From version 1.10.0 of the zencontrol commissioning application, there are two ways to change profile in the zencontrol commissioning application.
The first way is to change profile for the whole site, to do this navigate to the site list, then select the site you would like to change profile on. Then select "Change profile" which is under the "Schedules" heading.
This will open a page showing all the profile assigned to any control system on the site. Selecting any of the rows will change all the control systems which have this profile assigned to that profile. The top of the page also shows "returned to scheduled profile, which will put each controller back on its regularly scheduled profile defined in the "Schedules" function.
You can also change profile per control system, to do this navigate to the control system list, and select the control system you wish to change profile on. From the control system dashboard select "change profile", this will show all the assigned profiles on the control system and allow you to switch between them. The top of the page also shows "returned to scheduled profile, which will put the controller back on its regularly scheduled profile defined in the "Schedules" function.
