Hello: I find many post regarding heater not turning on ..... but in my case its turning on all the time. My heater should only turn on when the pool equipment turns on and the water is cooler then the setting... but no it will turn on every day when the equipment goes on. So I was thinking can it be the Automatic ignition system, electronic thermostat circuit board or my last thought was digital display temperature controller board. Any one have any thoughts or knowledge of what these parts do so that i can get a starting point..... Thank you in advanced.
