Test the GFCI
There is a GFCI (Ground Fault Circuit Interrupter) inside the thermostat. It
is designed to help protect people from possible electrical shock if the floor
warming system has been damaged.
To make sure the GFCI is operating, test it after it is installed and once each
month:
1.
Make sure the thermostat is
HEATING
. You may need to increase the
temperature temporarily.
2.
Press the GFCI Test button on the side of the thermostat. A red light should
show next to the GFCI Test button. You should also hear a click, indicating
power has been removed from the floor warming system. If any of these
indicators fail, turn off the thermostat and replace it. Do not continue to use.
3.
To reset the GFCI, slide the On/Off switch off and back on. If the GFCI does
not reset, turn the thermostat off and go to section 4
“Troubleshooting”
for
help.

4. Troubleshooting
Problem
Solution
Thermostat works
but no heat from the
system.
1. Check wiring connections.
2. If GFCI is tripped, reset thermostat with on/off switch.
3. Check resistances on floor warming system. See
manual for system.
No lights showing.
1. Check wiring connections.
2. Check circuit breaker or other protection “upstream” of
thermostat.
GFCI is tripped.
1. Check wiring connections.
2. Reset thermostat by switching off/on.
3. Check resistances on floor warming system. See
manual for system.
Right light blinking
on front of
thermostat.
Floor sensor or air sensor is faulty:
> 1s on / 1s off : floor sensor fault. Check connections,
replace floor sensor, or disconnect floor sensor and use
air sensing.
> 0.5s on / 0.5s off : air sensor fault. Connect floor
sensor, or replace thermostat.
3. Operation
On/Off Switch
1.
Slide the on/off switch to the upper
position, turning the thermostat on. A green
light will show on the front indicating the
thermostat is turned on. If the light is amber, it
indicates power is applied to the floor warming
system.
2.
To turn the thermostat off anytime, slide the
on/off switch to the lower position. No heating
will occur.
Adjust the Temperature
1.
Turn the dial clockwise to increase the floor temperature. The light on the
front will be amber when power is applied to the floor warming system.
2.
Turn the dial counterclockwise to decrease the floor temperature.
Air or Floor Sensing
During installation, your thermostat should have been connected to a
floor sensor to be embedded with the floor warming system. This is the
recommended method to properly control the system.
However, if the floor sensor was not connected, the thermostat will sense the
air temperature instead, becoming an air thermostat.
