non-mercury stats

carol_3 Member Posts: 397
I've been hearing a lot of concern about what happens when there are no more mercury bulb thermostats. Is everyone going to have to change to the (dreaded by some folks)digital thermostats?

The answer is no. And the changeover will be simpler than many feared. Honeywell, at least, is planning to change just the insides of the old standard thermostats such as the T87 round and the T822 heat only rectangular. The thermostats will look and work just like the old ones. The difference is that when you open them up--no mercury bulb.
