• SETTING THE ROOM TEMPERATURE 

The stove is capable of sustaining the desired room temperature. It has a room temperature sensor for that purpose. The sensor must 

be placed as far from the stove as its cord allows. The stove reacts to indications of the sensor and increases the heating power after 
the air in the room has cooled down. When the temperature in the room rises, the stove decreases the heating power or even stops. 
There are two ways to set the desired room temperature:
•  use weekly timer programs;
•  set the room temperature manually.

When using weekly timer, you describe time intervals for each day of a week and assign the desired temperatures to them. For more 

information about time programing see the previous chapter Setting the Weekly Timer Programs.

It is also possible to set the desired room temperature manually. If a weekly timer program is active at the same time, the manually 

set room temperature temporary gains priority. This priority disappears, when the current weekly timer program ends. When the next 
time program starts, the room temperature again is controlled by the weekly timer.

To view a current room temperature, press 

 button to enter the Temperature menu section. The actual measured room 

temperature value is indicated on the screen.

Actual measured room temperature.

 To set the desired room temperature, press  . button. The screen indicates the target temperature in the blinking mode. Increase 

or decrease this value with 

 buttons. 

Target temperature value blinks.

When finished, press   button for confirmation. The actual measured room temperature is indicated on the screen again.

 

The room temperature can be set and changed with remote control as well. It is treated by the controller the 

same as a manual setting.

• OUTPUT POWER REGULATION 

The output power defines the maximum burning power level which will be used by the stove to heat the ambient air. There are six 

power levels: 

 

 

 

 

 

. The stove increases burning power by raising 

a rotations quantity of pellet transporting auger per time period and the quantity of supplied air for combustion simultaneously. 
Thus, more pellets and more air are supplied to the burning pot. If the target room temperature is set, the stove chooses the optimal 
burning power level itself. You can interfere with this process and set, for example, a higher power level if you want the stove to 
achieve the target room temperature faster. When your goal is to decrease the consumption of pellets, you can diminish the burning 
power level. In either case, the stove lowers the burning power level itself for better economy, after the target room temperature has
