    Power outage

    Does communication from the aquabus and from the 0-10v ports work when the eb832 has no power, but the head unit and the pumps that communicating through 0-10v or aquabus have power?

    I want to plug my apex head unit, tunze pumps and a return pump into a battery back up for power outages, but I feel like the eb832 would use unnecessary power in an outage. Is this possible?

    Yes. As long as the aquabus is getting power, communication is possible. Of course, if the eb832 does not have power then none of the equipment will be able to run.

    You could put the EB832 on the ups, then use the aux power port of the apex to detect a loss of mains power. This would allow you to control the individual outlets as desired during an outage. I use two EB8s, one on ups that has critical equipment, the other on mains for non-critical. I detect power loss from the one on mains, then alter the behavior of the critical equipment to reduce power usage to extend the battery life.

    There are several threads here on the board on different power outage strategies.

    So, the apex head unit cannot power the aquabus with the 12v power supply?

    It can, but it's usually better to hook the UPS up to the energy bar (assuming its rated for the loads on your energy bar) and shut off anything you don't want on when a power loss is detected in the AUX port.
