ENGLISH
This ground fault protection thermostat is different from conventional thermostats. In the event of a ground
fault, the ground fault protection mechanism on the thermostat will trip and quickly stop the flow of
electricity to prevent serious injury.
Definition of a ground fault
Instead of following its normal safe path, electricity passes through a person’s body to reach the ground.
For example, a defective floor heating mat can cause a ground fault.
A ground fault protection thermostat does not protect against circuit overloads, short circuits, or
electrical shocks. For example, you can still receive an electrical shock if you touch bare wires while
standing on a non-conducting surface such as a wood floor.
Ground fault protection reset
When the ground fault protection mechanism trips, the TEST light is On (red). To reset the ground fault
protection, switch the thermostat to Off and back to On. The TEST light will turn off.
End of Life
If the TEST light is flashing permanently the device must be replaced.
