MODEL TH111GFCI-NP 120 VAC
SUMMARY
OPTIONS SELECTION
At the back of the thermostat, there is one selection switches to set at
your preferences.
Temperature in °C or °F.
TO SET TEMPERATURE
Press on or once to see setpoint temperature appear on display. Every
subsequent press will change the setpoint temperature by one degree.
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 (ECONOMIC) 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 (VACATION) SETPOINT TEMPERATURE
To program the Vacation temperature, select the desired degree using the
buttons and press on the and buttons simultaneously until the
icon is displayed (app. 3 seconds).
CHECKING GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
Adjust the setpoint temperature until heating indicator (flames) appears on
display. Press TEST button. The test is conclusive if the warning light (GFCI) on
thermostat is ON and power to the load is cut-off (flames remain on display
though). If these events do not occur, check the installation. Press on RESET but-
ton to reset the GFCI.
INSTALLATION
Parts included:
One (1)
TH111GFCI-NP (120 VAC) thermostat
Two (2)
6-32 screws
Four (4)
Solderless connectors (for copper wire)
One (1)
Temperature sensor with a 15 foot extension
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER
PANEL TO AVOID ELECTRICAL SHOCK. KEEP AIR VENTS OF THE
THERMOSTAT CLEAN AND OBSTRUCTION FREE.
This thermostat should be installed by an electrician or experienced technician.
The thermostat must be used with a circuit breaker or fuse.
This thermostat was designed to control floor electric heating systems. The
resistive load must not exceed 2000 watts @ 120 VAC (16.7 A). The
thermostat is equipped with a ground fault circuit interrupter (GFCI) and
therefore the isolation of the line and load is required for operation. The
polarity of line connection must be respected. During a ground fault, only the
current in the black wire of the load will be cut-off from the 120 V line.
Connect thermostat as shown on diagram.
1) CONNECTING WIRES AND MOUNTING THERMOSTAT
Connect the rear thermostat wires to the power supply 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
withthe thermostat. Secure the thermostat using two (2) 6-32 screws
1 1/4 inches long. Once the thermostat is properly installed, return power
to heating system.
2) CONNECTING TEMPERATURE SENSOR WIRE
Connect the sensor wire to the two lower screws of the terminal block at the
back of the thermostat (no polarity need 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
perfomance. The sensing probe should be centered between the wires in the
mat. The probe wire cannot cross any heater wires and the temperature sensor
must not be directly or adjacent to a heating wire.
