Figure 2.7. Example of pLAN connection with the heat pump controller.
Before any configuration make sure that the pLAN connector is disconnected. Failure to disconnect the pLAN cable prior to
configuration may result in installation malfunction and / or damage to the heat pump components.
NOTE
Disconnect the pLAN cable if you need to update the e-Manager or the heat pump software.
In addition to the connection of these devices, the e-manager incorporates a BMS2 PORT that allows communication with external
devices as a slave of a Modbus network. This port is free and its connection is not necessary for the correct functioning of the
system. In case you want to connect an external device to your ecoSMART e-manager, contact Ecoforest technical support before.
