Thank you very much for buying OLYS product ,Please read
thoroughly before using the prouuct
Description of Functions
1.The controller is ideal for use with motorhomes, caravans, boats or anywhere there are two independent batteries for instance
a starter battery and a leisure battery.
2.Optional LCD Remote meter, you can monitor the charging parameter visual.
3.Automatic recognize 12V or 24V system.
4.The Charging percentages for each battery can be set manually if required.
5.PWM charging, high precision temperature compensation
6.Over charging, short-circuit, reverse polarity & reverse current to PV Protection

NOTE:
in the normal charging status, the controller will divide the
charge equally,when battery 1# is fully charged, more charge
current will be diverted to battery 2#, and then automatically
return to charging battery 1# when its voltage is low.when the
controller detects there is only battery 1#,all the charging will
go to battery 1# automatically
