The Tunze RO Water Controller is an essential component for managing your reverse osmosis (RO) water production system in both saltwater and freshwater aquariums. It uses two float switches to control the electronic valve, ensuring that your fresh water storage container fills up only as needed until it reaches a predetermined level set by the second switch, after which the valve closes automatically. This controller also features an overflow timer backup that can be programmed for either 12 or 24 hours, activating an alarm if the float switch does not trigger within this period to prevent overfilling and potential damage.
