Switching between office hours and closed hours with feature codes

Ive setup a small Freepbx environment with 5 phones. Then configured time conditions and use them for the inbound route. I made 2 versions: working hours and closed hours.
Every now and then Im leaving my office and want to manually switch to closed hours.
When I try to do this with the proper feature code (*271 is open and *272 is closed)
For example: when time condition Open is active , Im trying to activate time condittion Closed with *272 , and this is not working ..
Is this possible or am I thinking wrong ?
And if Im thinking wrong , what is the proper way to do this ?
Thanks in advance,
Harry
