Water feature pumps on timer

I want to put my water feature pumps on a timer.

Here is what I am looking to achieve:

- Control each day of the week separately (or a least weekdays vs weekends)
- Multiple start and stop times during the day
- Easy manual override in case I want the pumps on during a scheduled off time

It would be nice if I could control more than one pump, but multiple units that control one pump would be acceptable as well.

Although I don't think it will work now, but I was originally thinking an irrigation timer feeding some sort of relay might be the ticket. Not sure though.

The pumps will be a 230V 2HP pump (20 amps or less), and a 230V 1HP pump (15 amps or less).

I have tried research myself and I am coming up empty. The timer I have found for water heaters and the like, only control the time of day, not the day of week as well.

Any thoughts on how I can program the pumps to operate the way I want them to.

Welcome to the forums.

Intermatic makes a quality timer and the one in the following link should take care of your needs. You will need to use two of them.

The time clock that PJ linked is an excellent choice and a single unit could operate both of your pumps on independent schedules. It would only be switching one line of your 240 volt source so it would be better to have it operating double pole contactors (or better yet, motor starters) but the two contactors would likely be less expensive than a second time clock.

I have used similar time clocks (I may even have one in my junkpile in the garage) and was completely satisfied. The battery backup is indispensable for maintaining the time and programming in the event of a power failure.

Here is the manufacturer's information along with pdf's of the wiring and programming manual.

Thanks Furd.... I didn't realize I linked to the dual channel timer.
