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’t 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’t be used in condensation of water vapor conditions and be exposed to water action.
Wall mounting
Free-standing thermostat
With the bracket attached to the E901RF set, you can use the thermostat anywhere in the house and put it on a table, desk, etc. To use the bracket properly, see the steps below:
Receiver
The thermostat communicates wirelessly with the receiver. The receiver should be supplied with 230VAC, the maximum switching load of the receiver is 16A. Avoid installing the device in places directly exposed to water, moisture and air condensation. The receiver can operate in two different modes – AUTO (automatic) and MANUAL (manual). To select a specific mode, use the switches on the front of the receiver.
Receiver’s switch description
REMEMBER!: Thermostat (transmitter) will communicate with receiver only when both are paired together and receiver’s switches are set to ON and AUTO position.
Receiver LED indicators
The status of the receiver is indicated by two LEDs. These are LEDs with the following colors:
A detailed explanation of the meaning of the LEDs can be found in the table below:
| DESCRIPTION | |
|
The green LED lights up |
The receiver is connected to the 230V power supply. |
| The green LED flashes | The receiver is in the pairing mode (then you must activate the “SYNC” parameter in the thermostat). |
| The green LED is off | The receiver is disconnected from the 230V power supply or the left switch is in the OFF position. |
| The orange LED lights up | In automatic mode, the receiver received a heating / cooling signal from the thermostat.
The receiver was started in manual mode (left switch is set to ON and right switch is set to MANUAL) |
| The orange LED flashes | The receiver was paired but lost communication with the thermostat due to out of range or low battery in the thermostat. The receiver starts flashing after 40 minutes of time when it does not receive a signal from the ther- mostat. |
| The orange LED is off | In automatic mode, the receiver didnt get a heating / cooling signal from the thermostat.
The receiver is OFF in manual mode (left switch is set to OFF and right switch is set to MANUAL). |
Connection description
Before you start (first power on)
The thermostat is powered by two 1.5V AA alkaline batteries. Insert the batteries into the compartment under the front housing, paying attention to their polarity. The thermostat will start up showing the current software version and then go to the main screen.

Button description
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
- Switching between schedules (AUTO Mode) type 1 and 2
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.
- 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 the 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
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 the „Installer settings” section).
Pairing with the E901RX receiver
PLEASE NOTE!The E901RF thermostat is already paired with the receiver!
In order to pair the devices correctly, you must first prepare the receiver for synchronization!
WARNING! If the green diode on the receiver has not stopped blinking after 10 minutes, repeat the pairing process taking into account the distance between devices, obstacles and interference.
Transmission test
It is important to place the receiver and transmitter in places where nothing is interfering with the radio signal. The range of communication between the transmitter and the receiver in an open area is up to 60m. Radio transmission is influenced by many factors that can shorten the working distance, such as thick walls, drywall covered with aluminum foil, metal objects such as cabinets, general radio interference, etc. However, the range is sufficient for most domestic applications. It is recommended that the radio transmission between devices has to be tested before mounting the thermostat to the wall. The test can be performed by changing the set temperature, i.e. by activating or deactivating the heating.
Please note: If the orange LED does not turn on / off as indicated by the transmitter flame icon, try moving the transmitter closer to the receiver and repeat all steps from the beginning.
If it still doesn’t work, try the pairing process again.
