Installation

Wall mount (dose – socket)
First, remove the back of the thermostat. Do that by using a straight screwdriver and carefully rise the front cover from the bottom up. While doing that you will notice a small flex cable attached to the back and the front of the case. Be careful not tearing it.
You have to remove the cable from the front part of the case. Do it carefully. Now, the thermostat should be separated on two parts – front (screen) and back (electrical connection…).

When the parts are separated, take the back part and make the electrical wiring.
Once again, the assembly should be carried out by a qualified person and read all safety instructions and warnings before assembly. Keep main power off all the time!
Use the electrical wiring scheme on the right side for help.

Now follows the installation of the back part into the wall socket. For help use the picture below. Two screws are attached for easier installation. Be careful to install the back part the right orientation as the small “tongue” part on the bottom should be looking towards the floor.

When you’ve attached the back part on the wall socket, you can connect the back part with the front one. You can do that by carefully attaching the cable to the front part and then pushing the front part of the case on the already installed one. The thermostat should now be installed and ready for use

Possible error codes
Below is a description of possible error codes, which might show during thermostat use.

Error code	Description
Err.3	The sensor in the thermostat is in a short circuit. The thermostat stops Heating.
Err.4	The sensor in the thermostat is malfunctioning. The thermostat stops Heating.

Using the thermostat – First steps, basics and description of functions, settings
The thermostat is very easy to use but it offers many advanced functions. For a quick and easy start, the instructions will be explained in the next pages and we advise that you go through them for even easier use.
By default, the thermostat has Heating schedule programs DISABLED. This means, that out of the box, you can only set the permanent, constant temperature, and Heating scheduled programs cannot be set.
If you want to enable Heating scheduled programming, you’ll have to follow the part of advanced settings for setting the heating programs of the thermostat.

Turning ON / OFF
The thermostat can be turned ON or OFF by a short press of a button for turning on/off (see button description 1)

Changing the values
The values are always changed by short pressing the (changing value, button description 4) and ( changing value, button description 5) buttons.

Displaying time and day
You can check the current time and day by simply short-pressing button (button description 2). The device has to be turned on to use this function.

Temporary temperature change
Temporary temperature change means, that if you currently want to change the temperature it will stay changed until the next Heating program change (if you’re using Heating schedule programs – otherwise, a permanent, constant temperature change is made).
For example – Currently, the time is 13:00 and the Heating temperature is set to 20.0°C. You temporarily change the temperature to 24.0°C and the thermostat will keep this set value until the next Heating schedule change, which you’ve set at 14:30 with the temperature set at 22.0°C.
You can activate the temporary temperature change by pressing or buttons, when you’re not in any menu and the device is turned on. When you press one of those two buttons, the currently set temperature starts to blink. Now, set it to your desired value and when you’re satisfied with the temperature, stop pressing the buttons and the device will save the settings itself and start to use the new set temperature until the next Heating scheduled program starts.
If you’ve set everything correctly, the device will show symbols of a clock (using a schedule, display description 14) and a hand (manual temperature change, display description 13). You can exit this function anytime by simply pressing the middle menu button (button description 3) and the thermostat will go back to using the currently set Heating scheduled program. The device will show only a symbol of a clock.

Permanent (constant) temperature change
The function of permanent temperature change means, that when the function is enabled, the thermostat ignores all of the currently set schedules of Heating programs until manually canceled and uses your manually set temperature.
You can turn on the function when the device is turned on and is not in any of the menus then you shortly press the middle menu button (button description 3). Only a symbol for hand is displayed below (display description 13) and the Heating schedule programs are turned off. Set the temperature by pressing or buttons. When you’re satisfied with your set temperature, stop pressing the buttons and the device will save the settings by itself. Your new currently set temperature will be kept until you cancel it by shortly pressing the middle button (button description 3).
This function is also usefull if you’re away for a holiday or a long time and want to keep the lowest room temperature you want.

Setting the day and time
With a short press on the button, the thermostat will show you the current set time and day. If you press the button again (or just double press it at the start), you will enter the day and time edit mode. First, the minute’s position is blinking. Change the value to the current minutes by using buttons or . After you’re done with setting the minutes, short press the button to enter editing current hour. Now the hour position should blink. Again, change the hour value. When you’ve set the hour, short pres the button again and now you’re editing the current day. Again, change the value and after you’re done setting the current time and day. You can exit editing by pressing the button or just wait for the device to save the values itself after a few seconds.

Setting the Heating Schedule Programs
The condition for setting the Heating schedule is that the Heating programs are turned on (it is turned off by default) in the advanced settings.
Before proceeding, check the advanced thermostat settings. Depending on the set advanced thermostat settings, you can set on how the schedule program works. In advanced settings, you can set your schedule for 7 days (each day) or 5 + 2 days or 5 + 1 + 1 days or just turn it off. Also, you can set the number of daily switches to 4 or 6.
The Heating schedule can be easily edited via the main editing menu – the thermostat must be turned on, then hold (5 seconds) the middle menu button (button description 3). Now you’re in the program editing menu.
When you’re in the Heating schedule programs editing menu, you’ll see on the right side of the screen a blinking icon (sun, moon, house…) which shows for which program switch you’re currently editing the program. Also at the top of the screen, the day or days start to blink. That means that you’re editing for the selected day or days.
You change the values by pressing the or buttons and go to the next set with the middle menu button (button description 3). All the settings will be automatically saved if you don’t press any button for more than 10 seconds.
Firstly you have to select for which day you’ll be setting the schedule. When you select the day or days, press the menu button and then you’ll proceed to set the time when this schedule will start. When you’re done setting the time, press the middle menu button and you’ll be setting the temperature for that schedule. Set the desired temperature and again press the menu button. Now you’re done setting the settings for the first Heating schedule switch of the program. Now a different icon on the right (sun, moon, house) should blink, which indicates that you’re editing for the next Heating program switch. You can take a look at examples of predefined Heating scheduled programs on the next pages.
