Testing the ground fault protection
To ensure the ground fault protection is always in working order, test it once the thermostat is installed
and on a monthly basis thereafter.
nIncrease the setpoint temperature above the measured temperature in order
to activate the heating system.
oPress the TEST button.
• If the TEST light does NOT turn on, the test has failed. Cut power to the
heating system at the main electrical panel, have an electrician verify the
installation and, if necessary, replace the thermostat.
• If the TEST light turns on, continue the test.
pSwitch the thermostat to Off then back to On.
• If the TEST light turns off, the test has passed. Set the thermostat back to the desired tempera-
ture. The test is now completed.
• If the TEST light remains on, the test has failed. Continue with the rest of the procedure.
qSwitch the circuit breaker (at the service panel) of the heating system to off then back to on.
rRepeat the test. If the test fails again, cut power to the heating system at the main electrical panel,
have an electrician verify the installation and, if necessary, replace the thermostat.
