Dual zone conflict
I have dual zone. During winter days (8am to 7pm), the upstairs zone turns down to 5 degrees cooler than the lower level. There's a second stairs that connects to the kitchen. There's constant cold draft coming down from the second level. The lower level thermostat is in the dining room behind the kitchen. With the cold draft, the heat is constantly running in the lower level. Should I increase the heat in the second level as a solution?

Unless you have a hallway door on the upper level you can close. The laws of physics are at play here. Hot air rises because its less dense, and cold air sinks because its heavier. I've found the temprature difference between two floors will be roughly 2-3 degrees F from that alone. Part of the problem if I understand is the lower levels thermostat is in the path of that colder air coming down the stairs. But even if that was moved... if the stairwell between levels is open and has no door, the heat will naturally rush upstairs. |

We have been having problems with our dual zone system, operated by two Simple Comfort 3001 thermostats. When both systems are on, the temperature in one of the zones (typically upstairs when heat is running, downstairs when airconditioning is running) will exceed the limit for that zone, but the...
The question is if this will substantially raise my pg&e bill. The company that came out diagnosed the problem as the damper is not closing properly, nor sending the air to the right vents. The upstair control is sending some of the air downstairs and a couple upstairs do not work at all. So the...
