Q: Will this work with fan-forced heaters?

I'm very satisfied with this product. It was exactly what I wanted in my travel trailer, for a lot more accurate heating. Now I can pinpoint it to exactly the temperature I want, instead of guessing, sliding the conventional thermostat back and forth. Will for sure save on propane too! Nice back light when adjusting the temperature, making it easy to see even at night.
