View Full Version : Initiating the max-min filling midway through

I keep my RO reservoir under a max-min control using two level sensors. The night before making a water change I wish to fill up the reservoir to have enough RO water ready for the change. So far I have done this by physically pressing down the lower level for a few seconds and thereby initiate the fill-procedure of the reservoir. But surely there must be a way to program this using a timer, a maintenance function or logic programming? The upper sensor for the maximum water level must, however, always have precedence to all other activities to avoid overflow of the RO reservoir.

Any thoughts on how to solve this?
