14.7 230V Triac output
The 230V electrical output can be configured as a pulse
function. For example it can be used to shortly activate an
electrical drain valve.
In this configuration, you can program pulse duration,
day, week or special days you want this to happen.
For example each Sunday at 10h00 for 5 seconds.
