I had a "low battery" message flashing on my Maple/Chase 0960T-1 programmable thermostat. When I replaced the batteries the low battery message remained on the display but this time, it was not flashing back and forth and none of the previous settings appeared on the display. None of the switches worked except the fan "on" and "off" switch.

Are you sure the batteries you installed are good? If so I would try turning off the power to the air handler/furnace, remove the batteries, then reinstall the batteries and turn it back on. This may reset the thermostat.

kbhowell, same problem, as is the same problem in the other thread. Read JackT reply, and started looking carefully at the controller, The reset button is directly left of the leftmost button (the change down button). I had done the same as others, replacing batteries over and over again, with no change (batteries were good, V.O.M. tested!)
It now works, and I have some heat (good, it is very cold here).

I always thought of Maple Chase thermostats as disposable. The batteries usually last longer than the thermostat itself.

Just the info I needed! Thanks

Was having the same problem with low bat. Tried same solutions, New batteries & fuses, Nothing worked. Thanks to YopoM, hitting the reset button worked like magic. Thank you!!

I had the same problem! Hit the reset and everything back working again. I love the internet thanks!

YopoM. Your answer in post 3 got me to reset the system.

Thank you

Thank you thank you. Amazing that the instructions in the lid don't let you know about the reset button. When it finally got really cold - reached for the trusty internet - and voilà - the reset button works
