Do you have any specification from the organ maker/installer/tuner on
the differential required
to be maintained? Has the installation been modified -- if so, would
seem it would have been their job to make sure of ambient conditions
(just a question so maybe you can throw the onus onto somebody else
I am the installer/builder/organist. I
have monitored this for the 20 years
since installing
the instrument. It is worse now because
of new setback thermostats in the
church. This was something I have
always wanted to do, but never had the
ambition. Now, it is more important
because of the greater temperature
differences.

I guess the onus _did_ get shifted to the organ contractor...

Don't suppose there's any convenient way to get a side duct run from
off the sanctuary HVAC system?

Still would seem likely that imply an on/off control and a timer for
the routine service schedule would be adequate.

Well, that is another possible idea.
One of the HVAC systems is right next
to the organ chamber. I could put a
return duct in the chamber. This would
tend to suck church air through the open
shutters, thus equalizing temps. I
am currently waiting for the HVAC guy to
come back from vacation, to
discuss this with him.
