Customer Question

The batteries went dead iny Honeywell and I changed them but didn't realize it had to be turned off first. New batteries will not bring the temp back up on the screen The thermostat is not giving me temp. So I can change it. Compressor keeps going off and the house is hot. I can get it to come on now and then but with no temp in the screen it just goes back off.
