Introduction

The thermostat can switch on your heating system at predetermined times on dierent 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 pre-programmed 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.

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 o and stay o, it was nuisance tripping and the system is operating correctly. If this does not occur, there is a ground fault! Contact your electrical installer.

Active Display

After 1 minute without user activity the display will go into idle mode (the display backlight will turn o). Press any key to activate the display.

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.

Step 2: Choosing the weekly schedule for your program. You have the following options:

5:2 will give you 5 days (Monday to Friday) with the same four events

(Morning, Out, Home, Night) and 2 days (Saturday and Sunday) with the same two events (Morning and Night).

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.

1 With Active Display (backlight on) press OK to activate the menu. 2 Press the Up or Down buttons until the SCHEDULE option ﬂashes. 3 Press the OK button. 4 Press the Up or Down buttons until the required program

(5:2, 6:1 or 7:0) ﬂashes in the lower part of the display.

5 Press the OK button.

SCHEDULE

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.

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 With Active Display (backlight on) press OK 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.

Step 3: Select the time and temperature settings for each event in the program of days selected in the previous step.

1 Press the Up or Down buttons until the PROGRAM option ﬂashes. 2 Press the OK button. 3 Press the Up or Down buttons until the day(s) that you wish to

program ﬂash in the lower part of the display, e.g. MON TUE WED THU FRI.

4 Press the OK button. The symbol for the ﬁrst event (e.g. morning)

will now ﬂash.

5 Press the OK button. The time will ﬂash, allowing you to set the time

at which you want the period to begin. The time can be set in an interval of 15 minuttes.

6 Press the Up or Down buttons until the required time is displayed. 7 Press the OK button. The temperature setting will now ﬂash in the

upper part of the display.

Type UCG/UDG English

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.

6 Press the Up or Down buttons until ON ﬂashes. 7 Press the OK button. 8 Follow the Exit Menu procedure to exit the menu.

Please note: The adaptive 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 function 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 function has been activated, it has learned when the heating must be switched on to attain the required temperature.

6 Press the Up or Down buttons to select one of the four types of

control: ROOM: The built-in room sensor is used. Only room temperature is controlled.

FLOOR: A ﬂoor sensor is used. Only ﬂoor temperature is controlled. 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 o 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).

7 Press the OK button. 8 If FLOOR or ROOM LIMIT is chosen, maximum and minimum ﬂoor

temperatures can now be set. Press the Up or Down buttons to set the High temperature. Press OK and set the Low temperature. Press the OK button.
