can be saved by pressing the “

of the programming steps can be found in Section 3.3.

• If there are days, for which the same program is needed, than it is sufficient

to create that program only once, since it can be easily copied to another

day using the “

COPY

” button as described in Section 3.4. If the same

program is needed for every day, then there is also a possibility to create

the program of all the days together (by selecting 

MON TUE WED THU

FRI SAT SUN

 together during the selection of days). But be aware: if the

program of all the days are created together, than their program can only

be modified together. Therefore, if a different program is needed for at

least one day, then the program of the days should be created separately,

and the repeated programs should be copied using the “

COPY

” button.

• A separate program can be created for the heating and cooling mode,

and these programs are preserved when switching between the modes.

Therefore, if the thermostat is used for both heating and cooling, then

there is no need to modify the program of the thermostat every time a

switch between these modes is performed.

3.2 Recommendations for creating a heating program

The  average  comfort  needs  of  a  person  can  usually  be  satisfied  by  a 

temperature of 19-21°C during the night, and a temperature of 22-23°C during 

the day. During that time of the day, when the family is at work or school, only 

a lower temperature is needed. As heating up and cooling down usually takes 

a long time, it is reasonable to set the start time of the switches 0.5-1 hour 

before the desired time of the modified temperature. The programmability of 

the thermostat provides a perfect solution for this.
For an average working family, a program similar to the one below is 

recommended:
