No, look at what it is wired to in your case it seems to be the stop circuit loop, common is just a common voltage input value, if your system was 24v dc then common maybe the 24v dc + if that is the common value, once the output closes it sends this 24v + to where ever you want, you can also get negatively switch systems so in my example 24v dc - would be common, TBH the term common is very ambiguous and can mean different things in different circuits so don't put a label on it.
Again I am guessing as I have no literature on this controller.
I just wired a panel and have a common 24v+ rail which I tap off to various components, if you buy a standard timer with volts free relay output you get N/O - C - N/C ...you put the power onto the C- common and you switched output(s) on either N/O or N/C or both depending what you want to achieve.
