[Hai-users] Creeping thermostat calibration?

[Justin Matlock]

Has anyone else noticed the calibration on their RC-122's "creeping"?

I've had about six I've had to adjust the calibration on, a year after
installation. Four of them, I've had to continually adjust -- once a month,
it seems.  On three, I've gone from 30, to 28, to 26, to 23 (same
household).  I've double checked with three digital thermometers, including
a Fluke.. All three thermometers are showing the same temp (to the tenth
degree)... The HAI thermostat is consistently too high (and thus keeping the
A/C on too much).

Weirdest thing.  It's like they're drifting...  I haven't seen this on any
of the RC-112's, which is even stranger, since you'd expect to see the same
behavior since they're basically the same 'stat.
