SUMMARY
OPTIONS SELECTION
At the back of the thermostat, there are 3 selection switches to set at
your preferences.
Temperature in °C or °F, time in 12 or 24 hours and Early Start function.
TO SET TIME AND DAY
Press on DAY, HOUR and MIN buttons to adjust time and day.
TO RECORD THE (COMFORT) SETPOINT TEMPERATURE
Select chosen setpoint temperature by using or button. Press on
button (2 to 3 seconds) until icon appears on display.
TO RECORD THE (ECONOMY) SETPOINT TEMPERATURE
Select chosen setpoint temperature by using or button.
Press on button (2 to 3 seconds) until icon appears on display .
CHECKING GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
Adjust the setpoint temperature until heating indicator ( ) appears on
display. Press on TEST button. The test is conclusive if the warning light
(GFI) on thermostat is ON and power to the load is cut-off ( remain
on display though). If these events do not occur, check the installation.
Press on RESET button to reset the GFCI.
OPERATING MODES
To select an operating mode, use MODE button.
AUTO: Runs the program. or shows temperature setting
and can override temporarily your programming up to the
next program
MAN: Maintains the selected temperature. or changes
the temperature setting.
Power-up
When power is applied for the first time, the
display must show the time 00:00, the floor
temperature and the Manual mode icon ( ).
Other information might show up on the display if
installation is defective or does not comply with
the instructions. The warning light (GFI) must be
off.
The message L0 or HI will appear on the display
if the temperature sensor is defective or the tem-
perature is below 0 °C (32 °F) or higher than
60 °C (140 °F). Also, the heating indicator will be
present on display and the relay will be closed
(current going in the load).
Checking ground fault circuit interrupter (GFCI)
Adjust the setpoint temperature until
heating indicator ( ) appears on
display. Press on TEST button. The test is
conclusive if the warning light (GFI) on the
thermostat is ON and power to the load is
cut-off. If these events do not occur, check
the installation. Press on RESET button to
reset the GFCI.
If the GFCI test fails:
Check the load wires. The thermostat
must be in heating mode to carry out the
test (heating indicator ON).
The GFCI test should be carried out
monthly
. If the test fails, cut off the electric
power to the heating system and call
customer service or return the thermostat
to your supplier for verification. If the
warning light comes on during normal
operation, cut off power to the heating
system and have an electrician verify the
installation.
MODEL TH111GFCI-P (240 VAC)
INSTALLA
TION
This thermostat is designed to control floor electric heating systems. The
resistive load must not exceed 4000 watts (NI) @ 240 VAC (16.7 A). The
thermostat is equipped with a ground fault circuit interrupter (GFCI) and therefore
the isolation of the line and load are required for operation. During a ground fault,
the two lines of the load will be cut off from the 240 V line. Connect thermostat as
shown on diagram.
Electricians or experienced technicians should install the thermostat.
This thermostat is designed to be used with a circuit breaker.
PARTS INCLUDED
- One (1) TH111 GFCI-P (240 VAC) ther mostat
- Two (2) 6-32 screws
- Four (4) solderless connectors (for copper wire)
- One (1) temperature sensor with a 15 foot extension
TURN OFF POWER OF THE HEATING SYSTEM A
T THE MAIN POWER
PANEL TO AVOID ELECTRICAL SHOCK. Keep air vents of the ther mostat
clean and free from obstructions.
1) Connecting wires and mounting thermostat
Connect the rear thermostat wires
to the 240 V LINE and to the load
using solderless connectors for
copper wires. See schematic
diagram.

Push the excess wire back into
the electrical box to prevent
interference with the thermostat.
Secure the thermostat using two
(2) 6-32 screws. Once the
thermostat is properly installed,
return power to heating system.
NOTE : All cables and connec-
tions must conform to the local
electrical code.
WARNING: Special CO/ALR solderless connectors must be used when
connecting with aluminum conductors.
2) Connecting temperature sensor wire
Connect the temperature sensor
wire to the two lower screws of the
terminal block at the back of the
thermostat (no polarity needs to
be respected). The wire must pass
outside the electrical box and
follow the wall down to the floor.
The sensing probe should be
placed in a representative heat
area for maximum system perfo-
mance. The sensing probe should
be centered between the wires in
the mat. The temperature sensor
wire cannot cross any heater
wires and the sensing probe must
not be directly or adjacent to a
heating wire.

OPERA
TING MODES
The TH111GFCI-P has two (2) operating modes.
M
ANUAL ()
This mode allows you to maintain a constant temperature of the floor.
1- To activate this mode, press on Mode button to display the icon.
2- Set the desired temperature using the buttons or select the
pre-programmed or or settings.
(To select the setting, press on and simultaneously.)
AUTO
MATIC
()
This mode executes your own programming.
To activate this mode, press on Mode button to display the icon.
The or icon indicates which temperature setting is used. Also, the icon
of the program number will be shown.
