Dew Point Control for radiant cooling

I'm doing a geothermal w/ radiant cooling. I need a control to keep the radiant cooling above the dew point to prevent condensation from forming? Who make a dew point control for this?

    Google: Weiss Instruments.

    Their are others.
    If you need application help

    Try Kele Associates in TN. They sell controls and can give you some help

    The Weiss control looks simple and should work

    I think tekmar has a t-stat that calcs it from outdoor temp.

    Tekmar has the 553 communicating thermostat that has a built in humidity sensor. It marries well with the new house control, 406 I believe. The water temp is then always kept 2 degrees above dew point. This setup is for a 2 pipe heating/cooling system. If you want to add air conditioning to work in concert with the floor cooling, you need the 557 thermostat to control the fan coil and set the rest of the 553's as part of an air group.
