Checking the GFCI/EGFPD
It is important that the GFCI/EGFPD is checked for correct installation and function upon installation and monthly thereafter.
To check the GFCI/EGFPD: Press the “TEST” button.
The test is successful if the red LED on the right of the thermostat flashes once every two seconds and “GROUND FAULT” appears on the display. If this does not occur, check the installation.
Press the “Standby/Reset” button to reset the GFCI/EGFPD.
The red LED will stop flashing and the display returns to its normal appearance.
If the test fails, repeat the test. If it continues to fail, ask an electrician to check the installation.
If, during normal operation, the GFCI/EGFPD trips without the “TEST” button is pressed, there could be a ground fault! To check whether it is a ground fault or nuisance tripping, press “Standby/Reset”. If this causes the red LED to stop flashing and stay off, it was nuisance tripping and the system is operating correctly. If this does not occur, there is a ground fault! In case of a ground fault, it is important to have the installation checked by a qualified electrician according to local and national regulations.
The red LED on the right of the thermostat can indicate four different
