Thermostat installation

Before thermostat installation, insert two new alkaline AA LR6 1.5V batteries in the battery sockets on the side. For help, see the picture below. After battery installation, the thermostat is ready for use

You can install the thermostat on a wall or on a stand, which came with the package you bought

In any case of the thermostat installation (on wall or portable), be careful not put it near sources of hot or cold air, direct sunlight, draught or other types of temperature influences. Also, make sure that the thermostat is placed at least 30cm away from metal parts and 1 meter from other electrical devices. If you mount the thermostat on a wall, the most optimum height for mounting is 150cm and at least 20cm away from the door, windows, cupboards and similar objects. Also, install the thermostat on the inside wall of the house. If you don’t follow these recommendations, it can happen that the thermostat will not function correctly. Because of signal interference (electrical sources, metal parts, …) or due to incorrect reading of the temperature (drafts, sun, cold or the hot spot,

Getting started

The thermostat is very easy to use. When the thermostat is turned on display should show the current data – current room temperature, set temperature, heating mode, … The thermostat and the receiver are paired by default. If that’s not the case, do the pairing process, described in the instructions. Turning the Thermostat ON and OFF You can turn off the thermostat by holding (3 seconds) the middle menu button . When the thermostat is turned OFF, the screen is turned off also. You can turn ON the thermostat by short pressing the middle menu button . Setting the desired temporary temperature If you don’t want to use the day or night mode temperature, you can easily set your temporary temperature by pressing the + or – buttons. The desired temperature starts to blink on the bottom of the screen and a hand symbol shows on the top right. This mode stays active until you change to a day or night mode. Changing the heating mode – Day or Night With a short press on a middle menu button you can change the heating modes – day comfort mode or night eco mode. If you select the day mode, you’ll be using your higher set temperature and a sun symbol will show on the bottom left of the screen. If you select the night mode, you’ll be using the lower set temperature and a moon symbol will show on the bottom right of the screen. You can set the temperatures for day or night modes in the advanced settings of the thermostat.

Thermostat key lock
For safety reasons you can lock the keypad and by that you disable any future changes on the thermostat. That option can be activated by holding buttons + and – for 3 seconds. On the bottom left of the screen, a lock key will show . You can unlock the thermostat by repeating the process – hold the + and – button for 3 seconds.

Advanced thermostat settings
You can set the temperature limits, heating mode temperatures, hysteresis, etc. Description To access advanced thermostat settings, you have to turn the thermostat off, by holding the middle menu button for 3 seconds. When the thermostat is OFF and the display is not showing anything, you have to hold the middle menu button for 3 seconds. Now, the display should turn on and you should see the first set value and on the bottom of the screen a number “1”, which lets you know, that you’re changing the settings for the first step (check the table below). You change the settings by pressing + or – and move to the next setting by pressing the middle menu button. Any changes made are automatically saved if you don’t press anything for 8 seconds.

Step	Factory default value	Setting options	Description
1	30.0°C	20.0°C – 35.0°C	Here you can set the highest working room temperature for heating.
2	05.0°C	05.0°C – 20.0°C	Here you can set the lowest working room temperature for heating.
3	16.0°C	10.0°C – 20.0°C	Lower, Night mode temperature (ECO)– this temperature is used when you’re using the Night mode, for example, at night or when you’re away.

Step	Factory default value	Setting options	Description
4	21.0°C	20.0°C – 25.0°C	Higher, Day mode temperature         (Comfort) – this temperature is used when you’re using the Day mode, for example, during the day or when you’re at home.
5	On	On / Off	Display backlight – If set to On, the thermostat will use display backlight. If set to Off, the display backlight and the screen will stay dark.
6	00.0°C	-5.0°C – 05.0°C	Temperature display correction – In the event of a deviation of the actual room temperature from the temperature shown to you by the thermostat on the screen, you have the option of adjusting the temperature display. For example. The temperature in the room is 20.0 ° C, the thermostat shows 21.0 ° C. Select a value of -1.
7	Hp	P1/Hp	Heating system control – HP: Constant temperature. The thermostat takes into account the hysteresis – the temperature range, e.g. 0.5°C. For example, you have a heating temperature of 22.0°C and a range of 0.5°C. The heating system starts to operate when the room temperature drops to 21.5 °C and switches off when the temperature reaches 22.5 °C. Pi:  PWM  module  –  thermostat  maintains  temperature  with  minimum temperature ranges. Used in underfloor heating.
8	0.5°C	0.1°C – 05.0°C	Temperature range, hysteresis – This function is active if you have the Hp function enabled under step 7. See description above.
9	On	On / Off	Automatic short-time switching function (circulation pump, valve) – Option of setting the automatic activation function, for example, circulation pumps, valves – this feature allows automatic activation of the circulation pump, or valve for 30 seconds, in the event that there was no power on in the last 24 hours.

Other functions

Connecting the thermostat and the receiver (pairing)
The devices are paired by default. If it occurs that the connection is not active, repeat the pairing procedure. Procedure: Read the instruction for pairing in the receiver user manual. Put the receiver in to pairing mode. Turn off the thermostat until the display is turned off. Now hold the middle menu button AND – button for 3 seconds. The screen should show “-“, which means the thermostat is waiting to be paired. The devices should now automatically pair and the thermostat display should show “1”. Procedure is now finished. Turn both of the devices back on. Perform the communication test by increasing and decreasing the set temperature on the thermostat. The receiver should confirm the communication by blinking LED lights and turning on and off the heating.

Anti-freeze protection
The function makes sure, that when the room temperature falls below 5°C, the thermostat sends an order to the receiver to turn on the heating (turn on the boiler, pump,…) and it stays on until the room temperature reaches 8°C.

Low battery warning
Always insert new alkaline and non-rechargeable batteries when using the thermostat. When the battery replacement symbol appears, the thermostat will only work for an average of 30 days. The battery life itself depends on the use frequency of the thermostat and the quality of the batteries themselves. In case you do not use the thermostat for a long time, we recommend that you remove the batteries from the thermostat. This prevents damage to the device if the battery is leaking or simply extends the life of the batteries.
