thermostat settings for radiant slab and hydronic fin basebaords

I was looking for input on thermostat settings between basement slab and the main floor zones heated by hydronic baseboard. What's the most efficient setting balancing the multiple thermostats. Should they be the same or basement slab be a few degrees warmer?

    Does the radiant zone have a slab sensor.
    The question is really one of comfort. Put them where you are comfortable, right?
    I have radiant heat. I haven't changed the temperature on the thermostats in years, except I turn the slab sensor off when the AC is on.

    Agree with Steve.

    The most efficient setting, fuel cost wise, would be off:)

    The t-stats are adjustable so you have infinite control. Put it, and leave it at the setting that keeps you comfortable.
