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, then LOCK should disappear from the display. 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 and the floor should gradually cool off. If any
of these indicators fail, turn off power to the thermostat at the beaker panel.
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

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.
4. Measure voltage between the line side wires, is it the
proper voltage for this specific floor warming system?
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.
Heating occurs at
wrong times.
1. Check that the current time and schedule times are
properly set to AM or PM.
2. On uninsulated concrete SmartStart may start heating
very early. You may turn this feature off if not desired.
Er 1 (only at startup)
Floor sensor not correct type or out of range. Check floor
sensor resistance.
Er 2
Floor sensor short-circuited. Turn off power at breaker and
inspect sensor connections making sure very little copper
is exposed out of terminal connections.
2. Reset Factory Defaults (section 4).
3. Replace floor sensor.
Er 3
Floor sensor not attached and thermostat in floor sense
mode. Turn off power at 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.
Usage
Your thermostat stores in memory the number of hours it is heating. This
information may be useful in calculating the energy used by your floor warming
system.
1.
Press the OPTIONS button and hold for 1 second.
2.
Press the OPTIONS button again until
USAGE
and
1 d
shows
on the display.
3.
The time shown on the display is the number of hours it was
heating today.
4.
Press the down or up button to toggle between the previous
1-day, 7-day, and 30-day usages.
5.
Press the HOLD/RETURN button or wait 15 seconds and the
thermostat will return to the normal operating mode.

Regulator Mode
If you set your thermostat to operate in the regulator mode, it will operate like
a timer. You may adjust the amount of time the floor warming system heats
during a 15-minute repeating cycle as follows:
1.
With the thermostat in the regulator mode, it will show the
heating time and the current cycle time.
2.
Press the down or up button to adjust the heating time from 0
through 15.
• Example: A value of 6 will cause it to heat for 6 minutes of
the 15 minute cycle, and then not heat for 9 minutes of the 15
minute cycle.
• Zero will cause it to never heat.
• 15 will cause it to heat continuously.
3.
The cycle time shown at the bottom of the display is the current time in the
15-minute cycle. It repeats from 0:00 through 14:59 (min:sec).
