NOTE 1: Models 2004, 2005, and 2006 are equipped with a two-circuit element feed option.
NOTE 2: Do not make these connections if using the Steffes power line carrier (PLC) control
system to control the heater(s) in the installation. The outdoor sensor is an optional
feature. (Order item #1302026.)
NOTE 3: The Steffes Power Line Carrier (PLC) system is an optional heater control method.
PLC control is available with the use of the Steffes PLC Transmitter or the Steffes
Comfort Control Relay Panel (CCRP). If using the PLC Transmitter and installing
it outdoors, an outdoor sensor for automatic brick core charge regulation is not
required. If installing the PLC Transmitter indoors or if using the PLC control
system built into the CCRP, one external outdoor sensor is required for automatic
brick core charge regulation.
