Connecting Communication Cables to Mini-Plug (REU-E & REU-VCM)
CAUTION
Installation MUST
DO NOT attempt to connect water controller cables to the mini-plug when it is plugged into the
components may occur.
Water controllers are connected to the PCB via a dedicated pre-wired mini-plug (supplied).
Use the supplied electrical cable connectors to terminate the water controller wires to those of the mini-plug. The
existing spade connectors of the communication cables will need to be removed prior to termination. Controllers
are not polarity sensitive, however to avoid confusion it is recommended that like coloured wires be terminated
together.
