Our maple chase,9600 thermostat is showing lo battery. I have changed the batteries and checked charge. The fuse is good,(I think) It is still showing low battery. Thanks.

Is there any evidence of corrosion due to battery leakage? If so, cleaning the battery contacts may correct the problem.

Or you may look at buying a good honeywell themostat. Just a thought. If you do decide to replace thermostat, make sure you get one that is compatible with your system. Wiring should be pretty straight forward. Let us know what you decide, and how things work out.

Thanks to all that responded. I installed a new Honeywell, the batteries still showed low. I changed the batteries again and the new thermostat worked. I am going to reinstall the old one when I warm up to see if it was just the batteries.

Glad you got it working. If old thermostat works with the new batteries, hopefully you can return the honeywell. Although, I think you may have better luck with the honeywell for a longer period. Overall, just glad your problem is solved. Take care,
