Installation

Wall mount (on wall, 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

Error code	Description
Err.2	Underfloor heating sensor is not installed. Thermostat stops Heating. – Check whether you’ve installed the sensor correctly and the sensor is the correct specifications. Also, check the sensors specifications and your thermostat advanced settings (100K, 10K)
Err.1	Sensor in thermostat is malfunctioning. Thermostat stops Heating. – Turn the device on and off. Try removing the main power supply – this should be done by a professional electrician! If that doesn’t help – turn to your point of sale or our service centres.

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 schedule programs cannot be set. If you want to enable Heating schedule 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 on 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 The thermostat has an option of displaying the current time or currently set temperature of heating. With a short press on the middle menu button (button 3) you change the display from one to another.

Temporary temperature change

• Temporary temperature change means, that if you currently want to change the temperature which 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 temporary 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 temperature set at 22.0°C.
• You can activate the temporary temperature change by pressing 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 schedule program starts.
• If you’ve set everything correctly, the device will show symbols of a clock (using schedule, display description 7) and a hand (manual temperature change, display description 8). You can exit this function anytime by turning the thermostat off and on or by waiting for the next program to start.. The device will then show only a symbol of a clock, as the heating program schedule will be on.

Permanent (constant) temperature change

• 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.
• This function is automaticaly turned on when the heating schedule program is disabled in the advanced settings. When the function is enabled, a hand symbol is shown on the display.  symbol in not visible anymore.
• If you want to change the set temperature, you can do that by pressing buttons.
• This function is usefull if you’re away for holiday or a longer time and want to keep the lowest, ECO room temperature you want.

Setting the day and time

• You can set the time and date when the device is turned off (the screen displays OFF). Now hold the button for 5 seconds. Now, you’re in the date and time setting menu.
• First, you can see that hours are blinking at the top right side of the screen, which means that you’re changing this value.
• You can change the values by pressing  and move to changing the next time, date setting by pressing the button. You can set hours, minutes, day, month and year.
• When you’re done setting the day and time, press the on/off button (button 1).

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 just turn it off. 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 which you’re editing starts to blink. That means that you’re editing for the selected day. You change the values by pressing the buttons and go to the next setting with the middle menu button (button description 3). All the settings will be automaticly saved if you don’t press any button for more than 10 seconds. First you have to select for which day you’ll be setting the schedule. When you select the day, press the menu button and then you’ll proceed to setting the time of 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.
