Richard did bring up 2 nice points. Any time a power failure occurs it waits about 20 minutes before firing the MH bulbs. It has a "soft start" mode for all pumps installed on the timers to prevent impeller breakage.

You can reconfigure the channels and such but I believe 2 or 3 of the outlets are saved for higher amperage equipment as well as "always on" equipment. These spots have designations for things like a sump pump that runs continuously but if you hit a feed button will shut down for your prescribed time period but run at all other times. As well as those features I think you can override the presets and use them for wave makers and or lesser amperage equipment if you choose to. It's just that those channels are saved for that type of equipment if being used.
