I BOUGHT A OLDER DOUBLE WIDE MANUFACTURE HOME IN LAKELAND…

Customer Question
I BOUGHT A OLDER...

I BOUGHT A OLDER DOUBLE WIDE MANUFACTURE HOME IN LAKELAND FLORIDA THAT HAS A CARRIER AIR CONDITIONER, I AM TRYING TO DETERMINE IF THE T874G155 IS WORKING PROPERLY. HOW CAN I GET THE INSTRUCTIONS

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

THE ONLY WAY WE GET HET IS TO PLACE ALL CONTROL TO MAXIMUM HEAT AND THE SUPPLIMENTAL HEAT (RED LIGHT) ON

Contractor's Assistant: Do you plan on doing the work yourself?

YES SO FR S CHECKING OUT THE THERMOSTAT AT THIS POINT. I HAVENT REPLACED THE FILTER SINCE LAST MATCH

Contractor's Assistant: Anything else we should know to help you best?

A COPY OF HOW THE THERMOSTAT WORKS WOULD BE GREAT FOR STARTERS. THANK YOU
