suntouch FloorStat 500500-120 User manual

MODEL 500500-120 (120 VAC)
SUMMARY
TO CHANGE THE TEMPERATURE SCALE FROM °C (CELSIUS)
TO °F (FAHRENHEIT) AND BACK
Switch the dip switch on the back of the control to either °C or °F.
Note: The other three dip switches are not used.
TO SET TEMPERATURE
Press on or once to see setpoint temperature appear on
display. Every subsequent press will change the setpoint tempera-
ture 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.
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 button to reset the
GFCI.
INSTALLATION
Parts included:
One (1) 500500-120 (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 FREE OF OBSTRUCTIONS.
This thermostat should be installed by an electrician or experienced
technician. The thermostat must be used with a self-protected
heating system equipped with a thermal cut-off and circuit breaker or
fuse.
This thermostat was designed to control floor electric heating
systems. The resistive load must not exceed 1920 watts at
120 VAC (16.0 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. 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 below.
Push the excess wire back into the electrical box to prevent interfer-
ence 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.

• Recording a setpoint temperature for the (ECONOMIC) setting
Select chosen setpoint temperature by using and buttons.
Keep pressing on the button (2 to 3 seconds) until icon appears
on display.
NOTE: When the temperature setting used is or , you can still
use the or buttons to change the setpoint temperature without
changing the recorded temperature.
• Recalling stored setpoint temperatures
Once stored, both setpoint temperatures can be recalled simply by
selecting the or button.
CHOOSING THE TEMPERATURE SCALE IN °C (CELSIUS)
OR °F (FAHRENHEIT) TO APPEAR ON DISPLAY.
To choose the temperature scale, press the button while pressing
and releasing the RESET button. Then release the button.

POWER UP
To power up thermostat:
When power is applied for the first time, the display must show the
floortemperature. Other information might show up on the display if
installation is defective or does not comply with the instructions. The
warning light (GFCI) must be off.
The message L0 will appear on the display
if the temperature sensor is not hooked up,
is in default or the temperature is below 0°C
(32°F). Also, the heating indicator will be
present on display and the relays will be
close (current going in the load).
The message E1 will appear on the display
if the temperature sensor is short-circuited.
The message HI will appear on the display
if the temperature is higher than (99°F).
If anything else appears on the display,
press the button as you press and
release the RESET button.
CHECKING GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
Adjust the setpoint temperature
until heating indicator ( )
appears on display. Press TEST
button. The test is conclusive if
the warning light (GFCI) 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 ther-
mostat 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 cus-
tomer service or return the
thermostat to your supplier for
verification. If the warning light
comes on during normal opera-
tion, cut off power to the heating
system and have an electrician
verify the installation.
OPERATION
The thermostat has 4 different buttons to control the floor temperature.
The and buttons increase or decrease the setpoint temperature.
The and buttons are used to store and recall two temperature
settings.
• Default values
To erase the recorded setting temperatures ( and ) and replace
their values by the default ones, 30°C (86°F) and 10°C (50°F)
press the button while pressing and releasing the RESET button.
Then release the button.
• Setting a setpoint temperature
Press once the or button to see the setpoint temperature on
display. Every subsequent press will change the setpoint temperature
by one degree.
• Recording setpoint temperature for (COMFORT) and (ECO-
NOMIC) settings
By recording two setpoint temperatures you will be able to go from
the setting to the setting by simply pressing the or button.
• Recording a setpoint temperature for the (COMFORT) setting
Select chosen setpoint temperature by using and buttons.
Keep pressing on the button (2 to 3 seconds) until icon appears
on display.
