3. Introduction
Congratulations on the purchase of your new touch thermostat. We hope that you will enjoy the ease of use offered by the touchscreen and the intuitively designed user interface. You can program the thermostat in any way you would like with the options provided under Heating Schedule and User Settings.
The thermostat will switch your underfloor heating system on at predetermined times each day of the week. You can set individual temperatures for up to six separate events for each day of the week. Lowering the temperature when your home is unoccupied will reduce your energy costs without reducing comfort.
The thermostat comes with a preset heating schedule that is suitable for most homes. Unless you change the settings, the thermostat will operate according to this preset heating schedule.
The thermostat features an adaptive function that automatically changes the heating start times to ensure that the required temperature has been reached at the beginning of any specific event. After a few days, the adaptive function will have learned how much earlier the heating must be switched on.
The resistive touchscreen only requires a soft tap with your fingertip to register the touch.
In this manual, the touch areas on the screen will be referred to as buttons.

4. General Operation
The thermostat has two physical buttons. A ground fault (GFCI) test button is located on top of the thermostat, and a power/reset button is located on the right side of the thermostat.
The GFCI should be tested monthly (all settings, including time and date, will be remembered).
The thermostat is an intuitively operated touch thermostat in which the touchscreen is used to navigate through the menus and to change the settings.
The function of the buttons and icons on the home screen can be seen below.

4.1.Navigation Buttons
|
Accept/Back/Cancel/Arrow Up/Arrow Down/Arrow Left/Arrow Right |
|
Whenever you change a parameter setting, you must tap the “Accept” button for the |
|
thermostat to acknowledge the change. |
|
“Accept” is shown on the screen as “√”. |
|
“Back” is shown on the screen as a button marked with a hollow arrow pointing to |
|
the left. |
|
In the various menus and submenus, you will find the “Back” button in the upper |
|
left corner of the touchscreen. |
|
Tap the “Back” button to return to the previous menu. |
|
“Cancel” is shown on the screen as a button marked “X”. |
|
Although “Cancel” has the same effect as “Back”, it also results in all the unsaved |
|
settings being discarded. |
|
As soon as you leave a home screen and enter one of the menus, either a “Back” |
|
button or a “Cancel” button will be shown. |
|
To return to the home screen, tap Back/Cancel once or multiple times depending |
|
on where you are in the menu structure. |
|
“Arrow Up”, “Arrow Down”, “Arrow Left”, and “Arrow Right” are used to toggle |
|
settings and values and to navigate through the menus. The “Arrow Up” and “Arrow |
|
Down” buttons are accelerated buttons. Holding either of them will make the value |
|
change continuously. |

5. Ground Fault: (GFCI) 1/2
|
The GFCI thermostat has a built-in GFCI that ensures personal safety in case of |
|
ground faults. |
|
It is important that the GFCI is tested monthly. Installation and use must be |
|
according to the national and local regulations. |
|
Testing the GFCI: |
|
Press the “TEST” button. |
|
The test is successful if the red LED on the right of the thermostat flashes once |
|
every two seconds and “GROUND FAULT” appears on the display. If this does not |
|
occur, check the installation. |
|
Press the “Standby/Reset” button to reset the GFCI. |
|
The red LED will stop flashing and the display returns to normal appearance. |
|
If the test fails, repeat the test. If it continues to fail, ask an electrician to check the |
|
installation. |
|
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 LED to stop flashing and |
|
stay off, it was nuisance tripping and the system is operating correctly. If this does |
|
not occur, there is a ground fault! In case of a ground fault, it is important to have |
|
the installation checked by a qualified electrician according to local and national |
|
regulations. |
|

5. Ground Fault: (GFCI) 2/2
The red LED on the right of the thermostat can indicate four different GFCI states:
1.LED off – NORMAL state.
2.LED flashing slowly (once every two seconds) – TRIGGERED state. Try pressing the “Standby/Reset” button to reset the GFCI.
3.LED flashing quickly (five flashes per second) – ERROR state. Try switching the power off and then back on again. If the thermostat re-enters ERROR state, either the wiring is wrong (a ground-neutral short exists) or the unit is defective and must be replaced.
4.LED lit constantly – Internal microprocessor malfunction or abnormal hardware fault! Try switching the thermostat off and then back on again. If the LED still lights constantly, the GFCI is defective and the thermostat must be replaced.
Note: The LED lights up briefly without flashing during every power-up.

7. Startup Wizard
When the system has been installed and turned on for the first time, or after you have performed a factory reset, the system will run a Startup Wizard.
The Wizard will take you through tests, which ensure that the thermostat is fully functional. After the tests, the Wizard leads you through a basic setup routine to ensure that you have the right settings.
