1. A control assembly for controlling a liquid management system, said control assembly comprising:

  • A dual relay for controlling a secondary fill pump and a secondary drain pump;

    a level sensor for monitoring a liquid level in a reservoir;

    a fill sensor for monitoring a primary fill pump;

    a drain sensor for monitoring a primary drain pump; and

    a controller being programmed to monitor a time the primary fill pump is operating, a time between a first primary fill pump operation and a second primary fill pump operation, a time between a first primary fill pump operation and a first primary drain pump operation, a time the primary drain pump is operating, a time between a first primary drain pump operation and a second primary drain pump operation, and a time between a first primary drain pump operation and a second primary fill pump operation, said controller also monitoring a liquid level in the reservoir, where the controller is further programmed to operate the secondary fill pump if the time between the first primary fill pump operation and a second primary fill pump operation exceeds a threshold value, said controller operating the secondary drain pump if the time between the first primary drain pump operation and a second primary drain pump operation exceeds a threshold value, wherein the controller is further programmed such that the controller will operate the secondary fill pump if the time between the first primary fill pump operation and a first primary drain pump operation exceeds a threshold value, said controller operating the secondary drain pump if the time between the first primary drain pump operation and a second primary fill pump operation exceeds a threshold value, said controller stopping the secondary fill pump operation if a predetermined high liquid level threshold value for the reservoir is exceeded, and said controller stopping the secondary drain pump if a predetermined low liquid level threshold value for the reservoir is exceeded.
