Setting up the System
Apollo GEM is a very flexible system with may configuration options to enable use in a wide
variety of situations. 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.
Factory Configuration
• Wired (non-wireless) mode
• Single output on output L1
• Variable power mode for standard 3KW heater
• Temperature control by heater thermostat
• Timer disabled
Setting wireless mode operation
The factory setting is for non-wireless operation.
If wireless operation is required, and the optional wireless sensor transmitter has been
purchased, this is set by moving the wired/wireless jumper, located on the main circuit board to
the right of the display, from the "WIRED" to the "WIRELESS" position.
This must be done with the controller powered off.
When power is applied to the controller the initial start up display will confirm which mode the
system is operating in.
