Hi,

Remove the AC power and the battery for 2-3 minutes, then re-insert the battery and reconnect the AC power and see if the unit is now functioning correctly.

If it is still not working correctly after this then verify that there is 24V AC being supplied to the controller. Use a DMM (Digital Multimeter - Voltmeter function) to check the AC voltage level at the input terminals. (If you do not have a DMM or access to one, suitable DMMs are available from larger hardware stores for about $10 and up).

If there is 24V AC available on the input terminals then you may have to open the unit and do further testing as to what the problem is. It may be a faulty connection on the other side of the AC input terminals for example

The battery is only used to maintain the settings in the event of a power failure, it cannot power the controller.
