GFCI test button
The thermostat can switch on your heating system at predetermined times on different days of the week. For each day of the
week, you can set individual temperatures for 4 periods, called
events. The thermostat comes with a default schedule suitable for
most installations. Unless you change the settings, the thermostat
will operate in compliance with the default schedule. Lowering the
temperature when the home is unoccupied will reduce your energy
costs without reducing comfort.
Furthermore, the thermostat features an adaptive function that
automatically changes heating period start times so as to ensure
that the required temperature is reached at the required time. After
three days the adaptive function has learned when the heating
must be switched on.

First Time Settings
The first time you turn on the thermostat, time and day must be
set. The time flashes. Set the current time using the Up or Down
buttons. Then press the OK button to confirm the time. The day
of the week will then flash. Select the current day using the Up
and Down buttons. Press the OK button. The thermostat is now
ready for use and will control your heating according to the preprogrammed 4-event schedule (see Factory Settings for Automatic
5:2 Program).
Ground Fault Circuit Interrupter (GFCI)
The thermostat has a built-in GFCI that ensures personal safety in
case of ground faults.
It is important that the GFCI is checked monthly.

Checking the GFCI
Testing can only be performed while the thermostat is calling for
heat.
Adjust the setpoint until the heating symbol (
) appears. Use the
Up button to increase the heating demand and then press the OK
button Wait 10 seconds to allow the thermostat to adjust to the
new setpoint.
Then press the TEST button on the top of the thermostat.
The test is successful if the red light in the TEST button lights up
and GROUND FAULT is shown on the display. If this does not occur, check the installation/contact your electrical installer.
Press the Standby/Reset button to reset the GFCI.
The red light should go out and the display returns to normal appearance.
Press the Down button to return to the original temperature setting.
If the test fails, check the heating cable and thermostat.
6:1 will give you 6 days (Monday to Saturday) with the same
four events (Morning, Out, Home, Night) and 1 day (Sunday)
with the same two events (Day and Night).
7:0 will give you individual settings for each day from Monday
to Sunday.

5 Press the OK button.
SCHEDULE
If during normal operation the GFCI trips without the TEST button
being pressed, there could be a ground fault! To check whether it
is a ground fault or nuisance tripping, press Standby/Reset.
If this causes the red light to go off and stay off, it was nuisance
tripping and the system is operating correctly. If this does not occur, there is a ground fault! Contact your electrical installer.

Regulator: The thermostat functions as a simple regulator and
no sensors are used.
Room limit: The thermostat controls room temperature while
using the external temperature sensor as a limit sensor. If you
choose this option, you must set a maximum and minimum
temperature for the limit sensor, so that the thermostat will
switch the heating off or on if the temperature on the floor
reaches the maximum or minimum temperature respectively.
This can, for instance, be used to avoid excessively high temperatures on wooden flooring (maximum limit) or excessively
cold temperatures on tiled/stone flooring (minimum limit).

Offset is used to compensate for any difference between the
thermostat and a room thermometer. It is possible to adjust the
offset by up to +/- 10°C or +/- 18°F. Once the offset has been set
correctly, the thermostat will display the same temperature as the
thermometer.
If, for example, the thermostat shows 1° too much, the offset
should be set to 1°. The temperature will then be set 1° lower.
