hello I got 1F80 emerson thermostat. my temp is set at 70f. when I came home it was running upto 94F. I couldn't even do anything because batteries seems low, so I changed batteries and bringing the temp down. plz let me know why this happens.. ISN'T IT WHEN THE BATTERIES ARE LOW ON THERMOSTAT IT SHOULD SHUT OFF BY ITSELF RATHER THAN GIVING TOO MUCH HEAT AND RUNNING TEMP HIGH. PLZ LET ME KNOW AT garykalsi@hotmail.com thanks
