I am trying to replicate a rain storm for a wetland mesocosm experiment. I have a 1/2 hp AC transfer pump for pumping water through large stock tanks. In order to replicate a rain storm, my idea is to piggy back the pump on a timer (with a float switch to the inflow doesn't run dry). A vertical float switch would need to be used so an not to over fill the first tank.

I would like to not only control time of flow but also intensity.

Will this timer with it's ability to "alternately cycle 2 different loads" be able to replicate at least a two step cycle of:

Off 5 mins

Half power 5 mins

Full power 5 mins

Half power 5 mins

or am I misunderstanding what "It can alternately cycle 2 different loads" means?
