Serial ports
for +/- use AWG 20-22 twisted pair shielded
cable
(*): both models are available;(**): confi gurable port J26: see par. 3.2.
Note: In industrial/residential applications with distances greater than 10 m, use
shielded cable with earthed shield.
In domestic applications (EN 55014), regardless of cable length, in versions without
valve driver, the connection cable between controller and terminal and the serial cable
must be shielded and earthed on both sides.

Optional Ultracapacitor module (PCOS0WUC20 or EVD0000UC0). If the controller works constantly at temperatures near the upper limit
Emergency power of 60°C it is recommended to use the external module code EVD0000UC0, if possible placed in the coolest point of the panel. Modules
supply PCOS0WUC20 and EVD0000UC0 can be connected to the same controller at the same time, thereby doubling the energy available for
closing the valves. Important: The module only powers the valve driver and not the controller.
