Their is a way to do this but you have to dedicate one channel to the pump and only use tide mode. If the pump has a max draw- not rated draw because this doesn't factor start up consumption- of 150W and you can give up one channel and use tide mode, you could set that channel to 100% and use the 7094.40 sockets we offer for the 2002 and 4002, however, no adjustmenst to power should be made, they could ruin the pump. Personally I would just reduce the flow through the overflows, save electricity and not worry about the miniscule amount of food that would go through if the flow was slow enough.
