Easy installation and immediate difference

We switched our ceiling cable heat dial thermostats to these and the installation was so easy. We have noticed an almost immediate difference in comfort and control over the ceiling heat. We plan on switching all out and ordering more.

This was the easiest fastest electrical installation I have ever made. It adjusts to changing weather conditions rapidly, displays accurately, will probably save me money.
