Each Energy Bar outlet can be configured to be either in an off or on state if the power were to fail and then come back on or if there was a communication failure with the Apex base unit. This means that if, for instance, your heater was on when the power went off, you could have it programmed to be off until control was reestablished with the Apex base unit. Or, as another example, you could program your main return pump to always be in the on position in case of failure.
This feature is very important as many other controllers on the market may leave the outlet in its last position or possibly default all of the outlets to off or on. This is even true if they simply lose communication with their base unit due to a system failure, software bug, communication issue, lightning strike, etc. Not good. Imagine if you were away from home and a storm took out your Apex – the Energy Bar would just fall back to the Failsafe state you had programmed for such an incident. No worries.
One additional advanced feature is that when you use an additional Energy Bar on a UPS (uninterruptible power supply) you can have key lifesaving devices (low power power heads and bubblers) on there that will automatically go into their Failsafe State once power failure is detected. This can keep your tank alive and healthy for hours on a good UPS until the power comes back online. This will run completely unattended and is ideal to give you peace of mind when you are away from home whether out for the evening or on a two-week cruise!
It is easy to see the importance of this one small feature that differentiates the Neptune Systems Energy Bars from the rest and how once again Neptune Systems is looking out for every possible way for you to avoid catastrophe in your aquarium.
