After a few seconds with the engine or a charging source running, the device switches on the internal relay to create
the parallel between the two batteries, that will charge them both at the same time. During this stage, the LED indica-
tor is on.
If, during house battery use, the device detects a voltage lower than 10.5 V, the device will immediately disconnect
the battery from the loads. If this happens, the LED indicator turns off. The device reconnects the battery to the loads
if a charging source is connected, such as an alternator, battery charger or solar panel regulator.
The button on the device is used to manually disconnect the house battery from loads and from the starting battery.
The house battery will be reconnected to the loads when the battery voltage has risen to 12.3 V. The house battery
and the starting battery will be parallel when the starting battery voltage is 13.3 V.
