To help clarify this process, a pump needs to be allowed to run only between the hours of 6:00 and 15:00. Another pump needs to be allowed to run only between the hours of 15:00 and 6:00. Could this be done with a "timeofday" object, keeping in mind that both also have to follow the same neutralzone object of a tank level. If anyone can do this, please explain how in detail. thanks.
