robert shaw thermostat says 'lo bat' but battery is fresh

[sofireme]

I tried replacing the batteries twice. The first time the thermostat worked
fine for a couple hours but after that it shuts off and says 'lo bat'. I
referred to the users manual and got nothing.

Thanks, people.

Are you using the right cells (batteries). Rechargeables often develop less
voltage. If so, the thermostat is defective.

Are the contacts clean in the thermostat? Where the batteries go, that is.
Clean them with a pencil eraser. Have you checked the batteries on a meter?

In my furnace, if the safety decides to disconnect it stops juice to the
thermostat which then runs down the back up battery and end up with drained
battery. Usually happens if condensation pump sticks and overflow tells
furnace to turn off. If you have a condensation pump check the sump to see
if it is full. Otherwise you may have a more significant furnace problem.
Condensation pump floats often stick due to algae and sump needs to be
cleaned once in a while.

Hi,
When lo battery is indicated it has few more days juice left to
function. Use good Alkaline ones. If it keeps doing that maybe something
wrong with the 'stat; like cracked solder joint/PCB trace, etc.

Hard to believe that you allow the condensate pump to shut down your
furnace. What's the better option---some water on the floor or frozen
pipes? Do you actually spend time away in the winter unconcerned that a
"sticky" float could trigger frozen pipes?

The issue is condensate backing up into the furnace. I didn't design it....
talk to industry leaders. My house has 3 separate HVAC systems. The only
way my house could freeze is a power failure.

Had same problem with same stat. This worked for me. Pull cover.
heat/off/cool switch to off. Remove batteries. remove red and white wires
(which supply 24 volts to the circuit) hit reset button. Wait 20 minutes.
restore red and white wires, put in batteries. Hit reset again. Wait 2
minutes and it should work.
Basically cut all power for a while and reinstall. Manual apparently
states batteries should be replaced with switch in off position but my
quess is most people don't read the manual. This looks like a basic
software bug. Good luck.

If you want to remove external power from the thermostat, it would seem
it would be a lot easier to just turn off the AC power to the furnace,
instead of removing wires from the thermostat.

I solved the problem by replacing the sole electrolytic capacitor. Works
again. original capacitor was 1000 uf 6 volts. I replaced with 1000 uf at 10
volts which is slightly bigger but the 6 volt one would work. I had the part
and a soldering iron.

You have to replace the electrolytic capacitor. It is the only component that
degrades with time. Mine now works.

Find someone with a soldering iron and replace capacitor. Should cost about 30
cents on line. I spent quitr some time on research and ended up buying a new
thermostat but did repair my RobertShaw in about two minutes.

You do not sound foolish, at all!

I've had similar probs with copper-tops. I bought some brand new
Duracell AA bats and put 'em in my brand new Maglite. Came out to my
van at O dark thirty and turned on my brand new everything flashlight.
It was a dark Wintery morning, jes below freezing. The Duracells
would not light! Not even faintly.

later that day, I bought brand new Energizers and put them in my Maglite.
Very next morning, it was about the same time and temp (dark, jes
below freezing) and the flashlight lit up jes fine. I've never bought
another Duracell, again.

Hey, dip shit, the OP had that problem nearly a decade ago. Pay attention!

The only component that "ages" in this thermostat is the electrolytic

is not an option for most users, but it works.

Not sure if this will help, but I have a TX1500uc / TX1500 Thermostat and the
BATT LOW would not go away after placing fresh new batteries in the device. I
took the batteries out, pressed and held the front buttons, pressed the RESET
button inside the unit, even swapped the Elec/Gas jumper temporarily. Put
everything back the way it was and popped the unit back on the wall and it was
good.

Maybe it is calibrated in degrees Celsius, with manufacturer's
assumption that a reasonable indoor temperature would not be hotter or
colder than that (approx. 44.5 - 88 F).

Bad news. The original thread goes back to 2007. The original poster
never got a good answer so the heat never came on. He was found dead
the following spring when his body thawed and started to smell.

I would have to spend all day clicking on all "full context" hyperlinks
to see if any threads were stale. Is there a USENET reader that
displays some indication that a specific thread is stale? In any case,
thanks for alerting me. Obvious after reading the full original thread
that I was way off base with my comment.

I use Thunderbird portable. It also shows this:

If you follow it back you can see how old the thread is. They often pop
up when someone on HH replies years later.

Even worse was his 218 Gerbils died during the same incident.

And you can probably change it to F in the settings.

Try cleaning the corroded contacts on your thermostat first.

I found a reset button on my 9600. Repat removing the batteries and hold reset button down for approximately 10 sec. Replace batteries and reprogram the thermostat.

[Philcampos]

Omg this worked
