Lockout Feature
Your thermostat has the ability to lock out adjustment by other users. This
may be useful in public locations. Only the on/off switch and the GFCI test
button will then operate.
1.
Press the down
and
up button at the same time and hold for 1 second.
LOCK
will show on the display.
2.
To cancel this lockout, the down and up button must be pressed and held
for 1 second. The thermostat will return to the normal operating mode.
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
setpoint temporarily.
2.
Press the GFCI Test button on the side of the thermostat.
GFCI TRIP
should show on the display and a red light will 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 6
“Troubleshooting”
for
help.

6. 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 display.
1. Check wiring connections.
2. Check circuit breaker or other protection “upstream” of
thermostat.
3. Check the 14-pin connection on the back of the Front
Module. Sometimes the pins can become misaligned when
connecting the Front Module to the Power Module.
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.
Er 1 (only at startup)
Floor sensor not correct type or out of range. Check floor
sensor resistance.
Er 2
Floor sensor short-circuited. Replace sensor or Reset
Factory Defaults (section 4).
Er 3
Floor sensor not attached and thermostat in floor sense
mode. Turn off power at circuit breaker and attach sensor.
Or Reset Factory Defaults (section 4).
Er 4 or Er 5
Internal air sensor is faulty. Replace thermostat or
operate in floor sense mode.
Er 6
Internal temperature overlimit. Make sure sunlight is
not directed at the thermostat or other heat source in
proximity. Otherwise, turn off power at breaker and
contact factory.
Er 7
1. Check the 14-pin connection on the back of the Front
Module. Sometimes the pins can become misaligned when
connecting the Front Module to the Power Module.
2. “End-of-life” indication. GFCI will no longer function
correctly or safely. Reset circuit breaker, otherwise replace
thermostat.
