power outages cause the thermostat to require configuation...media
type, humidifier type, etc. If this is not done, the hvac does not
come on. It just waits for someone to configure the thermostat. The
tstat does not take a battery. Any ideas?

Sounds like a straight forward job for a HVAC service
company.

Plug the air handler/furnace into an UPS with external batteries, the APC
SUA2200XL would work nicely. When the power fails turn off the system ASAP
to save the battery life then turn it back on afterwards when power is
restored. This means you still have to fiddle with the T-stat but at least
it is just "flipping a switch" instead of reprogramming it.

Some of the serial controlled controls DO NOT have batteries, they have an
E-Prom and memory chips that are supposed to remember what all the settings
are. If it goes to default settings when power is lost, there is an issue
with either the control itself or one of the other mother baords in the
system. There is a reason I don't install new systems using the serial
control wiring.

Most of them are using pin and socket type connector strips between the
wall plate and control head.

They do on the cheap ones folks get from the big box stores, but not on the
Honeywell controls that I use.

I thought she said she could only swallow if it was hard.

*She* told him to spit it out cause it didn't belong to him.

I thought about that but wondered if the control board would go into lockout
mode when nothing responded to its commands, IE the pressure switch on the
draft inducer. If it did it requires a power cycle of the board and then
you are back at square 1.
