Apollo GEM Configuration Options
The system configuration options are found in the installer menus at the end of the set up menu
screens. There are three installer menu pages.
The first installer menu screen sets the basic mode (primary or secondary controller) and the
output mode, i.e. which outputs will be used and their priority. Pairing for wireless systems is
also activated from this menu.
Installer menus 2 and 3 control the configuration options for output 1 and output 2 respectively,
e.g. load power, temperature control method.
Note: If the system will be used for the standard application of diverting excess PV power to a
hot water cylinder using a single water heating element the system can be used straight out of
the box with no configuration.
The configuration options are described in more detail below.
