Turn control to off. Remove the batteries for at least one hour. If the display message still reads "bat lo", leave control off, batteries out, and disconnect the red wire on back and wait another hour. Reconnect red wire, put new batteries in and turn system on. It's like a reboot.

the trouble with rechargable batteries is their voltage is low to start with even when charged. they only give 1.2 volts each instead of 1.5 volts from proper AA bateries. I use Energizer Lithiums in all my camers and they are great and last a long time. You can find cheap suppliers on eBay I use a site called 7dayshop.com in jersey (europe).

The T8132A thermstat requires 2 AA alkaline batteries for operation as the T8131 uses the 24VAC souce transformer with battery back up. If new batteries did not fix the problem follow product user manual to reset and program the thermostat. This should clear any errors or problems. If the problem persists then replace the thermostat. If you do not feel confident you can accomplish the task then you should call a licensed HVAC technician to troubleshoot the issue as the wrong settings could potentially cause permanent damage to your system.
