3. Introduction

Congratulations on the purchase of your new touch

thermostat. We hope that you will enjoy the ease of use

oered 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.

Contents

PAGE 5

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. General Operation

PAGE 6

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 eect 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.

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 o, 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) 1/2

Contents

PAGE 8

The red LED on the right of the thermostat can indicate four dierent GFCI states:

1. LED o – 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 o and then back on again. If the thermostat re-enters ERROR state, ei-

ther 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 o 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.

5. Ground Fault: (GFCI) 2/2
