I have a Intermatic PE153 digital timer that has three loads. Issue is that I just added a heater to my system (Sta-Rite 400K BTU). I assume this means I would need to upgrade my timer to a 4-load - Hi pump/lo pump/swg/heater. I can't locate a time that has 4 loads that will ensure hi pump is running before kicking off swg or heater. Does this mean I need to upgrade to a control center now? If so, it the PE153 no longer needed? Any advisement on a solution?
