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.
