INSTALLATION
This thermostat is designed to control electric floor-warming 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.
A certified electrician must install the thermostat.
PARTS INCLUDED
-
One (1) FTGF2P (240 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 OF THE HEATING SYSTEM AT THE MAIN POWER
PANEL TO AVOID ELECTRICAL SHOCK. Keep air vents of the thermostat
clean and free from obstructions.
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 with the thermostat.
Secure the thermostat using two
(2) 6-32 screws. Once the
thermostat is properly installed,
return power to heating system.
240 V Line
240 VAC
Note 1: All cables and connections 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 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 temperature sensor wire cannot cross any
heater wires and the sensing
probe must not be directly ON
or adjacent to a heating wire.
Power-up
240 VAC
To power up thermostat:
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.
L0 will appear if temperature is below 0 °C
(30 °F), temperature probe defective (open) or not
connected. Also, the heating indicator will be
present on display and the relay will be closed
(current going in the load).
HI will appear if temperature higher than 60 °C
(140 °F) or temperature probe shorted.
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.
OPERATING MODES
