Safety regulations:
Please read the following information carefully before
installing and operating the controller. When configuring the
controller please change the default settings as illustrated
in section 4.2. This will avoid damage to the solar system
by common problems such as overheating.
Installing the
controller using the default settings without making
any adjustments to the configuration parameters
is likely to result in an overheating condition of the
solar system at some point. Please also note that
changing the system scheme (Arr 1 - 9) will reset all
settings to the defaults. Please ensure that the mounting
is in accordance to local, state and federal regulations.
