i use a pi-face for my garden watering (controlled via http)
i just today connected a 2nd valve to the first relais (output 0) and found out the relais do not switch the NO contact at all.
it stays always open.
if i trigger the output the relais on the pi-face does move .. and the NC contact will open .. but NO stays open.
is this somethings needed to be set up or is the board just faulty ?
(i never used output 0 before, just the output 1 which works just fine)
