1. Connecting wires and mounting thermostat
PROGRAMMABLE
FloorStat
Connect the rear thermostat wires to the power supply and to the load using
solderless connectors for copper wires. See schematic diagram.
PART NO. 500600-120
SUMMARY
OPTIONS SELECTION
At the back of the thermostat, there are four selection switches to set
your preferences. The first is not used. The next three set:
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
(ECONOMIC) 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.

or
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 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 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 temperature sensor wire cannot cross any heater wires and
the sensing probe must not be directly or adjacent to a heating wire.

Power-up
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.
The message L0 or HI will appear on the display
if the temperature sensor is defective or the
temperature 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).
INSTALLATION
This thermostat is designed to control floor electric heating systems. The
resistive load must not exceed 2000 watts (NI) @ 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 are required for operation. The polarity of
line connection (line and neutral) must be respected. During a ground fault, only
the current in the black wire (line) of the load will be cut-off. Connect thermostat
as shown on diagram.
Electricians or experienced technicians should install the thermostat.
This thermostat is designed to be used with a self-protected heating system
equipped with thermal cut off and circuit breaker.
PARTS INCLUDED
• One (1) 500600-120 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.

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.

Early start function
The thermostat is providing a built-in function enabling it to calculate the
optimum time to start the heating system to achieve the desired temperature
setting at the programmed time. This function could start the heating system
as early as 6 hours prior to the programmed time. To enable this function,
set the switch E.S. to “ON” at the back of the thermostat.
PROGRAMMING

Bed time
NOTE : For temperature increases (Prog. 1 and 3), allow at least 15 minutes
per °C. If you have lowered the temperature by 3°C during the night and you
wake up at 7 a.m., change the setting at 6:15 a.m.
For savings to be obtained, you must lower the temperature for a period of 2 to
3 times the delay required to bring the temperature back to your comfort level.
Example: If your system takes one hour to go from your saving temperature
level to your comfort temperature Ievel, it is useless to lower the temperature
for a period less than 3 hours.
