Proper thermostat location
Please note:
The ideal position to thermostat mounting is about 1,5m under floor level far from heating or cooling sources. Thermostat can be exposed to sunlight or any extreme conditions like for example draft. Because of fire and explosion risk there is not allowed to use thermostat in atmosphere of explosive gases and flammable liquids (eg coal dust). In case if any of listed dangers occur you have to use additional protection measures anti-dust and explosive gases (tight cover) or prevent their formation. Furthermore, thermostat can be used in condensation of water vapor conditions and be exposed to water action.

Time settings
Day/time settings are set using the D, H and M buttons. Please see steps below
how to set time/day:
Operation
Manual mode
There are two temperature setpoint levels at our disposal. In manual mode
chosen setpoint temperature level is maintained permanently until user changes
operation mode or set a different temperature for each level.
- Comfort Mode – in this mode, the thermostat is to maintain a constant day temperature. When the temperature is set manually, e.g. 23°C, the thermostat maintains it until user switches to another operating mode or set a different temperature, e.g. 21°C.
- Economic Mode – in this mode, the thermostat is to maintain the reduced (night) temperature. When the temperature is set manually, e.g. 17°C, the thermostat maintains it until user switches to another mode or set a different temperature, e.g. 19°C.
Comfort mode
In the comfort temperature mode, the thermostat is to maintain a constant day
temperature. The comfort temperature level is indicated by sun icon. To set
the comfort temperature, see the steps below:
Economic mode
In the economic temperature mode, the thermostat is to maintain a reduced
(night) temperature. This is to ensure a more economical operation of the
heating system when, for example, you are away from home. The economic
temperature level is indicated by the moon icon. To set the economic (night)
temperature, see the steps below:
AUTO mode – two schedule types
AUTO Mode – In the automatic mode, the thermostat maintains the set temperature according to the schedule selected by the user. You can choose from 2 types of schedule to manage the temperature during the week.
First type schedule
First type schedule mode is represented by timeline – 24 hours of a day. Empty „boxes” means hours where Economic (Moon) setpoint temperature will be maintained, black „boxes” means hours where Comfort (Sun) setpoint temperature will be maintained.
There are three different configurations in a schedule type 1:
- Two different programs (timelines), separate program for working days (Monday to Friday) and separate program for weekends (Saturday to Sunday)
- Individual programs (timelines) for each day of the week
- Same program (timeline) for the whole week
Second type schedule
Schedule type 2 enables the programming of 6 time intervals per day, with
precision up to 10 minutes. Each of the 6 time intervals allows you to set a
different temperature (schedule type 1 is limited to switching between two
setpoint temperatures (SUN/MOON) at full hours time periods). When creating a
schedule type 2, you must define time and temperature setpoint (thermostat
will start to maintain given setpoint temperature from given time setting).
There are three different schedule configurations:
- Two different programs, separate program for working days (Monday to Friday) and separate program for weekends (Saturday to Sunday)
- Individual programs for each day of the week
- Same program for the whole week
Schedule of the second type example

First type schedule programming
Default program settings (1-3)
Within first type schedule mode there are 9 programs available. Programs 0 to
3 are factory-defined programs that cannot be changed. In this chapter you
will find detailed information on the built-in factory programs (1-3) in the
E901. These are pre-programmed time settings for the comfort and economy
temperature that can be assigned to a selected day. To set up the program, see
the steps below. The black squares on the timeline indicate the operating time
for the comfort temperature mode, while the absence of them – for the economy
temperature mode. Under the chart of each program, there is time (hour) when
each mode is active. By default, program 1 is set for each day of the
week.
PLEASE NOTE!
Programs should be set for all days of the week.
Choosing and programming user programs (4-9)
In order to program your own schedule its necessary to choose user program (4-9), because only user programs are editable. Then we must draw our own timeline using Sun/Moon buttons. Thermostat will be switching between two setpoint temperatures (Comfort and Economy) which are represented by Sun and Moon icons. Switching time is represented by timeline. See steps below how to programm your own schedule:
Example: below, program 4 will be defined for the MON – FR period with a
comfort temperature from 8:00 to 16:00 and economic from 0:00 to 8:00 and
16:00 to 0:00. Programming starts from 0:00.
Please note!
Programs 0, 1, 2, 3 are factory set and cannot be edited. Programs 4 to 9 are
user defined (editable). One program (e.g. program 4) can be assigned to
several days of the week. If this program is edited, the change affects all
days to which given program is assigned to.
Frost Protection program setting
Frost protection mode (program 0) protects heating system against freezing. It is recommended to set this program if you are planning a long winter trip or if you do not heat up for a long time. The thermostat will maintain a constant temperature of 7˚C, thus reducing energy consumption to a minimum.
PLEASE NOTE!
In the frost protection mode, the temperature setpoint can’t be changed and it is maintained constantly at 7°C.
Temporary override mode
When thermostat is running schedule (automatic mode) we can temporarily
override it by new setpoint temperature:
Second type schedule programming
There are three different configurations in a schedule type 1:
- Two different programs (timelines), separate program for working days (Monday to Friday) and separate program for weekends (Saturday to Sunday)
- Individual programs (timelines) for each day of the week
- Same program (timeline) for the whole week
Exemplary schedule setting for working days and
weekend:
Temporary override mode
When thermostat is running schedule mode we can temporarily override it by
setting new work mode or setpoint temperature:
Party mode
In the party mode, the user can override schedule with comfort setpoint
temperature by defined number of hours. To do this, follow the steps
below:
The maximum duration of party mode is 9 hours. The temperature setpoint does not change during this mode. When party mode is enabled, pressing SUN, MOON or AUTO button twice (or 3 times if backlight is OFF) will disable it and thermostat will go back to appropriate mode.
To cancel active party mode (example)
Holiday mode
Holiday mode is a special program temperature setpoint which thermostat will
maintain for specified days. During holiday mode thermostat is maintaining
frost protection setpoint temperature. To set holiday mode, follow the steps
below:
TO STOP HOLIDAY MODE
Key lock function
To UNLOCK the thermostat keys, follow these steps
The user has the option to set a PIN code, which he will have to enter each time he wants to unlock the buttons of the thermostat. To set a PIN code, go to parameter P12 (please refer to „Installer settings” section).
