  • Thermostat

    Works very well and is easy to program.

  • Love the heat, hate the failure.

    My SunStat Pro died after almost 4 years. The manual says the error logged is because the GFCI has exceeded its life. Looks like a $40/year service fee to keep my floor running. The warmth is certainly worth the agravation.

  • Does not keep accurate time

    The clock has substantial drift (several minutes each month) Perhaps not so bad as a thermostat, but not great when you depend on the unit to tell you the time in the morning. Was told by a technician that this was because it is driven off the frequency of my electricity which tests normal and no other clocks in my home have this problem....

  • The new one was easy to install and has worked like a charm.

    I bought a new control for my heated floor because the old one failed after only 3 years. But, the new one was easy to install and has worked like a charm.
