2.2.9 Serial port
Use AWG 20-22 twisted pair shielded cable for the +/-
Serial Type/connectors
Serial ZERO pLAN/J10, J11
Serial ONE BMS 1 Serial Card
Serial TWO FieldBus 1 Serial Card • Not integrated on main board
Serial THREE BMS 2 / J25
Serial FOUR FFieldBus 2 / J26 (and
J23 on Large and
Extralarge version)
Note: in industrial/residential environments, for distances > 10 m, shielded cable is required, with the shield connected to earth. In residential environments (EN
55014), irrespective of the cable length, on versions without valve driver, the connection cable between the controller and the terminal and the serial cable must be
shielded and connected to earth at both ends.

optional Ultracapacitor module (PCOS00UC20 or EVD0000UC0). If the controller operates constantly at temperatures near the upper limit of
Emergency power 60°C it's recommended to use the external module EVD0000UC0, where possible located in the coolest point of the panel. The PCOS00UC20
supply and EVD0000UC0 modules can be connected at the same time to the same controller, thus doubling the energy available to close the valves.
Important: The module only powers the valve driver and not the controller.
