Auto mode schedules dosing specific to what additive or solution is being dosed. This mode utilizes standard dosing practices and known water parameter changes in a reef tank based on light cycle and biological activity. The Versa does not determine dosing volume, that requires testing and tuning. It will however, schedule dosing based on the salt or additive selected.
Continuous mode sets a dosing rate (volume/min) that runs when the pump is powered. Continuous mode is an always-operating dosing mode and needs to be controlled by external means (controller, timer, float switch, etc.).
Manual Mode allows the user to create a program specifying dosing volumes and or durations. The Versas variable operational capability allows volume dosing to be carried out a specified rate or over a specified time period. Up to 30 discrete dosing events can be created per pump in a 24hr period. The Catch-Up feature allows the Versa to correct a dosing difference if the pump is shut down or is interrupted during its daily program. Safe-guards help protects against some potential dosing issues.
