I understand the concept of setting the boiler temperature lower in the warmer weather and hotter in the dead of winter. I've seen TACO, B & G, and Honeywell all have zone controllers with the outdoor reset feature. The boiler temperature (low and high limit) are on the aquastat. They are hard wired by way of the adjustment dial, at least on my Honeywell on my oil unit. So how does a zone controller adjust the boiler temp? Do you need to change aquastats so it can communicate with the zone controller or am I just being as dumb as a bag of rocks?
