We just had our heater and pump timers installed and rhe heater timer is already screwed up, it won't hold the correct time. We also noticed the pump timer kept shutting off ot not working. I added CYA to my pool yesterday and used the manual override to make sure the pump ran for 24 hours. I woke up this morning and the pump is off, the manual override switch is in the off position. Does anyone have any ideas?
