The GFCI thermostat has a built-in GFCI that ensures personal safety in case of
ground faults. The EGFPD thermostat has a built-in EGFPD that ensures equipment
protection in case of ground faults.
It is important that the GFCI/EGFPD is tested monthly. Installation and use must be
according to the national and local regulations.
Testing 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 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
being 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 o, 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.
