Using WF2CC to enable or disable charging from a Keba EVSA (car charger)

I would like to use a WF2CC to close or open a circuit to control charging from my Electric Vehicle charger.  I don't need to provide power on the relay circuit when it's closed ... the Keba unit uses low voltage to sense the state of the contact

I think I understand how to set up the WF2CC and send it commands to open or close a contact.   What I need to understand is whether, once I send a command to close the contact, does it stay in that state until another command is sent to tell it to open?

The reason I ask is that we have time of day charging for electricity, so I want to enable changing from 7pm to 7am weekdays and all day on weekends/holidays.   I can easily set up a schedule using my existing cron table on linux.
