Hi, I have a couple of questions
I have a 3-zone hydronic heating system. Only one of the zones uses a
blower. The other 2 use baseboard registers. What are the determining
factors for the temp setting on a L6006A aquastat that is mounted
inline with the zone for the blower?

Why symptoms would I expect to see if the setting is too low AND too
high?

The determining factors are the temperatures required for the type of
heating devices you have.
Cast iron requires one temperature
Copper fin baseboard requires another
Fan coils require another
Radiant floor type heating is another
The limit setting is the highest temperature you want the boiler to be
protected at.
Too low..........you will be cold and the boiler may condense when it
shouldnt.
Too high and the boiler may suffer premature failure and the space
will be uncomfortable.

Ok. I have Copper fan coils. That said, would you be able to suggest a
setpoint? If not, what other info would be needed? Thanks in advance.

Id probably put it at 180 but then Id be using a Tekmar 256 if I were
using a boiler or Id put in at 90%+ Weil-McLain condensing boiler and
not worry about the Tekmar.

Well, you want it hot enough to keep down any condensation on the boiler.
Cool enough that the boiler can absorb heat, so less heat goes up the flue.
If it's both too hot and too cold, you have a schizophrenic aquastat.
