I don't have that kind of control over it.  I have one low-voltage
control loop to tell it on/off, and that's it.

It's not, it stays on for a while after that, until the air it's
moving warms up.

I have a thermocouple in the plenum right after the A/C exchanger, the
air in there is nearly freezing.  It reads 41F but I think the
software is bottoming out because it drops fast and just flat-lines at
41F (that thermocouple system is designed for the woodstove - 0C to
1023C).  I'm pretty sure it's OK.  It did have a leak at one point,
and we had an A/C specialist come and redo the joints and recharge it,
it hasn't degraded since then.

Just mine :-)

I have 7200 VAC coming up the driveway (it's 0.3 miles to the road).
