No batteries in this one it uses a cap. to maintain the program. Did you remove the stat to chech for batteries? If so check the alignment of the six tiny pins on the sub base as they are very easy to bend when re installing the stat. If you did'nt.
Check for power at the furnace. If neither one is the case, I have replaced many of this stat with a Honeywell Focus Pro 6000 stat

Is there a battery in the t8000c thermostat the screen is blank


There should be a couple of AAA batts in it. Grab all 4 corners and pull straight out & off the mounting plate. If no batteries are installed it is hard wired & the problem is at the air handler(blown blade fuse or open transformer winding). When you reinstall batteries make sure there is no corrosion. And careful when you put the tstat back onto the base. There are some small pins that need to align with its holes/terminals. Honeywell has a great 1-800 support #. Should be on the tstat.

The remote batteries could be defective or installed incorrectly. Try removing the batteries, pressing all buttons to eliminate the possibility of a stuck one, reinstalling batteries and testing operation. If no operation, the remote may have failed or there could be failure at the wall unit.

LG Model: LWHD1500ER - I would like the unit's compressor to remain on constantly. The temp guage seems to be off and shuts down the compressor. Can I bypass the temp guage to leave th ecompressor...


You can but the unit will have not control over temperature, and you can cause the unit to freeze up or slug the compressor w/ liquid refrigerant causing premature compressor failure. I would recommend replacing the thermostat if it is not holding proper temperature, but if dead set on bypassing it use a volt/ohm meter after unplugging it to find the normally open contacts and wire those wires together taking into consideration that the fan must run constantly with the compressor.

When we have a power bump the unit reverts back to factory settings, Can a ups be added to the control board to eliminate this problem?


Not sure why your unit would reset to factory settings, it's usually the thermostat settings that control the unit and resets when you have a power failure. Most thermostats have a battery in then to power the thermostat during a power failure. They usually only maintain the power from 15 to 30 minutes to maintain your settings, before defaulting back to factory settings. After every power failure you usually have to replace the batteries.

T8000c honeywell thermostat is blank


This unit doesn't require a battery. It runs off the 24v from the unit. Check that your transformer is still working. Check the control board for 24v pwr. and main pwr. Check your breaker to the unit. It could be as simple as a bad stat too. You can check by using a jumper wire and jumping across from r term. to y term.
