Introduction
The Danfoss LX 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 contains an adaptive preheat feature
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 preheat feature learns when the
heating must be switched on.

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 oc-
cur, 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.
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.
4-Event Program
I want the temperature to be controlled automatically in accordance with a program of individual
temperature settings for four separate events during

four events (Morning, Out, Home, Night) and 1 day (Sunday)
with the same two events (Day and Night).

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.

Floor: A fl oor sensor is used. Only fl oor temperature is controlled. (Factory default for 088L5132)
Regulator: The thermostat functions as a simple regulator and
no sensors are used.
Room limit: The thermostat controls room temperature while
using the fl oor 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 fl oor reaches the maximum
or minimum temperature respectively. This can, for instance,
be used to avoid excessively high temperatures on wooden
fl ooring (maximum limit) or excessively cold temperatures
on tiled/stone fl ooring (minimum limit). (Factory default for
088L5132)
6 Press the OK button.
7 Select Exit to exit the option.

The various menus and submenus contain an Exit option.
1 Press the Up or Down buttons until Exit fl ashes.
2 Press the OK button. You may have to repeat steps 1 and 2 to

if you used Man. mode the last time.
This principle also applies to current temperature/time settings.
When you enter the various menus, they always display the value
that was last selected. This allows you to check the current settings.
Should you enter a menu by mistake, you can exit it again without
changing the setting by simply confi rming the current setting, i.e.
by clicking the OK button.
