Wall thermostat problem

[Gardner Yeaw]

Don,
Thanks for the response. I guess I'm getting old and just don't
trust the new fangeled 'digital' things. But really, thanks for the
explanation. My original units do seem to have a mind of their own.
The unique "boyoiyoing" sound when it shuts off is always a
reasurance during the night that it is working, and it wakes you up
just to be sure you are paying attention.

battery powered, so yes, they retain their memory. In the 90 Bird,
the original thermostats are a mixture - mercury for the heat, but
digital for the A/C. Those digitals are A/C powered, and while they
maintain memory, they revert to an off condition when there is
momentary power loss. I intended to replace one of those, but
instead opted for an in-shroud control when replacing an A/C.

differences - the digitals most use don't offer such "features." The
points are: easy precision setting, low precise hysteresis, and no
issues of contact sticking. The mercuries I replaced had high and
variable hysteresis, in one case more than 10 degrees between off
and on.
