I have my Pro Logic set to pump on low speed (dual speed Hayward) from 5am-5pm as part of my tweeking my SWG system (FC to high). We are expecting good weather Thurs-Saturday, so kicked on gas heater, controled via Pro Logic. The heater setting is set to call for high speed pump. I would have assumed that would take priority over the off from 5pm-5am, forcing it on high when heat is called for. Guess not as I came home at 6pm, all was off. I guess the delima is that when the pump is in the off state, there is no measurement of the water due to no flow. What is the fix to this other than pump on 24x7 during heat season? I feel as if I am getting into a catch 22 here. Pump on all time = to much FC. Pump off 1/2 time, not reading of water temp, thus not heatability.
