We live in a house that's approx. 2000 sq. ft. We have a heat pump
with a zone system. The main thermostat is in the upstairs master
bedroom, there is another thermostat in my son's room upstairs, and
there is 1 thermostat downstairs. Here is my problem: we can't
control the temp. in the house! The main thermostat is set at 74
degrees. We know that we can control the airflow by turning our son's

wasn't big enough for our house. Darned contractor! What a rip off!
