My house has two zoned heat. The upstairs is warm and the thermastat seems to be regulating when the heat upstairs goes on and off. But the downstairs is freezing. The heat won't go on and everytime I try to change the setting on the thermastat is won't take the changes and the heat won't go on. Before I call in a service person would it be best if I just go to Home Depot and buy a new thermastat?
