Thread: Min. temp. difference between Solar and Water

    Min. temp. difference between Solar and Water


    I just installed a set of solar pannels. The system is controlled by the Aqua-Logic pannel and I use a Heliotrope Pro-verter valve.
    When I came back from work today, I noticed the valve was off (physically but also in the Aqua-Logic system display) even though the water temperature was a couple degrees below the solar sensor reading.

    So here's the question: Is there a minimum temperature difference (between solar and water sensors) in order for Aqua-Logic to activate the solar heating system?

    Thank you,

    Yes, the controller is looking for at least a couple of degrees temersture difference. At very small differences you might get some tiny amount of heat, but not enough for it to be worth it.
