4.6. Bus communication

In order for the e-source manager to function, it is essential that it has pLAN bus communication with the heat pump or with the
cascade of heat pumps for which it works. Install a three-pole, shielded AWG 20-22 cable between the following terminals.
Description
e-source - ecoGEO HP communication bus
e-source - Cascade communication bus
1 The bus cable can be connected at any point of the pLAN network formed by the ecoGEO HP heat pumps and the Supervisor
module

Some other Ecoforest devices also communicate with each other via their pLAN ports. If you want to use the e-source manager in
an installation that has several Ecoforest controllers (e.g. a cascade of several ecoGEO HP heat pumps with an ecoSMART
Supervisor module), this will form part of the pLAN network together with the other controllers.
The pLAN port of the heat pump or of the ecoSMART Supervisor module may already have several cables connected. Connect the
bus cable from the e-source ecoSMART in the same connector together with the other cables. If it is easier, the bus cable can be
connected at any other point of the pLAN network.
