Mechanical Stats With "Dirty" Power
The other scenario where they may be a good choice is when dealing with generator or solar power or in places that are prone to power surges.
We've traditionally dealt with folks who use our products with utility power, which in general is very reliable and consistent. Because electronic thermostats have electronic components, power surges or "noise" on a power line could potentially fry them. That isn't an issue with mechanical thermostats because there are no electronic components. That isn't to say that electronic stats aren't designed to withstand a certain amount of power inconsistency, but that will never be an issue for bi-metals, Craig said.
