Hi. I have a duoclear 60 pool chlorinator. My problem is that the timer works to turn off the chlorinator and pump at night. However, in the morning it turns the pump on but not the chlorinator. I can manually turn the chlorinator on and it works fine and will again turn off with the timer at night. I tried running the chlorinator for 3 days straight to see if the battery needed to be recharged. This did not resolve the problem. Is it an issue with the board?
