Installation & Maintenance is an app used to set up/modify/check the devices in your system and set the general system settings.
The Installation & Maintenance app has two tabs: Equipment and Settings.
The Equipment tab lists information about the equipment connected at the selected site. The Settings tab shows all of the settings that can be changed at the selected site. Note that when "All sites" is selected, the Settings tab will not show any settings. To see valid settings, first select a site.
