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.

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 pre-

programmed 4-event schedule (see Factory Settings for Automatic 5:2 Program).

Ground Fault Circuit Interrupter (GFCI)

The thermostat is GFCI protected which 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.

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 a day:

•when I wake up in the morning,

•when I am away at work,

•when I come home,

•and at night.

To do so, you must perform the following 3 steps:

Step 1: Select automatic temperature control.

1 Press the OK button to activate the menu.

2 Press the Up or Down buttons until the Mode option ﬂashes. 3 Press the OK button.

4 Press the Up or Down buttons until the Auto options ﬂashes in the upper part of the display.

5 Press the OK button.

Quick Set Temperature

I want to permanently change the temperature for the event currently active in the automatic program.

To do so, you must:

1 Press the Up or Down buttons to set the required temperature for the event currently active.

2 Press the OK button.

The new temperature setting will then be saved and used for this event in the future.

Example: If you change the temperature on a Tuesday morning while the thermostat is running a 5:2 program, the new temperature will apply to all mornings from Monday to Friday.

Adaptive Preheat Feature

I want to ensure that the required temperature has already been reached when I get up in the morning or come home from work.

To do so, you must activate the adaptive function:

1 Press the OK button to activate the menu.

2 Press the Up or Down buttons until the Settings option ﬂashes. 3 Press the OK button.

4 Press the Up or Down buttons until the Adaptive option ﬂashes.

5 Press the OK button. On or Off will now ﬂash in the upper part of the display.

6 Press the Up or Down buttons until On ﬂashes. 7 Press the OK button.

8 Select Exit to exit the option.

Please note: The adaptive preheat function is only related to the 4-event program and only works in connection with going from one event to another where the temperature is going to be raised.

The adaptive preheat feature calculates when the thermostat must start the heating system to ensure that the required temperature is reached at the set time. Three days after the adaptive preheat feature has been activated, it has learned when the heating must be switched on to attain the required temperature.

Offset Temperature

I want to adjust the difference in temperature between the thermostat and my room thermometer.

To do so, you must:

1 Press the OK button twice to activate the menu.

2 Press the Up or Down buttons until the Settings option ﬂashes. 3 Press the OK button.

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.

Application

I want to select the type of temperature control.

2 Press the Up or Down buttons until the Settings option ﬂashes. 3 Press the OK button.

4 Press the Up or Down buttons until the Application option ﬂashes.

5 Press the Up or Down buttons to select one of the four types of control:

Room: The air sensor is used. Only room temperature is controlled.

Floor: A ﬂoor sensor is used. Only ﬂoor 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 ﬂoor 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). (Factory default for 088L5132)

6 Press the OK button.

7 Select Exit to exit the option.

Please note: Usually, the electrician who installed the thermostat will have selected the correct type of temperature control for your application.

Exit Menu

I want to exit a menu.

To do so, you must use the Exit option:

The various menus and submenus contain an Exit option. 1 Press the Up or Down buttons until Exit ﬂashes.

2 Press the OK button. You may have to repeat steps 1 and 2 to return to the ﬁnal Exit option.

Please note: When you activate a menu, the menu item last selected will begin ﬂashing. This allows you to view the latest setting. If, for example, you activate the Mode menu, Man. mode will ﬂash 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 conﬁrming the current setting, i.e. by clicking the OK button.
