atanytimebypressingtheNext/Savebuttonfor
two seconds. If no key input is received for 90

J. Ground Fault Interrupter (GFCI)
The thermostat has an integral Ground Fault
CircuitInterrupter(GFCI)withEndofLife(EOL)
feature to isolate the heating cable load and to
detect improper operation of the GFCI circuitry.
Test the GFCI circuitry monthly using the following
procedure:
PresstheGFCITESTbuttononcetosimulateafault:
1. If red GFCI light illuminates on the GFCI TEST
button and the “GFI” symbol flashes on the
display (see Figure 18), the circuitry is working as
expectedandhasactivatedtheGFCIprotection
anddisabledthethermostat.PresstheGFCI
RESET button to restore the thermostat to normal
operation.
2. If red GFCI light illuminates and flashes on the
GFCITESTButtonandtheLCDdisplayisblank,the
GFCI circuitry is not functioning properly. If pressing
the GFCI RESET button does not reset the fault,
thenthermostathasreachedEOLandmustbe
replaced with a new thermostat.
IftheGFCItripsandcan’tbereset,turntheOn/
Off button to Off position; there is a possible fault in
theheatingcable.UnderNOcircumstancesshould
the thermostat be bypassed when a fault condition
exists.
K. Power Outage Recovery
Powerinterruptionstothethermostatwillnotaffect
the program settings. However, a power interruption
ofgreaterthanapproximately10minuteswill
require that the clock be reset (see “Setting the
TimeandDay”above).Ofcourse,forextended
power interruptions, the display will remain blank.
L. Sensor Icon
If the thermostat detects a fault with the Floor
Sensor,theSensoriconwillflashontheLCD.
M. Re-set to factory default values for 5/2 Day & 7
Day programs
PressOn/OffbuttontoOffmode,pressandhold
Back/CancelandNext/SaveandDownbuttonsfor
3 seconds. The time schedules will be set to default
values.
