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.
