If NOT utilizing the automatic charge control feature of the CCRP, a 4300 ohm resistor must be placed between the two OS terminals to prevent the 2100, 3100, 4100, or 5100, 6100, 7100, 8100, and 9100 series Series heating system(s) from displaying Error 6 (Er 06).
