Aerobic Septic Dosing Timer Control Panel Dual Alarm


The E5L replaces the discontinued ACP-PD-2A.

Aerobic Treatment Units (ATUs) typically have a couple devices that require electricity. Often times ATUs use their control panel for three main purposes.

The first purpose of a common ATU control panel is to provide power to an air pump. Air needs to be constantly injected into most ATUs, so the air pump needs constant electricity.

The second purpose of a common ATU control panel is to power and control an effluent pump. Systems that use a spray field to discharge their effluent will need a pump to push the water out of the sprinklers. However, running the pump when there is no water in the tank will damage the pump. A float switch is often used with the control panel to ensure the pump only activates when there is water in the system.

Some systems need to control how much water leaves the system per activation of the pump. Controlling the amount of time that the pump can run each time it is activate will limit how much water leaves the system. Dosing timers can be uses to create and on-off cycle for the pump. The timer allows the pump to activate for no longer than what is set by the timer. Then the timer ensures the pump is turned off for the amount of time set by the timer. The pump will then alternate between the on cycle and the off cycle.

The third purpose a common ATU control panel is to alert the homeowner when a problem is detected. If the pump fails, the water within the tank will begin to overfill the system. A high-water alarm is used to alert the homeowner when the water level in the tank is dangerously high. Additionally, air needs to be injected into the system continuously. ATU control panels often have another alarm that triggers when the aerator malfunctions.
