What does GFCI mean?

Ground Fault Circuit Interrupter. This safety device terminates the electrical power to the radiant heat system immediately in the event of damage to a wire or another catastrophe. A GFCI is required by electric code for floor heating applications, just like it’s required in most North American bathroom outlets. We always recommend one of our floor heat sensing Thermostats with its built-in GFCI protection.
