Maximum Number of Zones

[HereComesTheRain]

From the valve specs it looks like you have some valves of US origin (60Hz) and some of UK/European origin (50Hz).

Assuming all the valves are 24V, the maximum current draw would be the highest inrush current times the number of valves that are switched on at the same time. Five valves at 370mA * 5 = 1850mA or nearly 2A. The adapter should have at least an additional 10% capacity so 2.2A minimum.

Oops. They are all US (60Hz). I was a little fast with the copy & paste.  

What does Station delay: do?  Is that just a delay of start of energizing a relay/valve when you have scheduled a series of events?  Could that be used to safely open multiple valves or would I need to code something to make that happen.

Would be neat to have a GROUPS feature.  A user could group a set of valves and then schedule that GROUP to come on and off.  The GROUPS feature could have a Station Delay to open the valves in the GROUP in sequence.  

Will be much happier when I get to the software side of things.  Digging in the dirt, being eaten alive by flies and having to purchase odds and ends at extremely inflated prices is getting old.

Thanks again for all your effort and hard work on this project.
