Management of primary and secondary battery
On camper or boat electrical systems there are two batteries: one for the engine/starter and the other for on-board
services when the vehicle is stationary with the engine off.
The battery for services has to be connected to battery 1 (primary) of WRM15 dualB whereas the starter battery has to
be connected on the input of battery 2 (secondary). WRM15 dualB monitors the voltage of both batteries and choose to
load the one or the other in compliance of the logic showed in Pic. 3. If there aren't alarm condition on battery 2 then
will be loaded battery 1 first and in this case the voltage of battery 1 reaches the charging end (Veoc) maintained for a
Tabs period. After that the load for battery 1 is deactivated and is maintained superior than VExitFloat voltage. On the
contrary when the voltage of battery 1 goes below this threshold its load is reactivated.
When the voltage of battery 2 goes below the AlertVBatt2 threshold, independently from the voltage of battery 1,will
be activated the charge on battery 2 up to the attainment of the charging end voltage (Veoc).
Tabs, VExitFloat, AlertVBatt2 parameters are settable through Bluetooth interface.
