    Update: they added an aquastat to each hot water coil return and wired it to the fan board, so the air handler continues to blow during the purge. I did some testing today, and with the aquastat at 120F, we are getting 7-10 minutes of extra heat blowing into the last purging zone after the thermostat is satisfied!

    I have left the purge times at 20 min rather than 5 since we seem to get some value past 5 minutes of purging.

    I also turned on Multipurge for our two zones.

    Fantastic to hear that you’re now taking advantage of thermal purge to recover the heat left in the boiler, @ctboiler28! Aquastats at the air handler are a good solution when the air handlers are in a location that is a challenge to wire back to the end switch at the boiler.
