Comfort Control Relay Panel (CCRP)
GENERAL OPERATION
The Steffes Comfort Control Relay Panel (CCRP) is a device used for the
control of electrical loads such as ETS heaters, water heaters, baseboards,
electric furnaces, dryers, dishwashers, hot tubs, ceiling cable, etc. The
CCRP can control up to nine (9) electrical circuits using its internal, board
mounted relays. In addition, its built-in Power Line Carrier (PLC) Trans-
mitter provides communication to and control of an unlimited number of
Steffes microprocessor based heating systems, as well as any other
devices incorporating the Steffes PLC Receiver through existing power
circuits.
Upon receipt of the utility control signal the CCRP will actuate its internal
relays to control the devices wired into them. The CCRP is capable of
accepting up to six (6) separate utility control signals. This feature works
well in areas where the power company has multiple rate strategies.
If utilizing the PLC transmitter feature in the relay panel, it will send the utility control signal through the existing
electrical circuits. All Steffes microprocessor based heating systems and other controllable devices incorporating
the Steffes PLC Receiver that are served power by the same power company distribution transformer will
receive this signal and respond accordingly. The PLC control feature allows for peak control of devices without
having to do direct wiring. This feature can reduce installation costs significantly, especially in multiple unit
installations and projects such as housing subdivisions, hotels, motels, apartments, condo’s, etc.
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 Corporation does not guarantee effective communication of the PLC system in all applications and is not
responsible for any communication issues outside normal operating malfunctions.
