3. Introduction
Congratulations on the purchase of your new WiFi 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 WiFi-enabled thermostat allows you to both
monitor and control the thermostat remotely from a
web browser, Android or iOS smartphone or tablet –
anytime – anywhere. The thermostat also provides a daily
weather forecast once the WiFi/Weather wizard has been
completed successfully.
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.
The thermostat oers remotely control of your underfloor
heating - through the The OJ Microline® app, which
can be downloaded from both Google Play and App
Store.
With Google Home devices or Amazon Alexa devices
you can integrate with the thermostat. Once connected,
simply ask the Google Assistant or Alexa to turn the
heating up in a given room and let smart technology do
the rest.

The thermostat has two physical buttons. A ground fault (GFCI/EGFPD) test button
is located on top of the thermostat, and a power/reset button is located on the right
side of the thermostat.
Test the GFCI/EGFPD monthly. The test has no influence on the settings; data,
including time and date, will be stored.
The thermostat is an intuitively operated touch thermostat in which the touchscreen
is used to navigate through the menus and to change the settings.

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 repeat 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. The EGFPD thermostat has a built-in EGFPD that ensures equipment
protection in case of ground faults.
It is important that the GFCI/EGFPD is tested monthly. Installation and use must be
according to the national and local regulations.
Testing the GFCI/EGFPD:
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/EGFPD.
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/EGFPD 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.

The red LED on the right of the thermostat can indicate four dierent GFCI/EGFPD
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/EGFPD.
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/EGFPD 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.
