Honeywell thermostat CM927 incorrect display. The
Honeywell thermostat CM927 incorrect display. The screen will not display the numbers correctly. There are sections of numbers missing so we are unable to read it. We have tried replacing the batteries which doesn't make any difference. We think the unit is about 4 years old. Any advise?
